Replacing a deck in Harwich
Harwich stretches from its Nantucket Sound beaches and harbors north to the ponds and cranberry bogs around Pleasant Lake.
Decks close to the sound and the harbors wear out faster: salt air corrodes the hardware, and sun and wind break down the boards. When we replace a deck in Harwich, we start underneath, with the footings and the ledger, and rebuild with corrosion-resistant hardware and, if you want, boards that never need staining.
Homes near Nantucket Sound in Harwich Port and West Harwich often sit in flood zones, while lots up around Pleasant Lake are wooded and farther from salt air.

“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 Harwich
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Harwich 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.
- 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 Harwich: FAQ
Do I need a permit to replace a deck in Harwich?
Usually, yes. Rebuilding the structure needs a building permit from the Harwich Building Department, and the new deck has to meet the current code. Near a wetland, dune, or the shore, the Harwich Conservation Commission reviews it too. We handle the paperwork.
Do you replace decks in Harwich Center and Harwich Port?
Yes. We replace and repair decks all over Harwich, including Harwich Center, Harwich Port, West Harwich, East Harwich, North Harwich, South Harwich, and Pleasant Lake. Our base in South Yarmouth is about 7 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 Harwich?
Close to the sound and the harbors, 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.
