We know you've heard promises before. Here's what makes us actually different.
Our estimates are itemized and straightforward. The number you approve is the number you pay. No surprises mid-project, no last-minute change orders you didn't ask for. Transparency isn't a feature here, it's how we do business.
From the moment we break ground to the final walkthrough, you hear from us regularly. We don't disappear between milestones. If something changes, you know immediately, not after it's already been done.
Start dates aren't suggestions at Lumi. We respect your time, your schedule, and the fact that you planned around our arrival. Our crews arrive when promised and work until the job is complete.
Every installation we perform is covered by a full one-year craftsmanship warranty. If something isn't right after we leave, we come back and make it right. No questions asked.
Our carpenters, framers, and tilers are Lumi employees, not strangers we call when a job comes in. That means consistent quality, personal accountability, and a team that takes pride in every detail.
Permits, inspections, zoning requirements, we've navigated them in every city and town we serve. You never need to set foot in city hall. We file correctly the first time, every time.
"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.

We are highly satisfied and would definitely recommend you to our friends and family."
