Composite vs Wood Decking in the Texas Sun
You are standing at the lumber yard holding a cedar board in one hand and a composite sample in the other. The composite costs more, and you want to know what the extra money buys in a Texas summer.
Wood costs less up front and stays cooler under bare feet, but it needs stain or sealer every couple of years. Composite costs more, skips the staining and will not splinter, but it can get hotter in full sun and needs tighter joist spacing.
- Pressure treated pine is the lowest cost and the most upkeep.
- Cedar looks warm and resists rot, but still needs sealer.
- Composite needs washing, not staining.
- Dark boards in full sun get hot, so color and shade matter.
Upkeep Over Ten Summers
Austin sun breaks down wood fast. Pine and cedar both turn gray and check without a stain or sealer, usually every two or three years on a sunny deck. Composite does not need stain. A wash with soap and a soft brush a couple of times a year keeps it clean.
Heat Under Bare Feet
Any deck board gets hot in direct July sun. Composite, and dark composite most of all, tends to feel hotter than wood. Picking a lighter color and putting shade over part of the deck, like a pergola, makes a bigger difference than the board brand.
| Treated pine | Cedar | Composite | |
|---|---|---|---|
| Up front cost | Lowest | Middle | Highest |
| Stain or sealer | Every 2 to 3 years | Every 2 to 3 years | None |
| Splinters | Can splinter | Can splinter | No |
| Feel in full sun | Warm | Warm | Hotter, darker is worse |
Splinters, Fading and Movement
Wood can splinter and cup as it dries. Composite will not splinter, but it expands and contracts with heat, so the gaps at the ends of boards have to follow the maker's spacing. Most composite colors fade a little in the first months of sun and then settle.
What Goes Under the Boards
The frame under a composite deck is still wood, so the footings and joists matter just as much. Many composite boards call for joists closer together than wood boards do, so the framing plan has to match the board you pick.
The Gaps
Brand brochures show composite in mild weather. They rarely talk about a dark board in direct afternoon sun, which is the first thing an Austin family notices in July.
