If you've ever spent a Saturday in July scrubbing and sealing a wood deck, you already understand why composite is popular. You trade a higher price at the start for a lot less work every year after.
Composite deck installation in Kannapolis
Composite boards are made from a blend of wood fibers and plastic, usually with a tougher outer shell. Brands like Trex or TimberTech are common examples, and there are several others. Composite decking goes over a solid pressure-treated frame, which is how nearly all composite decks are built.
In Kannapolis, a few things make composite worth a hard look:
- Pine pollen. Every spring the deck turns yellow. Composite rinses off with a hose and a soft brush.
- Humidity and rain. Composite doesn't soak up water the way wood does, so it won't check, split or splinter.
- Kids and bare feet. No splinters is a real selling point for families.
The honest downsides
Composite is not perfect, and we'd rather you hear it from us now:
- It costs more. The same size deck in composite carries a noticeably higher upfront price than pressure-treated wood, mostly because the boards cost more.
- Dark colors get hot. Strong afternoon sun in Kannapolis can make dark boards uncomfortable for bare feet. Lighter colors and shade help a lot.
- It's not zero maintenance. It still needs washing a couple of times a year, and mildew can show up in shady, damp spots if it's ignored.
- The frame is still wood. The boards last a long time, so the framing underneath needs to be built and protected well enough to keep up.
How a composite deck should be built
Composite asks a bit more of the framing than wood does:
- Tighter joist spacing. Many composite boards need joists closer together than typical wood decking. A good installer follows the board maker's spacing.
- Joist tape. The crew covers the tops of joists so water doesn't sit in the screw holes and rot the frame early.
- Proper gapping. Composite expands and contracts with temperature. Boards are spaced for summer heat.
- Hidden or color-matched fasteners. Most homeowners want a clean surface with no visible screws.
- Ventilation. Low decks need airflow underneath, or moisture builds up in our humid summers.
Permits and inspections are usually required, and the contractor pulls them. NC811 is called before digging footings.
Picking a color with the sun in mind
Look at which direction your deck faces before picking a color. A shaded north or east deck can handle a darker board. A west-facing deck in full afternoon sun usually does better with a lighter gray or tan, or with a covered deck section for shade.
Ask the contractor to bring samples to the estimate. Set them in the sun for ten minutes and touch them. It's the easiest way to choose.
Texture matters too. Boards with a deeper grain pattern hide pollen, scuffs from patio chairs and dog claws better than smooth, solid-color boards. Mixed-tone boards also hide dirt between washings.
Signs composite is a good fit
- You plan to stay in the house for years.
- You don't want to stain or seal anything, ever.
- You have kids or pets on the deck barefoot.
- Your deck gets a lot of pollen, rain or shade-damp areas.
If you're more budget-focused, or might move in a few years, a well-built wood deck may make more sense. That's a fair choice, and a good builder can do either.
Replacing wood boards with composite
If your existing deck has solid framing, the wood boards can sometimes be swapped for composite. The builder should check joist spacing, joist condition and the ledger first. If the frame isn't up to it, you should hear that plainly, and it may be a deck replacement job instead.

Questions people ask
How long does a composite deck last?
Composite boards generally hold up much longer than a wood walking surface because they don't soak up water, check or split. The framing underneath is what usually decides a deck's lifespan, which is why joist protection, flashing and ventilation matter so much.
Does composite decking get hot in the summer?
It can, especially darker colors in direct afternoon sun. Lighter colors stay noticeably cooler. Shade from a roof, pergola or nearby trees also helps. Factor in your deck's direction when you pick a color.
Can composite go over my existing deck frame?
Sometimes. The joists need to be sound and spaced for the composite boards you choose. Many older wood decks have joists too far apart, which would need added framing. The contractor checks this at the free estimate.
How do I clean a composite deck?
Rinse it with a hose and use a soft brush with mild soap a couple of times a year, especially after pine pollen season. Avoid harsh pressure washing unless the board maker says it's allowed.
