If you built a composite deck in Cary five to seven years ago thinking it would look new forever, you're not alone. The marketing around composite decking sells it as maintenance free and fade proof. The reality is more nuanced. While Composite Decks hold up better than wood against rot and splintering, they still show wear. Fading from UV exposure, surface scratching from furniture and pets, and a general dulling of color are common complaints among homeowners in McHenry County. The question isn't whether your deck will age. It's whether resurfacing it makes more sense than tearing it out and starting over. For many Cary homeowners in 2026, the answer is a clear yes.
When to Resurface vs. Replace Your Composite Deck
The decision to resurface or replace comes down to the condition of your substructure. Composite deck boards are the skin. The framing, joists, and ledger board underneath are the skeleton. If the skeleton is solid, resurfacing is almost always the smarter financial move. If the framing has rot, insect damage, or structural issues, you need a full replacement.
Resurfacing means removing the old composite boards and installing new ones on top of the existing frame. This is a good option when your deck is less than 15 years old, the framing passes a thorough inspection, and the only problems are cosmetic. Replacement means demolishing everything down to the footings and starting fresh. That costs roughly two to three times as much and takes longer.
A quick rule of thumb: if you can push a screwdriver into the bottom of a support post or joist more than a quarter inch, you're looking at replacement. If everything feels solid and dry, resurfacing is on the table. Burns Carpentry does a free structural assessment as part of every estimate, so you don't have to guess.
Composite Deck Resurfacing Cost Breakdown for Cary Homes
Pricing for composite deck resurfacing in the Cary area in 2026 typically runs between $25 and $45 per square foot. That range depends on three factors: the brand of composite you choose, the complexity of your deck's layout (multiple levels, angles, or built in features add cost), and whether you need any minor repairs to the substructure before the new boards go on.
For a standard 300 square foot deck, you're looking at roughly $7,500 to $13,500 for a full resurface. That includes removal of the old boards, inspection and minor repairs to the frame, installation of new composite decking, new fascia and trim, and cleanup. A full replacement of the same deck would run $18,000 to $30,000 depending on materials and design complexity. That's a significant difference.
Material choice matters: Entry level composites like Trex Select or MoistureShield run toward the lower end of that range. Premium lines like Trex Transcend or TimberTech AZEK cost more but offer better fade resistance and longer warranties. The labor cost stays fairly consistent regardless of material, so the biggest variable is what you put on top.
Step-by-Step: What Resurfacing Involves for Your Deck
A professional resurfacing project follows a predictable sequence. Understanding it helps you know what to expect and what questions to ask when getting quotes.
- Site preparation and protection: The crew moves furniture, grills, and planters. They lay down plywood or tarps to protect your lawn and landscaping. This usually takes half a day.
- Demolition of old deck boards: Every existing composite board gets removed. The crew works carefully to avoid damaging the underlying frame. Hidden fasteners come out. Surface screws get pulled. This is noisy and takes one to two days for an average deck.
- Structural inspection and repair: With the frame exposed, a carpenter checks every joist, beam, post, and connection. Any rotted or compromised lumber gets replaced. Loose hardware gets tightened. This step separates good contractors from great ones. A thorough inspection here prevents problems down the road.
- New composite decking installation: The new boards go down using hidden fasteners for a clean look. The crew follows the manufacturer's spacing and fastening specifications to the letter. This protects your warranty and ensures the boards have room to expand and contract through Illinois winters and summers.
- Trim, fascia, and finishing: New fascia boards cover the exposed edges. Stair treads and risers get resurfaced. Railings may need adjustment or replacement depending on their condition. The crew does a final cleanup and walks you through the finished deck.
The whole process typically takes one to two weeks for a standard residential deck. Burns Carpentry manages the entire timeline and keeps you updated on progress.
How Resurfacing Affects Your Deck's Warranty & Lifespan
One of the biggest advantages of resurfacing is that you get a fresh manufacturer warranty on the new deck boards. Most quality composites come with 25 to 50 year limited warranties against fading, staining, and structural defects. That warranty starts from the date of installation, not from your original deck build.
Your existing substructure doesn't get a new warranty, but it still has plenty of life left if it passed inspection. Pressure treated lumber properly installed and maintained lasts 20 to 30 years in northern Illinois. If your deck is 10 years old and the framing is solid, you're looking at another 10 to 20 years before the substructure becomes a concern.
Warranty gotcha to watch for: Some composite manufacturers require that only certified installers handle the resurfacing to keep the warranty valid. Always verify that your contractor is an authorized installer for the brand you choose. Burns Carpentry is certified for multiple composite lines and handles all warranty paperwork directly.
3 Signs Resurfacing Is the Right Call for Your Deck
Not every deck is a good candidate for resurfacing. Here are three signs that point to resurfacing being the smarter option.
1. Fading and discoloration without structural damage: If your composite boards have gone from a rich brown to a chalky gray but the surface is still solid and the frame is sound, resurfacing gives you a like new deck without the cost of replacement. UV exposure in Illinois can be harsh, especially on south and west facing decks. A fresh layer of premium composite with better UV stabilizers solves that problem for another 25 years.
2. Surface wear from high traffic areas: Composite decks in Cary that see heavy use near the door, around the grill, or along main walkways often show scratching and scuffing. These are cosmetic issues that don't affect structural integrity. Resurfacing replaces those worn boards with new material that can handle the traffic.
3. You want to upgrade the look or style: The composite colors and finishes available today are dramatically better than what was common even five years ago. If your deck was built with a basic brown or gray that no longer matches your taste, resurfacing lets you switch to a modern color like a cool gray, cedar tone, or tropical hardwood look. You can also change the board width or pattern without rebuilding the whole structure.
Frequently Asked Questions
How much does it cost to resurface a composite deck in Cary, Illinois?
Most homeowners in Cary pay between $25 and $45 per square foot for composite deck resurfacing in 2026. That includes removal of old boards, structural inspection, minor frame repairs, and installation of new composite decking. A 300 square foot deck typically runs $7,500 to $13,500.
Can you resurface a composite deck if the frame is still good?
Yes, that's the ideal scenario. If the substructure passes a thorough inspection with no rot, insect damage, or structural issues, you can absolutely resurface. The new boards go on top of the existing frame, giving you a brand new surface without the cost of foundation work.

Does resurfacing a composite deck void the original warranty?
No, but the original manufacturer warranty on the old boards is usually expired or minimal by the time you resurface. The new composite boards come with their own warranty, often 25 to 50 years, starting from the resurfacing date. Make sure your installer is certified for the brand to keep that warranty valid.
