What We Do for Westbrook Homeowners
Insulation
Westbrook's balloon-frame doubles and triple-deckers along Main Street and Cumberland Street often have completely empty wall cavities. These late 1800's and early 1900's mill worker homes need dense-pack cellulose in the walls and attic upgrades. Pride Corner's newer construction can still benefit from attic improvements beyond code.
Insulation in WestbrookHeat Pumps
The older mill housing along Main Street and Cumberland Street rarely has ductwork, making ductless mini-splits a natural fit. Multi-unit doubles and triple-deckers benefit from individual heat pump heads in each unit. Newer homes along the river can supplement existing systems for added efficiency.
Heat pumps in WestbrookAir Sealing
Balloon-frame mill worker homes have unblocked wall cavities that act as chimneys, pulling conditioned air up and out of the house. We seal every attic bypass, rim joist, and penetration using blower door guided diagnostics before insulating.

What Our Customers Say
"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."
Real Results in Westbrook
From $3,200/Year Oil Heat to $1,500/Year with Heat Pumps
A Westbrook family in a 1974 ranch was burning 800 gallons of oil a year with bedrooms 10 degrees colder than the living room. We took a whole-home approach: air sealing and insulation first, then a three-zone Mitsubishi cold-climate heat pump system.
Oil consumption dropped from 800 gallons to roughly 50 gallons (backup only). The heat pumps handled everything down to -12°F. Temperature variation between rooms went from 8-10°F to 2-3°F. And they got air conditioning for the first time.
