Home Performance Services in North Yarmouth, Maine
North Yarmouth is one of Maine's most rural towns within the Portland orbit — large lots, working farms, and a mix of 19th-century farmhouses and Greek Revivals alongside the 1980s and 1990s Colonials that came in when families started moving out from the city for land and schools. No natural gas reaches North Yarmouth, so oil and propane are the only heat sources for most homes, and the older farmhouses on this list are expensive to heat. We serve North Yarmouth, 18 miles from our Westbrook shop.

19th-century farmhouses and Greek Revival homes in North Yarmouth often have fieldstone foundations with no rim joist insulation and empty wall cavities that have never been touched. The 1980s Colonials on larger lots were built to code at the time, but that means R-11 walls and maybe R-19 in the attic — well below what's needed for a Maine winter on five acres. We bring both types of homes up to standard.
Learn MoreNo natural gas in North Yarmouth means oil or propane for almost every home. Cold-climate mini-splits cut heating costs significantly on both fuels, and for the older farmhouses without ductwork, ductless is the right installation approach. One outdoor unit can serve multiple indoor zones — useful in a large farmhouse where the kitchen, living room, and upstairs bedrooms all need independent control.
Learn MoreThe Greek Revival and Cape Cod rooflines common in North Yarmouth are susceptible to ice dams when attic insulation is inadequate. Older farmhouses with fieldstone foundations have extensive air leakage paths through the rim joist and basement ceiling. We seal the whole envelope systematically before insulating, confirmed with blower door testing before and after.

Rural homes on large lots have different energy challenges than a suburban Colonial. We know the difference.
19th-century farmhouses in North Yarmouth were built with timber frames, plaster walls, and no insulation concept at all. They're beautiful and they're expensive to heat. We dense-pack the wall cavities through small exterior holes, seal the attic, and insulate the rim joist — without disturbing historic details or creating moisture problems in the old wall assembly.
Older farmhouses and larger Colonials on North Yarmouth's wooded lots have significant heating loads. The improvement potential is correspondingly large. A comprehensive project can eliminate 400-600 gallons of oil a year, which at current prices is real money every winter going forward.

"Horizon Homes is excellent. They have supported us for a number of projects across insulation and carpentry and I can't recommend them enough. Cody is extremely thoughtful and has supported us over hours on the phone answering questions."
"No more cold floors, no more drafts in the living room. The difference after insulation and air sealing was immediate and dramatic. I wish I had done this years ago. Horizon handled the Efficiency Maine rebate. I didn't have to do a thing."
"The crew was meticulous. They sealed every penetration before blowing in the insulation, explained exactly what they were doing, and left the attic cleaner than they found it. Our heating bill dropped noticeably the very first month."
A North Yarmouth family owned an 1880s post-and-beam farmhouse on four acres that was burning 1,400 gallons of oil a year. The walls were original plaster with no insulation, the attic had a thin layer of old fiberglass batts, and the fieldstone foundation had an open rim joist. The house was drafty throughout every room.
We dense-packed the wall cavities, sealed and insulated the rim joist, and brought the attic to R-49. We then installed a three-zone cold-climate heat pump. Oil consumption dropped to roughly 840 gallons — down 40% — and the heat pump handles all heating load above about 5°F. The family has a backup boiler for the coldest nights but rarely uses it.
