Why Homeowners in Newton, Lexington, and Concord Trust Lumi Construction

Every permit. Every code. Every detail handled.

We hold active CSL and HIC licenses, so you never have to worry about compliance. Your project is protected from day one legally and professionally.

Your family’s safety is never an afterthought.

Lead Safety certified (AL2020011425) and Lift Safety certified (SL181217132) because the people inside your home matter more than the project itself.

You relax. We handle everything.

From architectural blueprints to city permits, inspections to final sign-off we manage every step so you can focus on what matters: enjoying the result.

“Hiring Lumi isn’t just hiring a contractor. It’s partnering with a team that shows up, follows through, and treats your home like it’s our own. We don’t cut corners not on materials, not on safety, not on your trust.”

– Luigy Sacramento, Founder and GC
