Middlesex County homeowners
What people here say.
Full gut on a house older than my grandmother. They ran lead containment the whole time and the final invoice matched the contract to the dollar.
Jennifer M.
Chelmsford, MA
They pulled the building and plumbing permits, everything passed first time, and the closed card was in my hand at the walkthrough.
Tom D.
Lexington, MA
Three quotes and theirs was the only itemized one. No allowances that balloon later. That is why they got the job.

Middlesex County questions
Common questions.
We cover all of Middlesex County from our Shrewsbury shop. Chelmsford, Lexington, Reading, Newton, Framingham, Medford, Woburn, Wakefield and 17 more all sit inside our regular route, with no trip charge anywhere in the county.
Yes, and we file them town by town rather than county-wide — Massachusetts issues building, plumbing and electrical permits separately through each municipality, each with its own inspection. We file all three, schedule the inspectors and close the permit out at completion.
Yes. Commonwealth Bath Co. carries MA Home Improvement Contractor Reg. #187432 and MA Construction Supervisor License CS-105118, valid statewide, plus $2,000,000 General Liability and full workers' compensation. Massachusetts registration also puts your project under the state Home Improvement Contractor Guaranty Fund.
A standard hall bath gut and rebuild runs 3 to 4 weeks. A master bath with relocated plumbing runs 4 to 6 weeks. Tub-to-shower conversions and shower-only rebuilds are 2 to 3 weeks. The clock starts when the permit is in hand.
