Lebanon, York County
Lebanon is one of the inland York County towns we work in most, and it is a short run from our shop in Sanford. Older stock out this way often has little or no wall insulation and an attic plane full of gaps, which is why we test before we quote rather than after.
Everything we do starts the same way: measure the house, rank the problems, then fix them in the order that actually pays back. Insulation, air leakage, heating and ventilation are one system, and changing one changes the others.

What we usually find
Inland York County housing stock runs to capes, farmhouses and ranches, a lot of it built before anyone insulated a wall on purpose. The heat loss is rarely where people expect it. It is almost never the windows.
In a house like that the attic plane does most of the damage. Warm air leaves around the chimney, the plumbing stack, the wiring penetrations and the top plates, and the insulation sitting on top of those gaps does nothing to stop it. Seal the plane first, then insulate it, and the same furnace suddenly keeps up.
The same services, the same crew and the same certifications across all of York County.

Two to three hours with a blower door and an infrared camera, and initial findings the same day.

Spray foam, blown-in cellulose and dense-pack, with the air sealing that makes any of it work.

Ductless mini-splits, heat pump water heaters and the ventilation a tightened house needs.

With an audit, unless you already know exactly what you need. It takes two to three hours, you get initial findings the same day, and it produces the documented pre-project conditions that Efficiency Maine requires. It also tells you whether the attic or the heating system is the better place to spend first.
