JJ. Mathurin

JJ. Mathurin is a one-person finish-carpentry and remodelling business run from a home address on Park Street in Dorchester, and the one thing that can be checked independently checks out: the Massachusetts registry confirms Home Improvement Contractor registration #209744 as active, effective September 2025 and running to September 2027, with John J Mathurin as the responsible person. There is no other public record. No website, no Google Business Profile, no directory listing, no reviews. For a home-based carpenter who works on referral that is ordinary, and it is not a mark against the business — but it does mean the registration is the only outside confirmation of anything. So treat this as a registered contractor you would check the ordinary way: ask for two or three recent references you can call, confirm registration #209744 yourself on the state's Contractor Hub, and get the scope and price in writing before work starts.
