Lumar Construction

Lumar Construction, working out of Chelsea, is built around concrete — the Better Business Bureau's profile for the company (registered as Lasa & Aaf LLC) specializes it in foundations, driveways and sidewalks. Its own website casts a wider net, adding kitchen and bathroom remodels, decks and patios, finish carpentry, home additions and commercial cleaning, with Chelsea as its stated service area. The company is young — it started in December 2021 and has carried BBB accreditation only since October 2025 — so there isn't much written history yet. The one review on file, posted to BBB, praises the company's communication, craftsmanship and professionalism on a home renovation job, and the BBB profile itself carries an A+ grade. BBB lists two different Massachusetts home-improvement contractor registration numbers for the company, neither verified against the state registry here — worth confirming which one covers your project before signing anything. With so little written history, Lumar reads more like a promising newcomer than a proven contractor — a reasonable pick for a concrete driveway, sidewalk or foundation job in Chelsea, but worth asking for references on anything bigger, like a kitchen or bath remodel.
