Verified record
Two Hingham High School friends, Roger Gallagher and Jack O'Brien, started Impruv Builders in 1978 after Boston University — painting, roofing, cedar siding, decks and trim replacement at first, by the company's own account. Today the company describes itself as a family-run South Shore general contractor doing remodeling, additions and whole-house renovations, owner-operated by Gallagher, with a stated service area covering Hingham, Hull, Scituate, Duxbury, Cohasset and Norwell. For a South Shore homeowner planning an addition or a gut renovation close to home, a shop that says it has worked these towns since 1978 is worth a call. Ask to walk two or three recent projects nearby, and confirm the company's Massachusetts home improvement contractor registration and insurance before you sign.
