Lewiston and Auburn have a lot of older housing: century-old multi-family buildings, capes and farmhouses with fieldstone basements, plus newer homes out toward Sabattus, Greene, Minot and Poland. We air-seal and insulate all of it, from the attic down to the rim joist.
The call we get most in Lewiston-Auburn is from someone in an older home whose oil tank empties way too fast and whose upstairs or back rooms never feel warm. Those houses usually have thin or settled attic insulation, dozens of air leaks at the attic floor, and a basement that lets cold air straight in at the rim joist.
In Sabattus, Greene, Minot, Poland and Turner, it's often damp basements and crawl spaces under farmhouses and capes, plus new builds, additions and garages where open walls are the perfect time to spray foam.
Either way, the fix is the same: seal the top and the bottom of the house first, then insulate. That's where the comfort and the savings are.
Stop heat from pouring out through the attic: fewer ice dams, warmer upstairs rooms and a furnace that isn't running all night.

In winter, warm air rises and escapes through the attic, and cold air gets pulled in low through the basement and rim joists to replace it. That's why older homes feel drafty near the floor even when the thermostat is turned up.
Adding more insulation without sealing those leaks only helps so much. Air sealing the attic floor and spraying foam on the rim joists stops the air from moving, and then insulation can do its job. ENERGY STAR estimates homeowners can save an average of 15% on heating and cooling costs by air sealing and insulating attics, floors over crawl spaces and basement rim joists.
Less heat in the attic also means fewer ice dams, which is a big deal on the steep roofs and long winters around the Twin Cities.
From Downtown Lewiston to Turner — we serve all of Lewiston & Auburn and the surrounding area:
Retrofitting insulation in an existing attic or basement usually doesn't need a permit, but new construction and additions are inspected in Lewiston and Auburn, and spray foam in basements and attics may need an ignition or thermal barrier depending on how the space is used. We check what applies and handle it in the quote.
Insulation and air sealing can qualify for Efficiency Maine rebates. We'll show you what you likely qualify for at the quote.
Insulation slows heat, but drafts walk right through it. We seal the leaks at the attic floor, rim joists and foundation first, then insulate.
Closed-cell foam for basements and rim joists, cellulose where it's the better value, open walls sprayed while they're open. Not one product for everything.
