Carvalho Construction is a one-person, Quincy-based exterior and carpentry contractor run by John Carvalho, who says he graduated from Assabet Valley Regional Technical High School's carpentry program in 1995, worked for remodeling companies in the Middlesex area, and has run his own business since 2013. The company's own description centers on roofing, siding, gutters, doors and windows, with bathroom and kitchen work also offered, and its Houzz profile lists the same core services — roof replacement, window replacement, door replacement, gutter and roof cleaning. There isn't yet a customer review on file anywhere to say how the work has actually gone. One thing worth asking about directly: the company's Houzz listing shows a different phone number and a New Bedford-area service area than its own website, which is based in Quincy and says it covers the South Shore and Cape Cod — worth confirming which contact and coverage area is current before reaching out. Anyone considering Carvalho Construction for exterior or carpentry work should treat this as an owner-operated shop with over a decade of stated experience but no independent track record to check yet, and should ask for references and clarify the correct contact details up front.
