Building a deck in Sandwich
Sandwich is the oldest town on Cape Cod, settled in 1637, with historic homes along Route 6A and newer neighborhoods in Forestdale.
Sandwich meets Cape Cod Bay at Town Neck and East Sandwich beaches. Close to Cape Cod Bay and the marsh, a deck takes more wind, sun, and salt than one inland, so we use corrosion-resistant hardware and low-maintenance boards where the location calls for it, and we check whether the lot is in a FEMA flood zone before we size the footings.
Town Neck and the marsh behind it put parts of Sandwich in flood zones, while houses on Route 6A sit in the historic district.

“I’ve worked with Joe and his team on several projects and the workmanship is consistently excellent. Their attention to detail and the ease of communication is second to none. Highly recommended.”
Deck permits in Sandwich
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Sandwich Building Department, with footing and framing details on the plans.
- Conservation Commission review if the deck is within 100 feet of a wetland, coastal bank, dune, or salt marsh.
- Flood-zone details on the plans if FEMA maps the lot in an AE or VE zone.
- A certificate from the Sandwich Old King’s Highway committee if the deck is in the historic district along Route 6A and can be seen from a public way.
- New composite, PVC, and wood decks
- Deck replacement and tear-out
- Second-story and multi-level decks
- Stairs, landings, and entry steps
- Composite, PVC, cable, and wood railings
- Hot tub platforms framed for the load
- Footings, ledger flashing, and framing to code
- Permits and town approvals
Deck Builder in Sandwich: FAQ
Do I need a permit for a deck in Sandwich?
Yes, in most cases. A new or rebuilt deck needs a building permit from the Sandwich Building Department, and in the Old King’s Highway district along Route 6A a deck visible from the street also needs an OKH certificate. If the lot is near a wetland, dune, or the shore, the Sandwich Conservation Commission reviews it too. We handle the paperwork.
Do you build decks in Sandwich Village and East Sandwich?
Yes. We build and replace decks all over Sandwich, including Sandwich Village, East Sandwich, and Forestdale. Our base in South Yarmouth is about 20 miles away.
What decking holds up best in Sandwich?
On a lot close to Cape Cod Bay and the marsh, composite or PVC boards with stainless or hot-dip galvanized hardware are the low-maintenance choice. Farther from the water, cedar and pressure-treated wood also work well if you are willing to clean and stain them every few years.
Can you replace an old deck in Sandwich instead of building a new one?
Yes. We remove the old deck, inspect the ledger, posts, and footings, and rebuild on a sound structure. Reusing the footings is possible when they are in good shape and meet current code.
