Decking

What is TimberTech Advanced PVC Decking and what is it made of?

PVC decking is a type of synthetic decking material made from polyvinyl chloride. It is known for its durability, low maintenance, and resistance to rotting, mold, and insect damage. PVC decking is a popular choice for outdoor spaces due to its long-lasting nature and ability to withstand harsh weather conditions. You can see the difference between PVC decking and composite decking here.

Fasteners

Are special tools required to install CONCEALoc® Hidden Fasteners?

No, special tools are not required for a standard installation of our CONCEALoc® Hidden Fasteners, making it simple to achieve a clean, fastener-free deck surface.

For grooved boards: You only need a standard drill/driver. We include the correct #1 square-drive bit with the CONCEALoc® clips and screws.

For solid boards: You will need a router fitted with our CONCEALoc® router bit to create the necessary groove at each joist.

Pneumatic option: For contractors looking for maximum efficiency, a pneumatic installation tool is also available through FastenMaster. You can find details on how to install CONCEALoc® in grooved and solid planks in this TimberTech CONCEALoc® installation video.

Decking

What are the benefits of TimberTech Advanced PVC decking compared to composite and wood?

PVC decking offers a real wood look with less maintenance than natural wood. Unlike composite materials, our Advanced PVC is completely synthetic, making it resistant to issues like mold, mildew, and rot. It’s lightweight yet durable, so it’s easy to install without compromising on strength. Plus, PVC decking resists fading and stains better than traditional wood or composite, giving you a beautiful, long-lasting outdoor space.

Decking

Does TimberTech Advanced PVC Decking get hot?

While all decking materials can warm under direct sunlight, TimberTech Advanced PVC Decking is designed to reduce heat retention and stays up to 30 degrees cooler than competitive composites. Its advanced materials help keep your deck cooler compared to other options, especially the lighter colors. For maximum comfort, consider installing lighter or reflective colors if your deck gets constant sun exposure.

Although TimberTech PVC Decking is cooler to the touch than many other deck board products, all decking products will get hot in the sun. Additionally, the darker the decking color, the hotter it will feel. For hotter climates, consider choosing a lighter color. See Cool Touch details here.

Decking

Does TimberTech Advanced PVC Decking perform well near water?

Yes, TimberTech Advanced PVC Decking is an excellent choice for areas near water, like pools, docks, and lakeside decks. Thanks to its 100% synthetic composition, PVC is moisture resistant and won’t warp, swell, or deteriorate from water exposure. It also has up to 40% better traction than competitive products, making it better for slip resistance in both wet and dry conditions. TimberTech Advanced PVC MAX boards are made specifically for dock applications.

Decking

How long can TimberTech Advanced PVC decking last?

TimberTech Advanced PVC Decking has a Lifetime Limited Product Warranty. Its strong, weather-resistant construction is engineered to endure sun, rain, and snow without fading, cracking, or rotting. With minimal upkeep required, Advanced PVC decking provides lasting beauty and performance, making it a smart long-term investment.

Decking

Is PVC decking good for the environment?

TimberTech Advanced PVC decking is designed with sustainability in mind. It’s made from up to 65% recycled materials and manufactured with processes that minimize waste. Additionally, its long lifespan and reduced need for chemical treatments make it a more eco-friendly choice than traditional wood decking. Choosing Advanced PVC means you’re investing in a product that helps reduce deforestation, and is better for both your home and the environment.

Decking

What is composite decking and what is it made of?

Composite decking is a type of alternative decking material made from a combination of wood fibers and recycled plastic. It is designed to mimic the look and feel of real wood while offering enhanced durability and lower maintenance requirements. See the benefits of composite decking here.

Decking

What are the different types of composite decking?

There are several types of composite decking, primarily differing in the level of protection they offer. The key difference lies in whether the board has a protective cap.

Capped composite decking: This is the modern standard for high-performance composite decking. A protective cap, or shell, is bonded to the composite core. This cap provides superior resistance to fading, staining, and moisture.

Advanced TimberTech Capping: Most TimberTech Composite decking features a four-sided cap that wraps around the entire board, including the grooves. This offers complete moisture protection, preventing issues that can arise with boards that are only capped on three sides.

Decking

How does composite decking compare to traditional wood decking?

Composite decking has several advantages over traditional wood decking. It is resistant to rot, decay, and insect damage, making it a longer-lasting option. Composite decking also requires less maintenance, as it does not need to be stained, sealed, or painted regularly like wood decking. You can learn more about TimberTech Vs Wood here.

Decking

Can I install composite decking myself, or do I need to hire a professional?

Yes, if you’re planning to build yourself, visit our deck building resource center for installation guides, helpful articles and more. While it is possible to install composite decking yourself, it may be best to hire a professional if you are not experienced in deck building. Professionals have the tools and knowledge necessary to ensure a proper and secure installation that will last for years to come. We can help match you to a  TimberTech contractor.

Decking

Is composite decking more expensive than traditional wood decking?

Initially, composite decking may have a higher upfront cost compared to traditional wood decking. However, over time, the lower maintenance requirements and longer lifespan of composite decking often make it a more cost-effective option in the long run. See the cost breakdown here.

Decking

Does TimberTech Composite Decking get hot?

Like most decking materials, TimberTech Composite Decking may get hot under direct sunlight, especially on very hot days. However, TimberTech offers options with lighter color choices that help minimize heat retention. Plus, TimberTech Advanced PVC Decking is designed to reduce heat retention and stays up to 30 degrees cooler than competitive composites. To keep your deck as comfortable as possible, consider selecting lighter tones or integrating shaded areas into your design.

Decking

Is composite decking good for the environment?

Yes, TimberTech Composite Decking is an environmentally-friendly, sustainable option. It’s made using up to 85% recycled materials, such as reclaimed wood fibers and plastics, reducing the need for virgin resources. Additionally, TimberTech’s manufacturing processes are designed to minimize waste and emissions. By choosing composite decking, you’re supporting sustainable practices and helping reduce deforestation while enjoying a durable, low-maintenance product.

Maintenance

What is the best way to clean composite decking?

The preferred way to keep your TimberTech deck clean is to use TimberTech DeckCleaner™ – a formulated, field-tested, and approved product for cleaning TimberTech Composite decking, and TimberTech Composite Rail. You can also use soap and water or an all-purpose cleaner such as Chomp® gutter cleaner, Zep 505®, Simple Green®, or Krud Kutter®. Check out our  Care & Cleaning Guide  for more instructions on how to clean TimberTech decks.

Decking

Can I install my porch pillars or hot tub on top of my TimberTech deck?

Yes. Please remember the underlying joist system, not the TimberTech boards, should be the primary structural supporting mechanism. TimberTech is not to be used as a primary structural load-bearing member.

Decking

I have a wood deck and want to replace some boards. Can I replace them with TimberTech boards?

Yes, you can replace old wood deck boards with our high-performance composite boards, but there are a few important things to consider first. You will need to confirm your deck's substructure is code-compliant and can support the weight of the new TimberTech boards. It is also important to match the thickness of the new boards to the old ones to ensure a smooth, even surface.

While replacing a few boards is possible, it can create a patched look. For a seamless, beautiful deck that offers superior longevity and low maintenance, we recommend a full replacement if your substructure allows it.

Decking

Does TimberTech decking require pre-drilling to install?

TimberTech Advanced PVC products do not require pre-drilling. TimberTech Composite products generally do not need pre-drilling, however there are a few specific situations where we do recommend pre-drilling to ensure the best results and prevent any damage:

• When installing in temperatures below 45°F (7°C)

• When using composite screws for specific applications

• When fastening within 1.5 inches of the end or edge of a board

Pre-drilling in these instances helps ensure a clean installation and protects the integrity of the board.

Decking

Can I use a router to create a groove in square shoulder TimberTech deck boards?

You should only rout a groove in a square-shoulder board when transitioning to grooved boards as part of a hidden fastener installation.

In this case, a 2-inch groove should be routed above each joist to accommodate the hidden fasteners. For detailed instructions, please consult the TimberTech Installation Guide.

Decking

Can I use glue or caulk with TimberTech decking?

No, you should not use glue or caulk to fasten TimberTech deck boards or to seal the gaps between them. Applying caulk or adhesives between the boards can restrict the natural expansion and contraction, which may lead to performance issues. Additionally, sealing the gaps can block proper water drainage from the deck surface.

Decking

Can I install TimberTech decking near saltwater?

Yes. TimberTech decking collections provide varying levels of moisture resistance and, unlike wood, are engineered to resist the corrosive effects of salt air and water. Our Advanced PVC, in particular, is an excellent choice for saltwater environments. Saltwater can accelerate the deterioration of wood fibers, but TimberTech Advanced PVC is made with no wood or organic fillers that can be compromised by saltwater. We highly recommend using 316 stainless steel fasteners.

Decking

Can TimberTech Decking be used as joists or structural supports?

No, TimberTech Decking cannot be used for structural purposes or for use as primary load-bearing components like columns, support posts, beams, or joist stringers. For a safe and long-lasting deck, your TimberTech boards must be installed on a code-compliant substructure that provides the necessary support, such as TimberTech Aluminum Framing. Always refer to our official Installation Guide for complete details.

Decking

Can I build my TimberTech deck directly over an existing deck?

No, you should not install new TimberTech decking directly over old or existing deck boards. For proper safety, long-term performance, and warranty coverage, you must remove the old decking before installing your new TimberTech boards.

Decking

Can TimberTech decking be installed in cold weather?

Yes, you can install TimberTech decking in cold weather. However, it requires special attention to gapping. When installing in colder temperatures, you must ensure the gaps between the boards are set correctly according to our Installation Guides. This allows the boards to expand without issue when the weather warms up.

Decking

What is the maximum joist spacing for TimberTech decking?

Maximum joist spacing on a deck's surface for standard TimberTech deck boards is 16" on center for residential applications. TimberTech Advanced PVC MAX boards can span 24" on center. For stairs, landings, angled installation of deck boards, and commercial applications, please refer to our decking installation guides for the joist spacing required. You should always follow local building codes.

Decking

Can I install TimberTech products myself or do I need to hire a contractor?

Yes, you absolutely can install TimberTech products yourself. Many of our decking, railing, and lighting systems are designed with the skilled DIYer in mind. We provide extensive resources, including detailed installation guides and videos, to help you complete your project successfully.

Decking

What is the minimum height from the ground that TimberTech Decking must be installed?

The minimum required ground clearance is 1.5 inches. This gap allows for necessary airflow, which helps to prevent moisture buildup and keep your deck substructure dry.

Decking

What is the recommended spacing for TimberTech stair stringers?

We recommend specific spacing based on the type of TimberTech decking you are using for your stair treads.

For TimberTech Advanced PVC Decking, the maximum spacing for stair stringers is 12 inches on center.

For TimberTech Composite Decking, the maximum spacing is 9 inches on center.

Warranty

How do I transfer my TimberTech warranty if I sell my house?

To ensure a smooth transfer, you will need to provide the new owner with specific documentation from the original installation.

Key Steps for Warranty Transfer:

Gather documents — collect the original purchase invoices for the TimberTech products and a copy of the dated installation contract.

Provide to new owner — pass these documents to the new homeowner at the time of the property sale.

Proof of transfer — the new owner should keep these documents along with their own proof of property transfer (e.g., closing documents).

In the event of a future claim, the new owner will need to provide this complete set of documentation. This validates that the ownership transfer occurred within the transferable period defined by your specific product warranty. This process ensures the next owner can enjoy the same lasting protection and peace of mind.

Warranty

What information do I need to file a TimberTech warranty claim?

Here is what you will need to file a TimberTech claim:

Proof of purchase — this can be the original invoice, a receipt, or a bank/credit card statement showing the purchase.

Photos of the issue — clear pictures of the affected decking or railing area help us understand the specific concern. Please also include a photo showing the end of a board where the product information is printed.

Property owner information — the name and address of the current property owner where the TimberTech product is installed.

Product details — information about the specific product, such as the color, dimensions, and the date of installation.

Our team is here to guide you through the warranty process. Having this information ready helps us provide a quick and accurate resolution.

Warranty

What is required within the requested photos for a warranty claim?

To ensure we have all the information we need, please include the following photos with your claim:

Overall view — a few pictures of the entire deck or railing project from different angles. This gives us context for where the issue is occurring.

Close-up of the issue — clear, detailed photos of the specific area of concern. Please show the problem from multiple perspectives if possible.

Product identification photo — a picture of the end of an affected board showing the printed product information. This detail is essential for us to identify the exact product and manufacturing date. For concerns regarding structural movement or warping, place a straight edge on the deck surface to provide a reference point to better illustrate the area of concern. (Common straight edges are a builder’s level, board, broom handle, etc.) Photos specific to areas with aesthetic concerns do not require a straight edge reference point. Clarity of photos will expedite the review process. Each image file is limited to 5 MB.

Other documents that may work include:

Bank or credit card statements showing the transaction
A copy of your contract with the builder
Other records from your contractor

Claims submitted without an original sales invoice to define material type, lengths, quantities, and retail point of purchase will result in delays. Additional details may be requested dependent upon the nature of the product claim.

Maintenance

Can I use rock salt or ice melt on a TimberTech deck?

Like any walking surface, your deck can become slippery, so it's wise to take precautions. While you should avoid using rock salt or other abrasive ice melt products, you can use certain ice melt products on your TimberTech deck to improve safety during winter weather.

We recommend products containing calcium chloride, as they are effective and will not damage the deck surface — though they may leave a white residue that can be easily cleaned off later. For a pet-friendly option, most products containing magnesium chloride are also safe for your deck. Use a plastic shovel without a metal edge to clear snow. A metal blade can damage the deck's surface.

Maintenance

How do I clean TimberTech Rail?

TimberTech Composite, PVC, Premium Vinyl, and Aluminum Railing can be cleaned using a soft white cloth with TimberTech Deck Cleaner, followed by a thorough rinse. DO NOT USE Solvent-based cleaners such as Goof Off, Graffiti Remover, Nail Polish Remover, or similar products on TimberTech Rail. Fulton Rail™ can be cleaned by using mild soap and water.

Maintenance

Can I powerwash my TimberTech deck?

While powerwashing a TimberTech deck is not the preferred way to clean, yes, you can powerwash TimberTech decking. It’s important to follow these specific guidelines to protect your deck’s surface and warranty: • Use a pressure washer with a maximum rating of 1,500 PSI • Always use a fan tip nozzle. Never use a pinpoint or needle-tip nozzle, as this can damage the deck surface.

• Keep the spray nozzle at a safe distance from the decking surface.

• Spray in the direction of the grain to avoid leaving marks.

Refer to the TimberTech Care and Cleaning Guide for more information.

DrySpace

Can I paint TimberTech DrySpace?

No, we do not recommend painting the TimberTech DrySpace underdeck drainage system. Applying paint or other finishes can interfere with the material's performance and will void the product warranty. We offer this product in two colors; Bone and White

DrySpace

Can I splice TimberTech DrySpace panels together to save material?

No, we do not recommend splicing or joining TimberTech DrySpace panels. Creating a joint between panels or joist covers compromises the system's integrity and cannot be sealed effectively to prevent leaks. DrySpace is available in 12' and 16' lengths.

DrySpace

Can I install the TimberTech DrySpace system myself?

Yes. Complete, easy-to-follow instructions come with your DrySpace purchase or you can refer to our Installation Help Guide. Installation is easiest with two people. The everyday tools and materials you will need are readily available, and easy to find at your local hardware store.

DrySpace

What happens to the dirt and debris that falls through the gaps between the deck boards with TimberTech DrySpace installed?

TimberTech DrySpace® is a deck drainage system that collects water and debris that falls between the gaps in the planks and channels it away. When a deck is installed using the proper gapping requirements between planks and DrySpace is installed with the proper pitch, dirt and debris are able to fall through and be channeled out of the DrySpace panels and through the optional gutter, which helps keep your space below clean and dry. Check out our DrySpace installation video and Installation Guide for more detailed information.

DrySpace

Will melting and refreezing snow cause TimberTech DrySpace to fail?

No. Properly installed, our TimberTech DrySpace system will not fail due to melting and refreezing snow. If the TimberTech DrySpace has been installed with the proper pitch as defined within the Installation and Maintenance Guide, the majority of the melt-off would channel out of the panel rather than freeze.

DrySpace

Will the DrySpace Combo Bracket cause my deck substructure to rot?

No, when properly installed with the specified pitch, the DrySpace Combo Bracket is specifically designed to prevent moisture buildup and will not cause your deck's substructure to rot.

DrySpace

Can I run DrySpace V-panels over the top of a beam?

No. To ensure proper water drainage, the panels must stop 3 inches away from the beam. The Combo Brackets should stop 1 inch from the beam. For a successful installation, it is crucial that the low point of the panel does not interfere with the beam, which could cause water to dam on the panel.

DrySpace

Could I install TimberTech DrySpace by using F-Brackets only and not the Combo Bracket?

No, the Combo Bracket is a required component for a proper TimberTech DrySpace installation. The Combo Bracket must be used to collect any water that drains through or around the joist.

DrySpace

Can I install a more decorative ceiling under the TimberTech DrySpace system?

No, we do not recommend attaching a decorative ceiling directly to the DrySpace underdeck drainage system. This would puncture the combo brackets with nails or screws, therefore compromising the integrity of the DrySpace system.

DrySpace

Will deck cleaners damage DrySpace?

TimberTech DeckCleaner™ will not damage the DrySpace system, and it can actually be used to clean the surface of DrySpace. Any other cleaners should be verified to be vinyl-safe before using.

General

What sizes are available in TimberTech gate kits?

General

Can TimberTech deck boards be used as cladding in commercial applications?

TimberTech Advanced PVC decking has been approved for use in the following uses: As an exterior wall cladding on buildings of Type V-B construction (IBC, FBC) and all construction types permitted under the IRC and FBC-Residential; as an exterior wall cladding on buildings of Types I-IV construction (IBC 1405.1.1, FBC 1406.2.1), and as an exterior wall cladding on fire-resistance rated walls (IBC and FBC 703.2).

Fasteners

Does TimberTech offer hidden fasteners for installing TimberTech Advanced PVC decking as cladding?

Yes, TimberTech recommends our Cortex® hidden fastener system, which conceals the screws with plugs made from our decking. Our Cortex® fasteners are offered with a 2½” screw, and we also offer a version of Cortex® with a 2” screw designed specifically for cladding applications over block construction. Other hidden fasteners, like TimberTech’s CONCEALoc® fasteners or any competitive hidden fasteners are not recommended for the cladding application.

General

What do you recommend for a weather-resistant barrier or waterproofing?

Each application is entirely different. The substructure must be built to be weatherproof. Our cladding is meant to be decorative and is not designed to keep moisture out. It is up to the architect, engineer, installer, and local code official to ensure the structure is weather-tight and meets code.

General

Maintenance

Will TimberTech Decking get mold on it?

We manufacture all products to be highly resistant to mold and other damage from moisture. In rare cases and depending on environmental conditions (temperature, moisture in the air, etc.), mold and mildew could appear on any outdoor surface. If mold occurs on the surface of TimberTech decking, it does not penetrate through the deck board. Surface mold and mildew on TimberTech decking can be removed using TimberTech DeckCleaner or a 1-to-4 mixture of bleach and water.

General

Can I cantilever TimberTech boards on my deck?

Yes, TimberTech decking can be cantilevered. TimberTech Advanced PVC decking can be cantilevered a maximum of 1/2″. TimberTech Composite full profile deck boards can be cantilevered a maximum of 1″. TimberTech Composite scalloped profile deck boards (Terrain, Prime and Prime+ collections) can only be cantilevered on the ends of the board a maximum of 1″.

Maintenance

Can TimberTech decking be painted or stained?

We do not recommend painting or staining TimberTech Decking. TimberTech cannot guarantee the results of third-party products applied to our decking, and any resulting issues would not be covered under our warranty.

Decking

Is TimberTech Decking code compliant?

Yes, all TimberTech decking products are thoroughly tested to meet and often exceed building code requirements. You can find detailed code compliance research reports (CCRR) for all our decking and railing products on our Technical Resources page.

General

Does TimberTech decking really resist fading?

Yes, while any exterior products will fade over time to some degree, all of our lines of decking are engineered to be fade and stain-resistant. TimberTech Advanced PVC decking and porch products are backed by our 50-Year Fade & Stain Warranty. TimberTech Composite decking products are backed by our 30-Year or 25-Year Fade & Stain Warranties; depending on the collection.

General

Can TimberTech Decking be used for a wheelchair or walker ramp?

Yes, TimberTech Decking is an excellent material for constructing durable, slip-resistant wheelchair and walker ramps. For detailed building requirements, always consult the ADA standards and local building codes.

General

Do I need to place something on furniture legs to protect my TimberTech decking from scratches?

While TimberTech decking is engineered for exceptional scratch resistance, we recommend using protective plastic, felt, or rubber pads on the legs of your outdoor furniture. This simple step helps preserve the beautiful, real-wood look of your deck surface.

General

Does TimberTech have a bench and/or planter system?

While we do not offer pre-fabricated bench or planter kits, TimberTech decking is the perfect material for creating your own custom, built-in features. We recommend working with your local contractor to help design and build your benches and planters.

Porch

Can TimberTech Advanced PVC Porch boards be used near water?

Absolutely, yes. TimberTech Advanced PVC Porch boards have the same level of moisture resistance as our Advanced PVC Deck boards. That makes them an excellent choice for applications near water — such as around pools, hot tubs, and on docks. Consider checking our TimberTech MAX boards made specifically for docks.

Porch

What is the difference between TimberTech Advanced PVC Deck and TimberTech Advanced PVC Porch boards?

TimberTech Advanced PVC Deck and TimberTech Advanced PVC Porch are made of the same high-performance material, but the difference comes in their application and installation. TimberTech Advanced PVC Decking is designed for standard deck construction. They are installed with slight gaps between the boards to allow for drainage, making them ideal for uncovered, open-air spaces. TimberTech Advanced PVC Decking is available with square edges or grooved edges and are available in 12', 16', and 20' lengths.

TimberTech Advanced PVC Porch features a tongue-and-groove system that allows them to fit tightly together. This creates a solid, gap-free surface that is perfect for covered, semi-enclosed spaces like porches or three-season rooms, protecting the area below from water. These are available in 10′, 12′, and 16′ lengths.

Railing

What size TimberTech Secure Mount Post do I need?

The Secure Mount Post is adjustable and accommodates 36" and 42" railings. We also offer a 6" Secure Mount Post Adaptor to make the Secure Mount Post compatible with our 6" Post Sleeve.

Railing

Can I use an aluminum baluster with TimberTech Rail?

Yes, you can pair most TimberTech railing collections with our aluminum balusters to create a custom look. We offer both round and square aluminum balusters, which can be installed with a Custom Rail Pack for a perfect fit.

For those who prefer a complete metal railing system, we also offer our Impression Rail Express®, which is made from aluminum, and Fulton Rail, which is made from steel.

Railing

Are there glass panel options for TimberTech railing?

Yes, we offer a specialized Glass Channel Kit designed for a seamless and secure railing installation.

Our Glass Channel Kits allow you to install glass infill with popular railing lines, including: Classic Composite Series and Impression Rail Express.

The kits are available in 6-foot lengths. Classic Composite is availble in Black and White. Impression Rail Express is available in Black, White and Dark Bronze. Please note that the glass panels are sourced and sold separately.

Railing

How do you install TimberTech railings on concrete?

While steps for installing TimberTech Railing vary by railing collection, the general process involves using our specially designed hardware for concrete surface applications. This typically includes a TimberTech Secure Mount Post system and appropriate concrete anchors. The Secure Mount Post is adjustable to accommodate both 36" and 42" high rail installations. The Secure Mount Post can be installed directly on composite decks or concrete surfaces, and no treated 4x4 post is needed. Mounting hardware for deck installation is sold separately. Mounting hardware for concrete applications can be sourced locally.

We recommend reviewing the specific installation guide for your chosen railing style before you begin.

Railing

What is the benefit of using the rail bracket?

Our TimberTech Rail brackets are engineered to provide a stronger, more secure connection between your railing and posts. This ensures long-term safety and stability for your entire railing system.

Railing

What is included in a TimberTech Glass Channel kit?

Inside each Glass Channel Kit, you will find:

• Top and bottom channels for one railing section

• All necessary gaskets

• Mounting hardware and fasteners

Please note that the glass panels themselves are not sold by TimberTech and The TimberTech Glass Channel kits do not contain the glass panels. Please consult your contractor.

Railing

Can TimberTech railing and decking products be curved or bent?

Yes, TimberTech Railing and Decking can be curved or bent using heat and force to create custom shapes. Because curving/bending is performed by customers on their own or by third-party fabricators, TimberTech cannot guarantee the integrity or performance of such applications, including the potential effect to the products’ structural rigidity, aesthetics, or other product attributes. Any problems to the decking or railing products resulting from curving/bending are expressly excluded under the TimberTech Limited Warranty. We recommend that all designs be reviewed by a licensed architect, engineer, or local building official before installation.

Railing

Can you paint TimberTech Rail?

While it is possible to paint TimberTech railing, the protective capstock on the railing is designed to resist any foreign material from sticking to it. Therefore, most paints will typically not adhere well to the railing components and TimberTech cannot guarantee the performance of paint, stain, or other materials applied to the product.

Railing

What are the differences among TimberTech railing collections?

TimberTech offers 8 railing collections across 5 material types: PVC, Composite, Aluminum, Steel, and Premium Vinyl. Beyond the material type, the primary differences between collections include top rail styles, available colors, infill options, and warranty coverage.

Railing

What comes in the TimberTech Rail Pack?

Classic Composite Series offers a Universal Rail Pack that contains 1 Universal Rail, 2 Support Rails, Hardware, and Footblocks (top rails sold separately). RadianceRail Express Packs contain the Top & Bottom Rail, Hardware, Gaskets, and Footblocks. Reserve Rail Packs contain Bottom Rail, 2 Support Rails, Hardware, and Footblocks (top rails sold separately). Infill options are sold separately to allow for more custom styling. Impression Rail and Impression Rail Express are only sold in Rail Kits, which include balusters.

Railing

What comes in the TimberTech Rail kit?

A TimberTech Rail kit contains the top rail, bottom rail, two support rails, balusters, and hardware to attach the railing section to the posts. Rail kits do not include posts, just the railing parts between the posts. TimberTech Rail kits are only available in white for the Classic Composite Series and are available in 6’ and 8’ sections.

Railing

What comes in the TimberTech Baluster pack?

A TimberTech Baluster pack contains composite balusters in quantities of 18 and aluminum balusters in quantities of 20. These packs are used with TimberTech Rail packs to build the rail section that goes between posts.

Lighting

Where do I put TimberTech deck lights on the stairs? How many should I install?

TimberTech Riser Lights are typically centered on the vertical surface of each step. We also offer Post Cap, Accent Lights, In-Deck lights, and Under-Rail lights for more illumination at the top and bottom of the stairs. Some municipalities have differing codes specific to stair lighting, so be sure to check your local code requirements before installation. The number of lights you install on your stairs is largely a personal preference — so have fun with it. For inspiration, check out TimberTech Lighting.

Lighting

What is the wattage on TimberTech LED deck lights?

The wattage of the TimberTech LEDs depends on the type of deck light you are using. Here is a quick breakdown of the wattage for each light style:

• Post Cap Light, In-Deck Light, and Riser Light — 2 watts

• Under-Rail Light — 4 watts

Lighting

Do you need to use a TimberTech Transformer with the LED Lighting product?

Yes, using a TimberTech Transformer is required to ensure the safety, performance, and warranty coverage of your new deck lighting system. Using a third-party transformer or power supply is not recommended, as it can lead to performance issues and will void the lighting warranty. The TimberTech Power Pack 150W delivers consistent performance with remote controlled dimming, and scheduled on/off options.

Fasteners

Can I use CONCEALoc® Hidden Fasteners for angled deck patterns?

Yes, our CONCEALoc® Hidden Fasteners are designed to work perfectly with angled decking installations, such as herringbone or diagonal patterns, up to 45 degrees. To ensure a secure installation when working with angles, simply offset the center of the fastener by ½ inch towards the long point of the joist.

Note: CONCEALoc is compatible with TimberTech grooved decking boards only.

Decking

Can TimberTech Decking be used for rooftop applications?

Yes, all TimberTech deck boards can be used for rooftop applications. Special considerations should be taken for rooftop applications. Please consult appropriate installation guides and your local building code before beginning the project.

Fasteners

Can TimberTech Cortex fasteners be used with all TimberTech decking?

The TimberTech Cortex® hidden fastening system is designed specifically for our square-shoulder deck boards. It is not compatible with our grooved-edge boards from the Terrain, Prime, and Prime+ collections. For our grooved-edge boards, we recommend using our CONCEALoc® hidden fasteners.

Fasteners

Do I need to gap my deck boards when using CONCEALoc® Hidden Fasteners?

Yes, proper gapping is essential, and our CONCEALoc® Hidden Fasteners make it simple. The fasteners are designed to automatically create the correct side-to-side spacing for your deck boards during installation. While the CONCEALoc® clips manage the side-to-side gap, you must also ensure you leave the appropriate end-to-end spacing where boards meet. Always refer to the TimberTech installation guide for specific gapping requirements for your chosen decking line.

Fasteners

Does CONCEALoc® match the decking colors?

No, our CONCEALoc® hidden fasteners are not designed to match the specific colors of our deck boards. Instead, CONCEALoc® (available in brown) is produced to blend naturally into the shadows between the boards.

Railing

How close to the rails can you safely have a barbecue grill without damaging TimberTech Railing?

To protect your investment and ensure safety, you must always follow the clearance requirements specified by your grill's manufacturer, as it can vary by type of grill and by size. Most grill manufacturers will have recommendations for placement in proximity to vinyl siding, and you can follow those same recommendations for TimberTech Railing. For further protection, a grill mat can be placed under the grill to avoid grease spills. You will want to make sure the grill mat is safe for composite decking.

Fasteners

What are the CONCEALoc Hidden Fasteners made of?

Our CONCEALoc Hidden Fasteners are made from Grade 304 stainless steel. This material is chosen for its exceptional durability and corrosion resistance, ensuring a secure, long-lasting installation for your deck. The hand-driven screws are stainless steel, while the pneumatically driven screws are coated carbon.

Fasteners

Can FUSIONLoc be used for TimberTech Decking?

TimberTech no longer produces FUSIONLoc Hidden Fasteners, but they are compatible with all of our grooved deck boards.
