What's actually being remodeled in Andover
Andover is a Merrimack Valley town in Essex County, north of Boston, geographically separate from the Franklin County / Pioneer Valley core of the North Boston branch service area. Housing runs from historic downtown colonials, capes, and antique New England singles around Main Street and the Andover Center National Register district, to mid-century ranches and 1980s–2010s subdivisions across West Andover, Ballardvale, and the Shawsheen Village corridor.

- West Andover and Ballardvale subdivision tub-to-shower conversions in framed alcoves
- Aging-in-place walk-in shower conversions for long-tenure Andover homeowners
Northern MA housing stock and conditions
The Merrimack Valley and north-central Massachusetts are dominated by pre-1940 mill-town housing and 1950s-1970s capes and colonials.
Old framing, undersized bathrooms, and cold exterior wall cavities make insulation and venting part of nearly every full remodel here.
- Exterior-wall insulation work is routinely bundled into bathroom remodels
- Small original bathrooms drive closet-annexation layouts rather than relocations
- Separate trade permits lengthen the inspection sequence relative to other states

How Andover 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.
Directional national figures. Local mix shifts with housing age and water conditions.
