Kennebunkport, York County
Kennebunkport is on the southern Maine coast, and we serve it from our shop in Sanford. Coastal houses here run the full range from tight newer builds to summer places that were never meant to hold heat in February.
Everything we do starts the same way: measure the house, rank the problems, then fix them in the order that actually pays back. Insulation, air leakage, heating and ventilation are one system, and changing one changes the others.

What we usually find
A lot of the stock between Kittery and Saco started as a summer place and became a year-round house one renovation at a time. That history shows up underneath: shallow crawl spaces, piers, uninsulated floors over vented space, and a basement that was never meant to be part of the heated envelope.
Those are fixable, but the order matters and so does moisture. We check for it before we close anything in, because insulating a damp crawl space without dealing with the water first is how you turn a cold floor into a rotten one.
The same services, the same crew and the same certifications across all of York County.

Two to three hours with a blower door and an infrared camera, and initial findings the same day.

Spray foam, blown-in cellulose and dense-pack, with the air sealing that makes any of it work.

Ductless mini-splits, heat pump water heaters and the ventilation a tightened house needs.

At least 40 percent for year-round Maine residents, up to 80 percent by income. We file it for you.
Rebate rules change, so confirm the current detail with us before committing to work.
Yes. HeatMizer is based at 1550 Main St in Sanford and covers Kennebunkport along with the rest of York County for home energy audits, insulation, air sealing, heat pump installation and service, and ventilation work.
Year-round Maine residents automatically qualify for at least a 40 percent Efficiency Maine rebate on eligible upgrades, and up to 80 percent depending on income and household size. That residency test matters more in Kennebunkport than inland, because a seasonal or second home is treated differently. Call and we will tell you which side of the line a particular property falls on before you commit to anything.
With an audit, unless you already know exactly what you need. It takes two to three hours, you get initial findings the same day, and it produces the documented pre-project conditions that Efficiency Maine requires. It also tells you whether the attic or the heating system is the better place to spend first.
