Quick answer
Composite and PVC decking cost more up front but won’t rot, splinter or need yearly staining, which makes them the low-maintenance choice for shore homes. Pressure-treated wood costs less and performs well if you clean and seal it regularly. Near salt water, stainless or hot-dipped galvanized hardware is essential either way.
A deck is outdoor living space, and at the shore it takes a beating from UV, salt spray, sand and winter freeze-thaw. Here’s how the main options compare.
Pressure-treated wood
Pressure-treated lumber is the budget-friendly choice and the most common framing material under every kind of deck. As a walking surface it needs regular cleaning and sealing or staining, and boards can split, cup and splinter as they weather.
Composite decking
Composite boards blend wood fibers and plastic, usually with a protective cap layer. They resist rot and insects, don’t need staining and come in many colors and wood-grain textures. They cost more up front but save years of maintenance.
PVC (cellular) decking
PVC boards contain no wood at all, so they shrug off moisture — a strong choice for docks, lagoon-front decks and spots that stay damp. They’re typically the most expensive option.
The frame and hardware matter most
- A properly flashed and bolted ledger where the deck meets the house
- Footings sized and placed to code
- Stainless or hot-dipped galvanized fasteners and hangers near salt water
- Code-compliant railings and stairs
Replacing boards on a failing frame is money wasted, so we always inspect the structure first. See our deck building and repair services or call (908) 636-9745.
Frequently Asked Questions
How long does a composite deck last?
Quality composite and PVC decking commonly carries long manufacturer warranties, and the boards typically outlast wood by many years with far less maintenance.
Does composite decking get hot in the sun?
Yes, darker composite and PVC boards can get hot in direct summer sun. Lighter colors and shaded layouts help.
What hardware should I use for a deck near the ocean?
Use stainless steel or hot-dipped galvanized fasteners, joist hangers and post bases. Standard hardware corrodes quickly in salt air.
