For Homeowners
Cold rooms and high heating bills are not normal. They're fixable.
Home insulation and air sealing for Maine and New Hampshire homeowners.
Your home is losing heat right now — through the attic, walls, foundation, and gaps you cannot see. We find exactly where. Then our crew fixes it. Free estimate, no audit required, your rebate handled.
If any of this sounds like your house, we can help.
These are the problems we fix every day for homeowners across Maine and New Hampshire.
Rooms that never warm up
Part of your house stays cold no matter how high you turn the heat. Other rooms are fine. That is not a mystery — it is air leakage or missing insulation in one specific area. We find it.
Heating bills that keep climbing
Every winter costs more than the last. The house is working against your heating system. More fuel, same result. That changes when the envelope is sealed.
Drafts you can feel but cannot find
Cold air moves through the house and you cannot locate the source. A blower door test pressurizes the home and shows us every leak within an hour.
Ice dams on the roof
Ice dams form when heat escapes through the roof, melts snow, and the water refreezes at the cold eave. It is not a roofing problem. It is a heat loss problem. We fix the cause.
Moisture or musty smell
Air leaks carry humidity from the living space into walls and attics. That moisture becomes mold and rot over time. Sealing the air pathway is the fix — not a dehumidifier.
Furnace that runs constantly
A heating system that never cycles off is not oversized — your home cannot hold the heat it produces. The furnace is doing its job. The house is not.
We have walked through hundreds of Maine and New Hampshire homes dealing with exactly what you just read. The problem is almost never the furnace. It is almost never the windows. It is almost always the insulation and the air sealing — and it is almost always fixable in a single day.

What we install and why it matters.
Insulation
The most common fix. Spray foam, cellulose, fiberglass, and mineral wool — installed in the right location for the right reason. We do not apply one product everywhere. We use what the space actually needs.

Insulation slows heat transfer. Air sealing stops air from bypassing the insulation entirely. Without both, your insulation is performing at half its rated value. We seal first.
Learn moreEnergy Audits
If you want the full diagnostic picture before we recommend anything, we offer a complete blower door test and thermal imaging assessment. Some homes benefit from it. Most do not need it before getting a quote.
Learn moreHeat Pumps
Once your home holds heat properly, a heat pump is the most efficient way to generate it. We install and configure heat pumps and handle the Efficiency Maine rebate — often the single largest rebate available.

"They found air leaks we had no idea existed. Our heating bill dropped 30% that first winter. The crew was fast and clean — they left the place better than they found it."

"I expected to spend weeks dealing with rebate paperwork. They handled everything. The check showed up in six weeks. Couldn't have been easier."
David R.

"We had three companies look at our drafty sunroom. SGH was the only one who actually tested it with a blower door. Night and day difference after the work."

Imagine this time next winter: the cold room in your house is finally comfortable. You open your heating bill and it is noticeably lower than last year. Your furnace cycles off the way it is supposed to. You are not thinking about any of this because there is nothing left to think about. That is what properly insulated and air-sealed homes feel like. That is what we do.
Questions homeowners ask before calling us.
Existing insulation degrades over time, compresses, and develops gaps. More importantly, insulation does not stop air movement — it only slows heat transfer. If your home has air leaks alongside the insulation, conditioned air escapes and outside air enters regardless of how much insulation is present. The combination of air sealing and insulation is what makes a home perform. One without the other rarely solves the problem completely.
