Your unfinished basement is already paid for. We turn that square footage into livable space — a home office, a guest suite, a gym, a playroom, or anything else your family needs, fully permitted and built to code.
"My finished basement started getting damp after a year."
Moisture is the number one enemy of a finished basement in New England. Before we frame a single wall, we assess drainage, grading, and existing waterproofing.
"I did not realize I needed a permit for a basement."
Finished basements require permits in Massachusetts and New Hampshire when they involve electrical, plumbing, egress windows, or HVAC changes. We handle all permits.
"The ceiling ended up too low and it feels like a cave."
Ceiling height is determined by existing conditions. We plan the layout around these constraints before framing begins, maximizing livable height and designing around obstacles.
At Lumi, we built our process around fixing exactly these problems. Here's how we work.
Not generic promises. Specific reasons backed by real results.
We do not start finishing a basement until we know it is dry. We assess existing waterproofing, drainage conditions, and any signs of previous moisture intrusion. If we find an issue, we tell you.
Bedrooms in a basement require egress windows under MA building code. We identify requirements during the design phase and include all code compliance work in our scope.
We route ductwork, pipes, and beams to maximize your ceiling height before framing begins. The result is a space that feels like living space, not a basement.
No confusion. No surprises. Just a clear path from first call to finished project.
We inspect your existing basement, check moisture conditions, review ceiling height and mechanical constraints, and discuss your goals for the space.
We produce layout drawings, file all required permits, and provide a fully itemized quote before any work begins.
Framing, insulation, electrical, drywall, flooring, and finish work all completed by our team. You receive a walkthrough and one-year warranty at completion.
"I cannot say enough about the Lumi team! They literally saved us from the nightmare left behind by a previous contractor. From the beginning to the end, all went smoothly. I was impressed with the professionalism, attention to detail, and the time spent working through difficulties. This team worked from sun up to sun down. They cleaned up every evening before leaving the property. I wish I could rate them a 10 because a 5 does not do this team justice. The Lumi team was AMAZING!"
"Five stars for Lumi Construction! They transformed our outdoor space by replacing and expanding our deck, and upgrading our vinyl fence to sleek black aluminum. From start to finish, their professionalism ensured the project was completed to perfection. Highly recommend them to anyone in need of a reliable contractor!"
"Thank you Luigi and team Lumi for the high quality work and excellent service on the Attic Finish project. You came to us with a competitive price, worked with us to match it with our budget and delivered everything within the contract, on time. We are highly satisfied and would definitely recommend you to our friends and family."
