How do composite and wood decking compare?
| Factor | Composite (capped) | Wood (treated pine / cedar) |
|---|---|---|
| Upfront material cost | Higher | Lower |
| Ongoing maintenance | Wash periodically | Clean and re-seal or stain on a schedule |
| Look and feel | Consistent color, wood-grain texture | Natural grain that varies board to board |
| Heat in full sun | Darker colors can get hot | Usually cooler underfoot |
| Rot and insects | Highly resistant | Treated/heartwood resistant; rots where water is trapped |
| Splinters | None | Possible as wood weathers |
| Repairs | Scratches hard to fix; replace boards | Can be sanded and refinished |
| Framing | Often needs closer joist spacing | Standard spacing |
Is composite decking worth the extra cost?
Often, if you'll stay in the home for years and don't want to refinish wood. Over time, the cost and effort of staining narrows — and can close — the upfront price gap.
If budget today is the priority, or you enjoy natural wood and don't mind upkeep, wood is the practical choice. Many homeowners also split the difference: composite for the walking surface and treated wood for the framing, which is standard either way.
Which is better in wet, snowy or hot climates?
- Wet and shaded decks: capped composite or PVC resists moisture and mildew better than unsealed wood.
- Snow and freeze-thaw: composite tolerates freeze-thaw well; use plastic shovels and approved ice-melt.
- Hot, sunny decks: lighter composite colors or wood are more comfortable barefoot.
Which composite brands are common?
Widely available composite and PVC decking manufacturers include Trex, TimberTech/AZEK, Fiberon and others, each with several product lines at different price points. Compare the cap coverage, color options, heat-related features, warranty terms and required joist spacing rather than choosing by brand alone.
How do you decide between composite and wood?
- 1How long will you own the home?
- 2How much time will you realistically spend on maintenance?
- 3How much afternoon sun does the deck get?
- 4Is the existing frame (if re-decking) spaced for composite?
- 5What look suits the house and neighborhood?
How does composite vs. wood decking differ across the states we serve?
Summer heat is the main factor that tips some homeowners toward wood or lighter composite. The figure varies most between Tennessee (54) and Washington (2).
| State | 90°F+ days / yr (median) | What it means |
|---|---|---|
| Georgia | 51 | Hot summers: color, shade and heat build-up shape composite vs. wood decking |
| Illinois | 17 | Some hot days: test colors and finishes for composite vs. wood decking in full sun |
| Kansas | 39 | Some hot days: test colors and finishes for composite vs. wood decking in full sun |
| Maryland | 25 | Some hot days: test colors and finishes for composite vs. wood decking in full sun |
| Massachusetts | 14 | Mild summers: heat is a minor factor for composite vs. wood decking |
| Minnesota | 8 | Mild summers: heat is a minor factor for composite vs. wood decking |
| North Carolina | 49 | Hot summers: color, shade and heat build-up shape composite vs. wood decking |
| Pennsylvania | 22 | Some hot days: test colors and finishes for composite vs. wood decking in full sun |
| Tennessee | 54 | Hot summers: color, shade and heat build-up shape composite vs. wood decking |
| Virginia | 30 | Some hot days: test colors and finishes for composite vs. wood decking in full sun |
| Washington | 2 | Mild summers: heat is a minor factor for composite vs. wood decking |
