What We Do for Gorham Homeowners
Insulation
Gorham's historic farmhouses along rural roads often have rubble stone foundations and zero wall insulation. They need comprehensive work from basement to attic. Newer subdivisions near the village meet code but can still benefit from attic upgrades to R-50. We handle both ends of the spectrum.
Insulation in GorhamHeat Pumps
Gorham's older farmhouses rarely have ductwork, making ductless mini-splits a natural fit. Newer subdivision homes with bonus rooms over garages benefit from a dedicated heat pump head to keep that space comfortable. Gorham sits inland where winters run colder, and cold-climate heat pumps are engineered for exactly these conditions.

Gorham's farmhouses have significant air leakage through rubble stone foundations, balloon-frame walls, and unblocked attic bypasses. Newer builds with bonus rooms over garages leak at the garage-to-house connection. We use blower door testing to find every problem, then seal it before insulating.

Why Gorham Homeowners Choose Horizon Homes
We understand the mix of old and new that defines Gorham's housing market.
Farmhouses & Foundations
Gorham's historic farmhouses along rural roads have rubble stone foundations and zero wall insulation. These homes need comprehensive work: foundation insulation, dense-pack walls, attic air sealing, and blown-in attic insulation. We have extensive experience with this type of construction.
Bonus Rooms & New Builds
Newer subdivisions near the village and USM campus are built to code but commonly have bonus rooms over garages that are uncomfortable year-round. We insulate and air seal these spaces to make them usable. Even code-built attics benefit from upgrades to R-50.

What Our Customers Say
"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."
"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."
