How Much Does Deck Replacement Cost?
August 18, 2026
The average cost for deck replacement can vary widely, with the final price depending on your deck size, features, material, and location.
Wood decks are prone to rotting, fading, and splintering after years of sun and weather exposure. They need annual maintenance and a new deck surface every 10 to 15 years to maintain their structure and appearance. If you own or are considering a wood deck, it's important to understand the deck replacement cost you will face in a decade or so.
Replacing your deck can be costly, but homeowners often enjoy a return on the investment. It's also a great opportunity to invest in a low-maintenance decking option like TimberTech. Our decking reduces your maintenance costs, features an authentic real wood look, and won't need replacing for several decades or more. Explore the costs of replacing your deck — as well as great decking alternatives for improved looks and performance.
Average cost to replace or repair a deck
Replacing your deck surface can range greatly in cost depending on the type of material you resurface with. Pressure-treated lumber ranges from $0.85-3.50 per linear foot, while an exotic hardwood like ipe ranges from $5.50-$15.00 per linear foot. Composite boards average $1.75-$8.00 per linear foot. But material cost is only part of the picture. Labor costs, if you choose to hire a professional, often accounts for a significant percentage of an entire deck project budget — and any add-ons like railing and lighting also play a role in total deck cost.
Working with a professional can help ensure your deck replacement goes smoothly. After inspecting any wood aspects of your deck for mold, rot, and splintering, a contractor can also help identify other necessary repairs like rotting joists or insufficient railing. If your deck requires a little more work than a fresh surface — like a substructure replacement due to rotting joists or some other failure — factor these expenses into your building budget.
Cost and quality vary among deck materials. Pressure-treated lumber is typically the most affordable decking board available; but it isn't as durable as hardwoods like ipe, so the long-term maintenance costs add up. Engineered decking materials, including composite and PVC, also offer several product ranges that vary in cost and features. However, you can save thousands in maintenance expenses over the long lifetime of your deck.
These price ranges can help you understand the cost differences between board materials:
- Pressure-treated lumber: $0.85-3.50 per linear foot
- Composite: $1.75-$8.00 per linear foot
- PVC: $4.25-$7.50 per linear foot
- Ipe: $5.50-$15.00 per linear foot
Common deck repairs
Common deck repairs include fixing substructure damage, treating mold, and replacing damaged boards and fasteners. A wood deck naturally decomposes, so you will likely need to replace it every 10 to 15 years and refinish it annually. Some specific problems are easier to repair than a brand-new deck surface if you spot them quickly enough. Other damage is more significant and requires a specialist. Here's an overview of common deck repairs to watch for.
- Substructure damage
- Pest damage
- Mold and mildew
- Refinishing
- Damaged fasteners
- Stair or step repair
Additional cost factors for your deck replacement or repair
Beyond material selection and labor, there are multiple factors that can influence the cost of your deck replacement, including deck size, shape, design, and geographic location. Simpler designs are more affordable upfront, while complex elevations increase the final price.
No matter how simple your deck design is, it's a unique structure. This means your deck replacement may cost more or less than the estimated average. Consider how these factors play a role in your repair budget. Keeping the design factors below simple can often help keep costs down.
- Deck size
- Deck shape
- Deck design (elevated, wraparound)
- Permits
- Site maintenance
- Geographic location (city, state)
- Property location (attached to house, on a slope)
- Disposal
Simpler designs like rectangles made of pressure-treated lumber are the most affordable upfront. However, higher quality manufactured deck boards and railing will reduce maintenance and repair costs long-term. More complicated engineering, like elevated decks on stilts or large multi-level structures with stairs, will also increase the price of your deck replacement. If you know your deck is an advanced build, factor that into your cost estimate. You can consult a professional contractor for an accurate quote before committing to a project.
