Bathroom Renovation in Sudbury, MA

The Sudbury building department requires permits for plumbing relocation, electrical changes and any structural work such as moving a wall or enlarging the footprint. Massachusetts treats plumbing and electrical as separate permits from the building permit, and each needs its own inspection. Purely cosmetic work — tile, vanity swap, fixture replacement with no pipe moves — usually does not. We pull every permit, coordinate the inspections and hand you the closed permit card at completion. That closed card matters at resale and for your homeowner's insurance.

Massachusetts has the oldest housing stock in the country, so this comes up on most Sudbury projects. Any home built before 1978 falls under the EPA Renovation, Repair and Painting rule, and Massachusetts layers its own Lead Law on top for homes with children under six. We are an EPA Lead-Safe Certified Firm — that means containment, HEPA filtration and verified cleaning are built into the job, not billed as an extra.

Our backlog typically runs 6 to 10 weeks from signed contract to crew start. If you have a hard deadline — a relative moving in, a closing date, a rental turnover — say so at the estimate stage and we will sequence around it where we can.

Yes. Commonwealth Bath Co. works throughout Middlesex County from our Shrewsbury shop, and Sudbury is inside our regular route. No trip charges anywhere in Middlesex County.

A standard hall bath gut and rebuild runs 3 to 4 weeks. A master bath with relocated plumbing runs 4 to 6 weeks. A tub-to-shower conversion on its own is 2 to 3 weeks, and a shower-only tile rebuild including frameless glass is about the same. The clock starts the day the permit is in hand, not the day you sign.

Yes. We carry MA Home Improvement Contractor Reg. #187432 and MA Construction Supervisor License CS-105118, plus $2,000,000 General Liability and full workers' compensation. Massachusetts registration also means your project is covered by the state Home Improvement Contractor Guaranty Fund — something you lose entirely if you hire an unregistered contractor. We hand over the license numbers and certificate of insurance before you sign anything.

All of them. Sudbury sits inside our regular Middlesex County route — ZIP codes 01776. There is no trip charge anywhere in the town.
