Home performance in Kennebunk

Kennebunk 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

Coastal houses in Kennebunk have their own list

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.

  • Crawl spaces and floors over unheated space
  • Basements never designed to be inside the envelope
  • Moisture checked before anything gets closed in
  • Ventilation sized for a house now lived in year-round

From a Kennebunk customer

Shaunee, Bob and the installation crew Trey and his team all did a really wonderful and professional job. Would highly recommend them for their Energy Maine audits and insulation work.

Kennebunk questions

Rebate rules change, so confirm the current detail with us before committing to work.

Do you serve Kennebunk, Maine?

Yes. HeatMizer is based at 1550 Main St in Sanford and covers Kennebunk along with the rest of York County for home energy audits, insulation, air sealing, heat pump installation and service, and ventilation work.

What rebates can a Kennebunk homeowner get?

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 Kennebunk 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.

Where should a Kennebunk project start?

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.
