Attic & Roof Insulation
Most homes lose more heat through the attic than anywhere else. We air seal the attic floor and bring insulation up to modern depth so the heat you pay for stays inside.
Residential Weatherization
Warmer winters. Cooler summers. Lower energy bills.
CoreComfort Energy Solutions insulates, air seals, and weatherizes homes so they hold their temperature instead of leaking it. Less work for your heating system, steadier rooms, smaller bills.

What we do
Weatherization is not one product. It is a set of measures that work together to stop a house from losing the energy you already paid for.
Wall Insulation
Dense-pack cellulose blown into empty exterior wall cavities from the outside. It stops the cold draft that makes rooms feel unusable in January.
Air Sealing
We find and seal the gaps around rim joists, top plates, ducts, and penetrations that quietly leak conditioned air all year long.
Basement & Crawlspace
Insulating and sealing below the living space fixes cold floors, damp air, and the frozen-pipe risk that comes with an uninsulated perimeter.
Ventilation & Indoor Air
A tighter house needs controlled fresh air. We install bath and kitchen ventilation so moisture and stale air have a way out.
Health & Safety Checks
Combustion safety testing, carbon monoxide and smoke alarms, and dryer venting — the work that has to be right before anything else happens.
How it works
Four steps, no surprises. You know the scope and the price before any crew shows up.
Home Assessment
We walk the house with you, measure what is there, and test how much air is leaking. You get a clear picture of where the energy is going.
Scope & Estimate
You receive a written scope listing every measure, quantity, and price. Nothing gets installed that is not on that page.
Installation
Our crew protects the work area, installs the measures, and cleans up. Most homes are finished in one to three days.
Final Walkthrough
We re-test, walk the completed work with you, and leave you the documentation for your records.
