What's actually being remodeled in South Boston
South Boston is the home base of our local provider, so this is the bathroom remodel market we know best. Housing runs from 1890s–1920s triple-deckers along East and West Broadway to converted condos around City Point to newer Seaport-adjacent waterfront units. Bathroom scopes vary dramatically between the older triple-deckers and the newer waterfront condos.
- Triple-decker bathrooms with original plaster and compact second- or third-floor footprints
- Condo conversions and waterfront units with HOA approval and freight-elevator scheduling
- Aging-in-place walk-in shower conversions for long-tenure South Boston homeowners
Greater Boston housing stock and conditions
Eastern Massachusetts has the oldest housing stock in the sample: large volumes of pre-1940 triple-deckers, colonials, and capes across Middlesex, Essex, Norfolk, and Suffolk counties.
Old framing, knob-and-tube remnants, plaster walls, and undersized supply lines mean Boston-area remodels almost always involve trade work beyond the bathroom itself.
- Plaster and knob-and-tube discoveries make contingency budgets of 15-20 percent standard, not optional
- Full gut remodels outnumber partial refreshes because partial work exposes non-code conditions
- Municipal inspection scheduling, not materials, is the top cause of local schedule slip

How South Boston compares with the national picture
The national direction is consistent everywhere: showers replace tubs in secondary baths, curbless entries move from specialty to standard, and ventilation gets specified deliberately instead of by default. What changes locally is how much of that work is triggered by failure versus choice, and how much the same scope costs.
