Turn a damp, unfinished basement into a dry, comfortable room that adds real living space. Moisture, framing, and wiring handled by one crew.

Basement finishing

The Extra Room You Already Own

A finished basement is the cheapest square footage you will ever add, because the walls and roof are already there. Across Somerville and Greater Boston it is how families get a home office, a guest suite, a playroom, or a gym without the cost of an addition.

The catch is that a basement is below grade, so moisture, ceiling height, egress, and wiring all have to be done right. We handle the whole thing with one crew, from the waterproofing under the floor to the paint on the walls, so the finished space is dry, legal, and built to last.

What Basement Finishing Covers

Done in the right order, starting with the water and ending with the finishes.

  • Moisture control first

    Before any framing goes up we deal with water: grading, sump pumps, vapor barriers, and sealing, so the finished space stays dry through a New England spring.

  • Framing and insulation

    Framing that respects your ceiling height and existing systems, with insulation detailed for a below-grade space so the room stays warm and quiet.

  • Egress and safety

    Adding a code-compliant egress window or door where a bedroom or legal living space is planned, so the finish passes inspection and keeps your family safe.

  • In-house electrical

    Lighting, outlets, dedicated circuits, and panel capacity handled by our own licensed crew, wired to code as part of the same job.

  • Full living space build-out

    Family rooms, home offices, gyms, guest suites, playrooms, and wet bars, finished with flooring, trim, and paint that match the rest of the home.

  • Permits and inspection

    We pull the permit with the local building department and coordinate the inspection, so your finished basement is legal square footage, not a gray-area project.

How it works

We pull the permit and handle framing, insulation, electrical, and finishes with one team, so the trades never wait on each other.

04

Inspection and walkthrough

We pass inspection with you and hand over a dry, finished, comfortable space that adds real usable square footage.

Basement Finishing FAQs

Common questions about moisture, ceiling height, egress, and permits.

Often yes, but only after the water is handled. In Greater Boston we see damp basements constantly, and we start every project by fixing grading, drainage, sump pumps, and sealing before a single wall goes up. Finishing over a moisture problem is the most common mistake we get called to redo.
Massachusetts code generally wants about 7 feet of finished height for living space, with some allowance around beams and ducts. Older Somerville and Cambridge homes can be tight, so we measure and lay out the ceiling and mechanicals carefully, and we tell you up front if height is a problem.
If the space will be used as a bedroom or legal living area, code requires a proper egress window or door for escape and rescue. We build the egress opening and window well as part of the project so the finished space passes inspection.
When we do it, yes. We pull the building permit, do the framing, electrical, and egress to code, and coordinate the inspection. That turns your basement into legal, finished square footage that holds up at resale, not an unpermitted room.
Yes. Our licensed in-house crew runs the lighting, outlets, and dedicated circuits and checks that your panel has the capacity, all as part of the same job. We hold MA HIC #217519 and CSL #122193 and are fully insured.
