Deck Builder on Cape Cod
Mussato Building Group is a deck builder and general contractor based in Yarmouth, MA. We design, permit, and build new decks, and replace worn-out ones, in all 15 towns on Cape Cod, from Bourne and Falmouth to Provincetown. We are a family-owned general contractor founded in 2004, with more than 100 projects completed and a 5.0 rating from 21 Google reviews.
Every deck is overseen by Joe Mussato and built by the same team that frames and finishes our custom homes, so the structure under the boards gets the same care as the parts you see.

New decks
We build decks off the back of the house, wraparound decks, second-story decks with stairs, and platforms framed to carry a hot tub. Composite boards with composite or PVC railings are the low-maintenance choice near salt air, and we also build in cedar and pressure-treated wood.
Deck replacement
If your deck is soft, loose, or just worn out, we tear it out, check the ledger, posts, and footings, and rebuild. When the existing footings are sound and meet current code, we can reuse them. When they are not, we replace them, so the new deck does not sit on an old problem.

Built for Cape Cod weather
Salt air and hardware
Near the water, standard fasteners rust. We use hot-dip galvanized or stainless steel connectors and screws wherever salt air reaches the deck.
Footings below the frost line
Every post sits on a footing set below the frost depth the Massachusetts building code requires, so the deck does not heave in winter.
Ledger and flashing
Where the deck meets the house, the ledger is bolted and flashed so water stays out of your home’s framing. A poorly flashed ledger is one of the most common reasons old decks rot.
Flood zones and the shoreline
If the house is in a FEMA flood zone or within 100 feet of a wetland, dune, or coastal bank, the footings, the framing, and the paperwork change. We check the flood map and the Conservation Commission rules before we design.
Historic districts
In the Old King’s Highway Regional Historic District along Route 6A, a deck that can be seen from the street needs a certificate from the town’s OKH committee. We build that step into the schedule.
“As the General Manager of Pretty Picky Properties I’ve had the pleasure of working with Joe and his team for nearly 10 years. Joe’s carpentry skills are unmatched. He’s always respectful, finishes on time, priced well, and transparent from start to finish. You will not regret hiring Mussato Building Group.”
Our Process
Site Visit
We look at the house, the grade, the existing deck if there is one, and how you want to use the space, then measure.
Design & Permits
You get a layout, a material choice, and a written estimate. We draw the plans and file for the building permit and any town approvals.
Footings & Framing
Footings, posts, beams, and joists go in to code, with the ledger flashed and the hardware rated for the location.
Boards, Rails & Inspection
Decking, railings, and stairs are installed, the town inspects, and we walk the finished deck with you.

Deck Builder FAQ
Do I need a permit to build a deck on Cape Cod?
In most cases, yes. A new deck, or a replacement that rebuilds the structure, needs a building permit from the town. Decks near wetlands, dunes, or the shore may also need Conservation Commission approval, and decks visible from the street in the Old King’s Highway district need a historic certificate. We prepare the drawings and handle the applications.
Composite or wood: which deck holds up better near the ocean?
Composite and PVC boards do not need sanding or staining and stand up well to sun and salt air, which is why they are popular on Cape Cod. Cedar and pressure-treated wood cost less up front and look natural, but they need regular cleaning and a fresh coat of stain. Whichever you choose, the framing underneath is what decides how long the deck lasts.
Can a deck hold a hot tub?
Yes, if it is framed for it. A filled hot tub is a heavy, concentrated load, so the joists, beams, and footings under it are sized for that weight from the start. The deck we built in Bourne has a hot tub platform designed this way.
How much does a new deck cost?
It depends on the size, the height off the ground, the decking and railing material, the stairs, and the site. After a site visit we give you a free written estimate with the scope spelled out, so you can compare it line by line.
Which towns do you build decks in?
All 15 towns of Barnstable County: Barnstable, Bourne, Brewster, Chatham, Dennis, Eastham, Falmouth, Harwich, Mashpee, Orleans, Provincetown, Sandwich, Truro, Wellfleet, and Yarmouth.
