Our Services

Everything Your Home Needs, From One Contractor

Eight construction services delivered by the same in-house crew across Marlborough and all of Massachusetts.

Carpentry

Structural and finish carpentry done by our own crew

Carpentry is the trade this company was built on. Ten years of it, across framing, trim, stairs, built-ins, and the structural repairs nobody else wants to open up. When a carpenter runs the job instead of a salesperson, the details land differently.

Remodeling

Whole-home and single-room remodels, start to finish

A remodel is a sequencing problem as much as a building one. We run it with one crew and one point of contact, so demolition, framing, mechanicals, and finish happen in the right order and the job actually ends.

Addition

New square footage that looks like it was always there

An addition is the most demanding thing a residential builder does: new foundation, new framing tied into old, roof lines that have to resolve honestly, and mechanicals extended from systems sized for a smaller house. We do all of it.

Framing

Straight, square, code-compliant structure

Framing is the one thing you can never fix cheaply later. Every finish in the house inherits whatever the framing did - so we take the extra day to get it plumb, level, and square before anything closes up.

Windows

Replacement and new-construction window installation

A good window installed badly performs worse than a cheap window installed well. The flashing, the shimming, and the air sealing are the job - the unit itself is just a product.

Roofing

Roofs built for New England weather

Roofs here work harder than roofs almost anywhere. Wet snow, ice damming, freeze-thaw, and summer heat all attack the same assembly. We build for that, and we don't leave the ventilation as somebody else's problem.

Doors

Interior and exterior doors hung right

A door is the most-used moving part in a house. Hung properly it swings silently and seals tight for decades; hung badly it drags, drafts, and reminds you every single day.

Decks

Custom decks built to outlast the weather

A deck is a structure, not a surface. Footings below frost, a ledger flashed properly into the house, and guardrails that meet code - get those right and the decking material is the fun part.
