The short answer

Who provides carpentry services on Cape Cod?

Coast Carpentry Home Group is a team of Cape Cod carpenters based at 14 Parker Rd in Osterville. Our custom carpentry services cover structural and rot repair, interior trim and built-ins, exterior trim, door and window installation and the small jobs that other contractors will not take. The carpenters on your project are our own employees, we are licensed and insured in Massachusetts, and we work in all fifteen Barnstable County towns.

What we do

Carpentry is the trade everything else sits on. Here is what it covers for us.

Roofing, siding, kitchens and additions all start with carpenters. These are the jobs people call us for by name.

Rot repair and structural carpentry

Sills, rim joists, corner boards, window casings and deck ledgers rot first in salt air. We cut out the damage, fix the leak that caused it and rebuild with the right lumber and flashing.

Interior trim and finish carpentry

Crown, base, casings, wainscoting and the fillers that make a room read as finished. We match existing profiles in older Capes so repairs disappear.

Built-ins and custom millwork

Window seats, bookcases, mudroom cubbies, pantry walls and islands built to the room, not to a catalog. Low ceilings and out-of-level floors are the normal condition here.

Exterior trim

Rake boards, fascia, frieze, corner boards and window trim in cedar, PVC or fiber cement, flashed so the wall behind them stays dry.

Door and window installation

Entry doors, sliders and replacement windows set plumb, flashed and insulated. Coastal-rated units where the exposure calls for them.

Small jobs and repairs

A sticking door, a soft spot in a floor, a stair tread that moves. No job is too small, and many of our long-term clients started with one.

Built for the Cape

Cape houses are old, damp and rarely square. That is the work.

A carpenter on the Cape spends a lot of time on water damage that did not have to happen. Salt air corrodes fasteners, wind-driven rain finds any unflashed joint, and humidity from June to September keeps wood from ever fully drying. The first thing we do on most repair calls is find where the water came in, because replacing a rotted sill without fixing the leak just schedules the next repair.

The second thing is matching what is there. Antique Capes along Route 6A, Victorian cottages in Hyannis Port and Falmouth Heights, shingle-style houses in Osterville and Chatham all carry trim profiles that nobody stocks anymore. We mill or source matching profiles so a repaired casing looks original, and on 6A homes we keep the Old King's Highway committee in mind on anything visible from the road.

The third is the geometry. Floors drop, ceilings sit at seven and a half feet, and walls bow. Factory cabinets and stock trim assume none of that. Scribing, fillers and a level that gets used every ten minutes are what separate carpentry from installation, and it is why custom carpentry services here are a different job than the same work inland.

Where we work

Carpenters for every Cape town.

One shop in Osterville, carpenters across Barnstable County.

Upper Cape

Bourne, Sandwich, Falmouth and Mashpee. Sandwich has the oldest houses on the Cape and the most antique trim to match. Falmouth's village cottages bring plenty of exterior trim and rot work.

Home renovations in Sandwich →

Mid-Cape

Barnstable's seven villages (Hyannis, Osterville, Centerville, Cotuit, Marstons Mills, West Barnstable, Barnstable Village), Yarmouth and Dennis. Our home turf and where most of our trim, built-in and repair work happens.

General contractor in Yarmouth →

Lower Cape

Harwich, Brewster, Chatham and Orleans. Shingle-style waterfront houses with a lot of exterior trim exposed to the Atlantic.

Outer Cape

Eastham, Wellfleet, Truro and Provincetown. Cottages with low ceilings and tight rooms that want built-ins, and exterior trim that salt gets from both sides.

Serving Cape Cod only. We do not work on Nantucket, Martha's Vineyard or off-Cape. Shop and office: 14 Parker Rd, Osterville, MA 02655.

Questions we get on the first call

What people ask a Cape Cod carpenter.

What carpentry services do you offer on Cape Cod?+
Rot and structural repair, interior trim and finish carpentry, built-ins and custom millwork, exterior trim, door and window installation and small repairs. We are also the carpentry crew behind our own roofing, siding, kitchen, bath and addition work.
Is rot repair common on Cape Cod homes?+
Very. Salt air, humidity and wind-driven rain cause rot in sills, trim, decks and door frames faster than inland. We repair the damage and fix the water entry that caused it, then match the original profile so the repair blends in.
Can you match existing trim in an older house?+
Yes. Matching profiles, moldings and finishes in antique and historic Cape houses is a specialty. We mill or source profiles that are no longer stocked.
Do you take small carpentry jobs?+
Yes. A sticking door, damaged trim, a loose stair tread. Many of our long-term clients started with a small repair.
Are you licensed and insured?+
Yes. Coast Carpentry Home Group is licensed and insured in Massachusetts, and the carpenters on your project are our own employees.
What is the difference between your carpentry page and your trim carpentry page?+
This page covers the full range of custom carpentry services. Our trim carpentry and millwork page goes deeper on crown molding, wainscoting, casings and built-in detail work.
Which towns do your carpenters work in?+
All fifteen towns in Barnstable County, from Bourne to Provincetown, based out of Osterville.
