DeSalvo Construction, LLC

DeSalvo Construction is a Chelmsford design-build firm working on additions, remodels and kitchens — residential and commercial — across the Merrimack Valley, Greater Boston and into southern New Hampshire. The site says Tim DeSalvo founded the company in 1984, still owns it, and that clients deal with him directly. Local threads in July 2025 spoke well of the work. On r/nashua, a homeowner said DeSalvo did their roof in 2020 and it came out great. In an r/LowellMA thread the same month, a commenter who said DeSalvo is a friend he used to work with put it plainly: it won't be cheap, but it will be done well without headaches. The same commenter's rule of thumb was that any builder worth hiring is booked at least six months out. Its Massachusetts home improvement contractor registration, #206780, is active on the state registry. A fit for a homeowner planning an addition or a full kitchen who would rather wait for the right crew than take the first available start date. Ask for the start window in writing, ask who runs the site once the job begins, and ask to see a recent addition nearby before you sign.
