Specialty Decking


Offering all of the benefits of composite decking at a price you can afford, the ReliaBoard helps make your deck dream — of friends, wine, and a picturesque sunset — a wonderful reality.

Texturized to create the appearance of wood with a surface grain pattern that will weather naturally to a consistent color.


Less Work, More Play

No annual sealing or staining required, giving you more free time simply relaxing on your deck.

Stands Up to the Weather

Built to resist mold, mildew, and moisture damage — whatever Mother Nature brings its way — and to last.


Lightweight and Strong 

A scalloped profile bottom reduces weight without sacrificing durability and strength.

The Best Warranty Coverage

TimberTech decking is engineered the right way, to last. Coverage includes the industry’s best 30-Year Limited Lifetime Warranty, fully transferable to another homeowner.  See full warranty details.

What kind of fastener should I use with TimberTech?

CONCEALoc is our most popular fastener for use with our grooved boards for a fastener-free finish. Cortex or TOPLoc are two other fastener options that can be used for just stairs and perimeters, or the entire deck. Cortex provides a discrete hidden-fastening solution, while TOPLoc provides an engineered, color-matched option. 

Please note that not all fasteners are compatible with all TimberTech decking boards, and using the incorrect fastening system will void your warranty. For example, CONCEALoc Hidden Fasteners or L-Brackets should not be used for stair installation. Always use the fasteners that are specifically recommended to work with your chosen TimberTech product. Refer to our Installation Guides for details.

Can TimberTech be painted or stained?

We do not recommend painting or staining TimberTech decking. While it is possible to paint our uncapped composite boards, TimberTech cannot guarantee the performance of paint, stain, or other materials, applied to the product. For further information on painting or staining your TimberTech decking, refer to our Care and Cleaning Recommendations.
