Deck questions from Rhode Island homeowners

There is no single RI price list. The best public benchmark is the 2025 Cost vs. Value report, which puts a 16×20 ft deck in New England at about $20,600 in pressure-treated wood and about $25,800 in composite. Smaller, low decks cost less; tall, multi-level or PVC decks with premium railings cost more. Get at least 2–3 written quotes.

Almost always. Decks are regulated under the Rhode Island State Building Code (RISBC-2, the one- and two-family dwelling code) and permits are issued by your city or town building official. Ask your building office about any exemptions rather than assuming.

Your building official sets this. Published examples: Cumberland's deck sheet calls for piers 40 inches below grade, and Charlestown lists a 3 ft 4 in frost depth. Check your own town's current requirements.

If any part of the work is on a coastal shoreline feature or within 200 feet of one, the RI Coastal Resources Management Council generally requires a Council Assent in addition to your local building permit. CRMC staff can verify shoreline features for your lot.

Composite costs more up front (about $5,200 more on the 2025 New England benchmark deck) but doesn't need staining, and it recouped more at resale in that report (95.8% vs 79.1%). Wood is cheaper but needs regular cleaning and re-staining.

No. We're a free matching service. We share your request with independent local contractors who quote and do the work.

Rhode Island requires contractors to be registered with the Contractors' Registration and Licensing Board (crb.ri.gov), which has a public lookup. Ask for proof of insurance, a written contract and a payment schedule tied to progress.

Many homeowners want decks done by late spring, so builders' calendars fill early. Getting quotes in fall and winter leaves time for design, permits and, near the coast, any CRMC review.

Nothing for homeowners. We may be paid by contractors for introductions. You're never obligated to hire anyone.
