Home Performance Services in Cumberland, Maine
Cumberland has two distinct characters. Cumberland Foreside sits on Casco Bay with coastal exposure, larger homes, and wind that drives cold air through any gap in the envelope. Cumberland Center and the western parts of town are rural and agricultural, with 19th-century farmhouses and Greek Revivals on large lots. Neither side of town has natural gas — oil and propane are the default fuels. The homes are bigger than average, which means heating loads are larger and the savings from a well-executed weatherization project are proportionally higher. Just 12 miles from our Westbrook shop.

Cumberland's older farmhouses and Greek Revivals were built well before modern insulation standards. Wide-board sheathing, original plaster walls, and large attic spaces with minimal coverage are common. The coastal homes on the Foreside have wind-driven infiltration as an added load. Newer construction from the 1980s and 90s has standard platform framing but often has settled batts and uninsulated rim joists. We assess each home's existing conditions, dense-pack where needed without removing plaster, and bring attic coverage to R-49.
Learn MoreWith no gas available in Cumberland, the choice is between oil, propane, and electricity. Heat pumps running on electricity are considerably less expensive to operate at current fuel prices. The larger homes on the Foreside often have multiple zones and high heating loads — a multi-head mini-split system or a ducted heat pump can handle these well. The rural farmhouses in Cumberland Center benefit from ductless systems that don't require modifying the existing structure. Efficiency Maine rebates make the investment significantly more manageable.
Learn MoreCoastal wind exposure at Cumberland Foreside means leaks that would be a minor annoyance inland become a real comfort problem. The older farmhouses in Cumberland Center often have open attic bypasses through partition walls, unsealed top plates, and gaps around chimneys. We use blower door diagnostics to find and seal every significant leak path before adding insulation. This sequence — air seal first, then insulate — is what delivers lasting results instead of incremental improvement.

From Casco Bay to Cumberland Center, we know what these homes need.
Homes on Cumberland Foreside face prevailing winds off Casco Bay. In older construction, that wind finds every gap — around windows, through wall cavities, at the rim joist. Blower door testing quantifies exactly how much air is moving and where it's coming from. We seal the leaks that matter most before addressing insulation levels.
The 19th-century farmhouses in Cumberland Center and the western part of town were built to last, but not to be efficient by modern standards. Wide-board walls and original attic construction can be improved significantly without gutting the structure. Dense-pack cellulose in the walls and air-sealed attic insulation typically reduce heating loads by 25 to 40% in these homes.

"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 Cumberland Foreside homeowner in a 2,400 sq. ft. 1920s home was spending over $5,800 per year on oil. The coastal location meant wind-driven infiltration was a significant contributor to heat loss. Blower door testing found 3,600 CFM50 of air leakage — high even for a home of that age and size. The attic had inconsistent coverage from multiple previous attempts, and the wall cavities were uninsulated.
We systematically air sealed the attic floor, brought insulation to R-49, and dense-packed the walls. Heating costs dropped to around $3,600 that winter. The following spring the homeowner added a three-zone heat pump system, which now handles the majority of the heating load.
