Shrewsbury homes and what they need
Shrewsbury mixes older homes near the town center and Lake Quinsigamond with large neighborhoods of mid-century capes and ranches and newer colonials built since the 1980s.
Shrewsbury runs from Lake Quinsigamond and the town center to newer neighborhoods off Route 140 and Route 20, so homes vary from early-1900s lake cottages converted to year-round use to large colonials. Converted cottages often need insulation added where there was none.
Worcester County is the largest county in Massachusetts by area, and it spans hill towns, mill villages and fast-growing suburbs, so housing ages and heating fuels vary a lot from town to town.
