InsulateAverage annual energy waste through poor insulation in your zip code
per year — leaking through attic bypasses, rim boards, and crawlspace gaps
R-Value is not a suggestion.
It is the only number your building envelope answers to.
The Department of Energy recommends R-49 to R-60 for attics in climate zones 5–7. The average American home sits at R-11.
Thermal imaging — same house, same January, 11 days apart
Same house.
Same January.
11 days apart.
Every gap sealed.
First visit.
We pass code inspection the first time — or we come back at our cost. That's in writing.
Attic Air Sealing & Insulation
We seal every top-plate bypass, recessed light, and plumbing chase before laying R-49+ blown cellulose or spray foam.
Attic bypasses account for 40% of a home's total air leakage. We close them first.
Crawlspace Encapsulation
Closed-cell foam on the rim board, 20-mil poly barrier on the floor, and conditioned air — your pipes stop sweating, your floors stop being cold.
Moisture control + thermal barrier in one mobilization.
Rim Board & Band Joist
2-inch closed-cell foam seals the most-overlooked thermal bridge in any wood-frame structure. Code-compliant vapor barrier included.
Often missed in energy audits. Never missed by your heating bill.
Dense-Pack Wall Cavities
Drill-and-fill dense-pack cellulose reaches every stud bay in existing walls without removing drywall.
R-3.7 per inch. No demolition. One-day installation on most homes.
Multi-Unit & Commercial
Property managers: we schedule around tenants, document every unit for code files, and invoice by building — not by unit.
Portfolio pricing available for 4+ units. First inspection free.
The bill doesn't lie.
Verified results from homeowners who stopped guessing and started measuring.

"My February gas bill went from $418 to $214. I called them back in April to do the crawlspace."

"They invoiced by building, documented every unit for code files, and never once disrupted a tenant. That's the whole job."

"I've used four insulation subs in ten years. Insulate is the only crew that passed blower door first try — every single time."
