Your home should keep the heat you paid for.
Maine and New Hampshire's Home Efficiency Experts.
We find exactly where your home loses energy — then our own crews fix it. One company, start to finish.
Most energy companies either audit your home or do the work. We do both. Our BPI Certified Auditors use blower door testing and thermal imaging to find exactly where your home is losing heat. Then our own weatherization crews fix it. No referrals, no coordination on your end — one call, one company, one result.
Everything your home needs to stop losing heat.
We do not sell one product and apply it everywhere. We use the right material for the right location — because that is the only way insulation actually performs.
Insulation
The most common reason a home is cold in Maine is not the furnace — it is missing or inadequate insulation. We install spray foam, cellulose, fiberglass, and mineral wool wherever your home is losing heat.

Get the insulation right the first time. We work directly with builders to spec, install, and document insulation for new homes — on schedule, with zero callbacks.

An insulated home needs an efficient heat source. We install and configure heat pumps that work with your improved building envelope — and handle the Efficiency Maine rebate.

A seamless waterproof coating for foundations, basements, and concrete surfaces. Bonds directly to the substrate. Outlasts paint and epoxy by years.

Why One Company Makes All the Difference
When your energy auditor and insulation crew are the same company, the recommendations are clearer and the work gets done right.
Simplified Green Homes audits your home, prepares a detailed report, and has our own in-house crews complete the work. No handoffs. No subcontractors. No wondering whether the installer understood the audit.
We are BPI-certified, Efficiency Maine registered, and Home Performance with ENERGY STAR contractors. Family-operated and headquartered in Lebanon, ME since 2016, we serve southern Maine (York County and Cumberland County) and the New Hampshire Seacoast (Rockingham and Strafford Counties).
Our core services — insulation, air sealing, cold climate heat pump installation, blower door testing, and energy auditing — are all performed by our own employees. We also handle the Efficiency Maine and NHSaves rebate paperwork as part of every project, from application through reimbursement.
What Our Customers Say

If your home does any of these, we can help.
These are the problems we fix every day. They are not normal. They are fixable.
Rooms that never warm up
No matter how high you set the thermostat, part of your house stays cold. That is not a heating problem. It is an insulation problem.
A heating bill that keeps climbing
Every winter it is higher. Your home is working against your heating system — and you are paying for it.
Cold air you can feel but can't find
You know it is there. Our blower door test finds every leak in about an hour.
Ice dams every winter
That is heat escaping through your roof and refreezing at the eave. We fix the cause — not just the ice.
Moisture, condensation, or musty smell
Air leaks carry moisture into walls and attics. Sealing stops it at the source before it becomes rot or mold.
A furnace that runs constantly
When your home can't hold heat, your furnace never stops. Neither does the bill.
You don't have to live with any of these. One call is how most of our customers started.
