Replacing a deck in Dennis
Dennis runs from bay to sound right next to Yarmouth, with five villages and the Bass River as its western border.
Decks close to the bay, the sound, and Bass River wear out faster: salt air corrodes the hardware, and sun and wind break down the boards. When we replace a deck in Dennis, we start underneath, with the footings and the ledger, and rebuild with corrosion-resistant hardware and, if you want, boards that never need staining.
South-side streets in Dennis Port and West Dennis sit low and close to Nantucket Sound and Bass River, where flood zones are common, while the bay side along Route 6A is in the historic district.

“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 permits in Dennis
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Dennis Building Department: a rebuilt deck has to meet the current code.
- 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 Dennis Old King’s Highway committee if the new deck changes what can be seen from a public way in the historic district.
- Tear-out and disposal of the old deck
- Inspection of footings, posts, and ledger
- New framing and ledger flashing where needed
- Composite, PVC, and wood decking
- New railings and stairs
- Board and railing repairs on sound framing
- Hot tub platforms and layout changes
- Permits and inspection
Deck Replacement in Dennis: FAQ
Do I need a permit to replace a deck in Dennis?
Usually, yes. Rebuilding the structure needs a building permit from the Dennis Building Department, and the new deck has to meet the current code. Near a wetland, dune, or the shore, the Dennis Conservation Commission reviews it too. We handle the paperwork.
Do you replace decks in Dennis Village and East Dennis?
Yes. We replace and repair decks all over Dennis, including Dennis Village, East Dennis, South Dennis, West Dennis, and Dennis Port. Our base in South Yarmouth is about 3 miles away.
Repair or replace: how do I know?
Look underneath. If the joists, ledger, and posts are solid and only boards or railings are worn, a repair can work. Soft framing, a rotted ledger, rusted hangers, or footings that moved mean a replacement. We check it for you and put it in writing.
What decking lasts longest in Dennis?
Close to the bay, the sound, and Bass River, composite or PVC boards with stainless or hot-dip galvanized hardware hold up best with the least upkeep. Cedar and pressure-treated wood still work well farther from salt air if you clean and stain them.
