Energy Audits
Know exactly what's wrong before fixing anything.
Home energy audits in Maine and New Hampshire.
Our BPI-certified energy audits use blower door testing and thermal imaging to show you precisely where heat escapes and cold air enters. No guessing. Just data.
What's Included in an Energy Audit
Blower Door Testing
We depressurize your home to measure total air leakage and locate specific leak points. This tells us exactly how leaky your home is — down to a number.
Thermal Imaging
Infrared cameras reveal temperature differences in walls, ceilings, and floors — showing missing insulation and hidden air leaks you'd never find otherwise.
Combustion Safety Testing
We test furnaces, water heaters, and other combustion appliances to ensure they vent safely — especially important in tighter homes.
Written Report
A clear, prioritized list of improvements with estimated costs, expected savings, and rebate eligibility. No jargon, no upselling.
Why the Audit Comes First
Most homeowners know they have energy problems — high bills, cold rooms, ice dams. But without an audit, you're guessing at solutions.
You might insulate the attic when the real problem is air leakage in the basement. You might replace windows when the walls have no insulation.
An energy audit gives you the full picture. It tells you what to fix first, what will save the most money, and what rebates you qualify for.
Thermostat upgrades
As part of a home energy assessment, we identify whether your current thermostat is limiting system performance. Smart and programmable thermostat installation is available as an add-on to any energy audit or heat pump project. Ask us during your consultation.
After your audit, our crew can handle insulation, air sealing, heat pumps, and full weatherization — all under one roof. Rebates are available for most projects.
What happened after homeowners called us.
"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."

"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."
