DeSalvo Construction, LLC

What exists on DeSalvo Construction is word of mouth, not a review pile. In a 2025 r/nashua thread someone said the roof DeSalvo put on their house in 2020 came out well. In a 2025 Lowell thread, a commenter answering a request for contractor recommendations named the company — while disclosing that the owner is a friend he used to work with — and framed it as the expensive-but-no-headaches option. The company is a Chelmsford design-build shop doing residential and commercial additions, remodeling and kitchens across the Merrimack Valley, greater Boston and southern New Hampshire. Its Massachusetts home improvement contractor registration, number 206780, is active in the state registry under DeSalvo Construction LLC. The site says Tim DeSalvo founded the firm and that clients deal with him directly; it also gives two different vintages for the business — established in 1984 in one line, more than 28 years in another. One thing to check yourself: the BuildZoom profile carrying the company's Chelmsford address lists a phone that is not the company's own and shows sample building permits on Cape Cod, so treat that permit history as unconfirmed rather than as this firm's portfolio. For an addition or a whole-room remodel in the Merrimack Valley this is a registered, owner-run firm with a long-standing local name — but the public record behind it is two Reddit comments and an awards listing. Ask for recent addresses you can drive past, references from the last year, and a written scope with allowances before you sign, and expect a quote at the higher end.
