For Builders
The insulation sub who shows up, gets it right, and hands you the paperwork.
New construction insulation and air sealing for Maine and New Hampshire builders.
Missed schedules, failed blower door tests, and callbacks cost money and reputation. We eliminate all three. Our crew shows up when we say, installs correctly the first time, and delivers every document you need before you ask.

Contact. One crew. No subs.
If you have built in Maine, you have dealt with this.
We built this company around eliminating every one of these.
The sub who does not show up
You scheduled around them. Now your timeline is off, other trades are waiting, and you are making calls that should not be necessary.
A failed blower door after drywall
The walls are closed. The test failed. Now you have a decision that costs real money and delays the project. This is a sequencing problem. We prevent it.
Paperwork that isn't ready for the inspector
Energy code documentation, HERS ratings, Net Zero certification requirements. If your insulation sub does not provide it, you are the one chasing it.
Callbacks on work that should have been done right
Re-mobilizing costs you twice. Installation done correctly the first time at the right stage of the build does not get called back.
We have worked on new construction across Maine and New Hampshire. We know the build sequence. We know what the inspector needs. We know what the blower door target needs to be — and we build our scope around hitting it. When we are your insulation sub, the documentation is ready before you ask.
How we work on a new construction project.
Pre-construction coordination
We review your plans before framing is complete. We confirm the insulation and air sealing strategy, schedule around your build sequence, and flag any details that affect our scope early — when they are easy to address.
Rough framing installation
After framing and rough mechanicals are done, our crew installs spray foam, air sealing, and insulation. We work quickly and cleanly. Other trades are not waiting on us.
Final documentation
We deliver every test result, installation document, and material certification your project requires. Permitting, energy code compliance, HERS rating, Net Zero certification. Done before you ask.
When we're your sub
What you get.
A tight, compliant build. Documentation in hand. A sub you can call again on the next project — and the one after that.
Without the right sub
What you're dealing with.
A failed blower door after drywall is a significant problem. A sub that does not show up on schedule costs you time and trust with your client. We exist to eliminate both.
Services for Builders
Questions from builders.
The insulation and air sealing work has to happen after rough framing and mechanicals are complete but before drywall. That window is the only time to properly seal penetrations, address rim joists, and install spray foam in cavities that will be closed forever. Coming in too early means the work gets disrupted. Coming in after drywall means the air sealing cannot be done properly. We coordinate around your build sequence so the work happens at exactly the right stage.
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."
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."
