Homes and buildings in Northborough
Northborough's neighborhoods spread out from the town center along Route 20 and Route 135, with older farmhouses and colonials near the center and many larger colonials built from the 1970s onward. Bonus rooms over garages and finished basements are common sources of cold rooms we fix here.
Worcester County homes heated with oil or propane often see the fastest payback from sealing air leaks, because every gallon saved is money that stays in the house.
For homes heated with oil or propane, better insulation means fewer fuel deliveries and a smaller heating bill every month of the winter.
