Building a deck in Osterville
Osterville is one of the seven villages of Barnstable, on the south side of town along Nantucket Sound, with its center on Main Street, the Wianno shore on East Bay, and Oyster Harbors, a gated community on Grand Island reached over a drawbridge.
Osterville meets West Bay, East Bay, and Nantucket Sound. Close to the bays and the sound, 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.
Waterfront lots on West Bay, East Bay, and the sound often fall in flood zones or inside the Conservation Commission’s 100-foot buffer, so a deck there starts with the flood map and that review. In Oyster Harbors, we also confirm gate access and work hours before we schedule.
Osterville homes range from the streets near Main Street to the Wianno shore and the island lots of Oyster Harbors. On an older house, replacing a deck is the time to check the ledger and the flashing, where a deck attached decades ago tends to fail first.

“Mussato Building Group has been a loyal and trusted partner of ours for over ten years and one hundred projects. Their professionalism and quality of work are second to none. We look forward to working with them far into the future.”

Deck Builder in Osterville: FAQ
Do I need a permit for a deck in Osterville?
Yes, in most cases. A new or rebuilt deck needs a building permit from the Barnstable Building Department. If the lot is near a wetland, dune, or the shore, the Barnstable Conservation Commission reviews it too. We handle the paperwork.
Do you build decks in Osterville village and Wianno?
Yes. We build and replace decks all over Osterville, including Osterville village, Wianno, and Oyster Harbors. Our base in South Yarmouth is about 12 miles away.
Do you build decks in Oyster Harbors and Wianno?
Yes. Both are part of Osterville, so the Town of Barnstable issues the permit. For Oyster Harbors, which is gated, we confirm access and work hours before we schedule.
What decking holds up best in Osterville?
On a lot close to the bays and the sound, 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 Osterville 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.
