Composite, Trex and PVC decks in Rhode Island
Most RI deck quotes come down to three decking choices. The frame underneath is usually pressure-treated lumber either way.
| Pressure-treated wood | Composite (e.g. Trex, TimberTech, Fiberon) | PVC / cellular | |
|---|---|---|---|
| Up-front cost | Lowest | Higher (about $5,200 more on the 2025 New England benchmark deck) | Usually highest |
| Maintenance | Clean and re-stain/seal every few years | Wash; no staining | Wash; no staining |
| Moisture and salt air | Can check, split and gray; fasteners matter | Capped boards resist moisture; follow the maker's fastener rules | No wood content, very moisture-resistant |
| Heat in sun | Stays cooler | Darker colors get hot | Can get hot; lighter colors help |
| Resale (2025 New England report) | 79.1% of cost recouped | 95.8% of cost recouped | Not reported separately |
Resale and cost figures: 2025 Cost vs. Value Report, New England. Material characteristics are general; always follow the manufacturer's installation and warranty instructions.
Is Trex the only composite option?
No. Trex is the best-known brand, but builders also install TimberTech/AZEK, Fiberon and others. Ask each builder which lines they install, which collection they're quoting, and what the warranty requires.
Good fits in RI
- Seasonal and coastal homes: lower upkeep is the main reason people choose composite or PVC.
- Budget-first projects: pressure-treated wood is still the value choice, especially for low decks.
- Resurfacing: composite boards on an existing frame only make sense if the frame is sound and spaced correctly for the new boards.
