Insulation, Heat Pumps &
Air Sealing in Saco
Saco has everything from Greek Revival homes from the 1820s cotton mill era to beach-community cottages at Kinney Shores that were never designed for a Maine winter. Downtown's multi-family mill worker housing from the 1880s and 1890s has balloon framing and essentially no wall insulation. The suburban rings built in the 1960s and 70s have the more familiar problem: fiberglass batts without air sealing, drafty in January. We serve all of it, just 17 miles from our Westbrook shop.

What We Do for Saco Homeowners
Insulation
Downtown Saco's 1880s multi-family mill worker housing has balloon framing and little to no wall insulation. The Greek Revival homes in the historic district need sensitive dense-pack work that respects historic plaster and clapboards. Beach community cottages at Kinney Shores and Ferry Beach often have uninsulated floor systems sitting above cold air — we address all of it with the right technique for each structure.
Insulation in SacoHeat Pumps
The multi-family downtown housing and the older single-family homes in Saco's neighborhoods rarely have ductwork. Ductless mini-splits are the right tool: one outdoor unit, multiple indoor heads placed where the heat is needed. Beach homes that rely on electric resistance or propane space heaters are ideal candidates — heat pumps are 2-3x more efficient than either.

Balloon-frame downtown housing has continuous wall cavities from foundation to attic that act like chimneys in cold weather. Ice dams on the older downtown homes trace back to attic air leakage: heat escapes, melts roof snow, refreezes at the cold eaves. We use blower door diagnostics to find every pathway, then seal systematically before insulating.

Why Saco Homeowners Choose Horizon Homes
We work across Saco's range of housing types every week — from historic district homes to beach community conversions.
Historic Homes Done Right
Saco's Greek Revival and Federal homes in the historic district require a careful approach: dense-pack cellulose through small exterior holes, no plaster disturbed, no moisture trapping. We've worked in historic Maine buildings for years and know what the building inspector and the historical society both want to see.
Beach Community Conversions
Kinney Shores and Ferry Beach cottages that have been converted to year-round use are some of the most energy-inefficient homes we work on. Floor systems sitting above cold air with no insulation, walls with no vapor barrier, propane space heaters running constantly. The improvement potential is enormous.

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 Saco
Beach Cottage Conversion Slashes Propane Use by 60%
A Saco couple had converted their 1940s Kinney Shores cottage to year-round use a few years prior. The floor system was uninsulated, the walls had never been touched, and they were running through propane at an alarming rate in winter. A blower door test showed over 4,200 CFM50 — extraordinary even for a small house.
We insulated under the floor with spray foam, dense-packed the walls, air-sealed the attic, and installed a cold-climate heat pump to replace the propane. Propane use dropped from 850 gallons to under 340 gallons. The house is now comfortable from October through April for the first time.
