Deck Building
A deck on Cape Cod lives a harder life than a deck anywhere else in the state. Salt in the air eats standard fasteners from the inside, and the coating on a galvanized screw sold for inland use gives up within a few winters. Then the freeze cycle gets into the checks in the wood and opens them.
The Cape also has a generation of decks that went up in the nineties and early two thousands, and most of them are now past the end of their service life. The boards usually look fine. The framing underneath is where the story is.
Compass Home Group builds and repairs decks for year round residents in Hyannis and Barnstable, and for second home owners in Falmouth, Mashpee, Yarmouth and Dennis who only see the deck a few months a year. Our general contractor services cover the rest of the exterior when the deck turns out not to be the only problem.
New decks in pressure treated wood, cedar, composite and PVC, framed for coastal exposure and wind load. Coastal decks get stainless and hot dip galvanized hardware, because standard fasteners do not survive salt air. Permitted and inspected in your town, not built quietly over a weekend.
Board replacement, joist and railing repair, refastening and rot removal. On a Cape deck the failure almost always starts at the ledger, where flashing was skipped and water has been running behind the board and into the house framing for years. The boards on top are the last thing to go.
Composite decking that resists fading, staining and rot, installed over a properly built frame. Composite is only as good as the framing under it, and the framing is what salt air attacks. A composite surface on a rotting frame buys time, not safety.
Natural cedar decks built for the Cape, where cedar weathers to the silver gray that most homeowners here want anyway. Cedar rewards correct fastening and correct spacing, and it punishes both when they are rushed.
Railings in wood, composite, aluminum and cable, installed to code with the post connections done properly. Railing failures are almost always post connection failures, not railing failures, and they happen when someone leans on a rail at a party.
Before You Hire
The ledger is the board that fastens the deck to the house, and it is where most deck collapses begin. It has to be through bolted or fastened with structural screws, never nailed, and it has to be flashed so water runs off instead of behind it. Ask to see the flashing detail before anyone frames.
Salt air is corrosive, and a fastener rated for inland use will fail on a Cape Cod deck long before the wood does. Coastal work needs stainless or hot dip galvanized hardware rated for the exposure. A builder who cannot name what they are using is guessing with your deck.
A deck is structural work and it needs a town building permit. Decks built quietly over a summer weekend show up years later at closing, when a buyer's attorney asks for a certificate that does not exist. That is a problem you inherit, not one that goes away.
New decking over old framing is the most common shortcut on the Cape. The surface looks new and the structure is still rotting underneath. Before any board goes down, the joists, the posts, the footings and the ledger should be inspected and documented.
Areas We Serve
Full Cape CoverageCanal to Outer Cape
Compass Home Group builds and repairs decks in Hyannis, Barnstable, Yarmouth, Dennis, Mashpee and Falmouth, which is where most of the work sits. We also take deck projects in Sandwich, Bourne, Brewster, Chatham, Harwich, Orleans, Wellfleet and Provincetown, and in Plymouth over the bridge. Coverage runs the full length of Cape Cod, from the canal out to the outer Cape. Deck work runs spring through fall, once the ground has thawed enough for footings, so the calls that come in over the winter are the ones that get the good spots on the schedule.
Frequently Asked Questions
Clear answers about deck permits, coastal materials, structural failures, ledger flashing, and inspecting an existing frame before new decking is installed.
The cost of a custom deck on Cape Cod depends on the size of the structure, the decking material selected, railing style, and the condition of any existing framing being tied into. Those variables are assessed in person, not estimated from a photo or a square-footage formula. Get your scope in writing, line by line.
At the site visit, we assess the existing structure, ground conditions, and access before anything is scoped. That walk determines whether the framing can carry a new deck surface, whether footings need to go deeper for frost, and what the permit application will require. Nothing is priced from a photo or a description alone.
When surface boards show rot but the joists and beams are still structurally sound, resurfacing is the right call. When the framing itself is compromised, a full replacement is the only honest answer. We inspect the structure before recommending a direction, because the wrong call costs more in the end and a surface repair over bad framing fails quickly.
Composite decking resists the moisture cycling and salt air that accelerate wood decay on Cape Cod, and it does not require periodic staining or sealing to hold its appearance. Pressure-treated wood costs less upfront but demands ongoing maintenance to stay structurally sound in a coastal climate. The right choice depends on budget, maintenance preference, and how the deck ties into the house aesthetically.
Most deck projects in Hyannis require a building permit, and the application typically includes a site plan, framing details, and footing specifications. We handle the permit application as part of the scope, so the project moves under the correct license from the start. Work done without a permit creates disclosure problems at the point of sale.
Cable, composite, aluminum, and glass panel systems are all viable railing choices, each with different maintenance demands and sightline effects. The right selection depends on elevation, exposure to salt air, and what the permit inspection requires under the Massachusetts building code. We walk through every option before the scope is written.
Existing footings can carry a new deck frame if they were poured to current depth and the concrete is sound, but that determination requires a physical inspection. When footings are undersized or frost-heaved, replacing them is part of the scope, not a mid-build discovery. Every project carries a 1 year written workmanship warranty on the labor we perform.
We build decks across Cape Cod, including Harwich, Chatham, Brewster, Yarmouth, Dennis, Falmouth, Mashpee, Sandwich, Bourne, Orleans, and Barnstable. The owner holds MA CSL CS122588 · HIC 217100 and is on the job site personally for every project, not a project manager working from a distance.
Deck Consultation
If you are trying to work out whether your deck needs boards, repairs or a full rebuild, that is the right question and it is the normal place to start. We come out, get under the deck, and tell you what is actually going on with the frame. Ivan Junior and the crew work out of 47-4 Warehouse Rd in Hyannis. The consultation and the estimate are free.
