CORNERSTONE GENERAL CONTRACTORS, LLC

Cornerstone General Contractors is a Dorchester Center outfit that takes on whole-house work — additions and extensions, kitchens and baths, basements, decks and porches, garages, and new construction — across a wide Greater Boston service area on its Houzz profile. Houzz lists two licence numbers for the company, HIC #166435 and CS #102149; both are worth checking against the Massachusetts register before you sign. For an addition or a gut remodel, ask for recent references you can call, and put the scope, the schedule and the payment terms in writing before work starts.
