Services
Finish carpentry services in Quincy, MA.
From a single door to a whole-house trim package or a composite deck refresh, every job gets the same attention to layout, joinery and clean-up.

Finish Carpentry & Interior Trim
Trim that makes a room look finished.
Trim is where a room either looks crisp or looks rushed. We take care with layout, coping and miters so the joints close tight and the lines read straight, ready for paint.

Doors & Door Installation
Doors that swing, latch and close the way they should.
A well-installed door has even gaps, closes without a push and latches on the first try. We hang pre-hung and slab doors, adjust what’s already there and finish the opening with casing that matches the house.

Windows & Window Trim
Windows installed and trimmed out cleanly.
Window installation, plus the interior trim that finishes the opening: extension jambs brought flush, a stool and apron that sit level, and casings that match the rest of the room.

Custom Built-Ins & Shelving
Built for the room, not bought for it.
Built-ins use space that furniture can’t, and they should look like they were always part of the house. We build and install units scribed to your walls and trimmed to match the room.

- Bookcases & wall units
- Custom shelving
- Closet shelving
- Mudroom benches & storage
- Window seats

Deck Finishing
The finish work that makes a deck.
We specialize in the finish side of deck projects: new composite decking, railings, stairs, fascia and trim, plus replacing damaged or rotted components and upgrading decks that are showing their age.
- Composite decking installation
- Deck railings
- Deck stairs
- Fascia & trim
- Rotted board & component replacement
- Deck remodeling & repairs
About framing: our focus is the finish layer, not building decks from the ground up. When a project needs new framing, we can coordinate it through a framing crew so the finish work starts on a solid base.
Flooring Installation
LVP and hardwood floors, installed right.
We install luxury vinyl plank (LVP) and hardwood flooring, along with the transitions, thresholds and baseboard that finish the room. It pairs naturally with trim work, so one crew can take a room from subfloor to final baseboard.
Please note: we install hardwood floors but don’t sand or refinish them.
