What we see in Plaistow homes
The typical Plaistow home was built between 1950 and 1980, which usually means R-11 fiberglass batts in the walls, a thin layer of batts on the attic floor, no air sealing anywhere, and a rim joist that was never insulated. Ranches, split-levels and garrison colonials from these decades are the bread and butter of our NHSaves work: air seal and top up the attic, foam the rim joist, and the house feels like a different place.
About 60% of owner-occupied homes in Plaistow heat with oil or propane, the most expensive fuels in New England per unit of heat. That is why air sealing and insulation pay back so quickly here, and why a cold-climate heat pump is often the next step: it can carry most of the season at a fraction of the cost of delivered fuel.
