Bathroom Renovation in Grafton, MA

The Grafton 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 Grafton 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. On those homes, containment, HEPA filtration and verified cleaning are built into the job, not billed as an extra. Read our MA Lead Law guide.

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.

Commonwealth Bath Co. works from an office in Shrewsbury and covers Shrewsbury, Westborough, Northborough, Southborough, Grafton, North Grafton, South Grafton, Holden and Leominster. If you are just outside those towns, call and ask. We will tell you straight whether we can take the job.

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 are registered as Massachusetts HIC #211749 and carry $1,000,000 general liability insurance. 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 registration number and certificate of insurance before you sign anything.

Every project is backed by a lifetime workmanship warranty for the original homeowner: defective workmanship is repaired or replaced at no additional cost. It does not cover normal wear and tear, acts of nature, or repairs someone else makes. The full terms are on our warranty page.
