Insulation, a house that holds its temperature

It usually starts with an upstairs that is always warmer than the downstairs. The hard part is not the work — it is that every insulation company sounds equally sure of itself, and you get one guess. We check licence and insurance before we introduce anyone, and we record the date we checked.

Insulation in short

Residential insulation work breaks into five jobs: attic insulation, wall insulation, crawl space and basement insulation, spray foam application, and air sealing. Air sealing comes first. The EPA's ENERGY STAR program explicitly recommends completing an attic air sealing project before adding attic insulation, because insulation slows heat conduction but does almost nothing to stop air leaking through gaps.

Whole-home insulation runs about $2,000-$7,400 nationally, averaging roughly $4,700 for a 2,000 sq ft home, per Fixr's January 2026 cost data. Blown-in insulation costs about $1.65-$3.80 per square foot installed, and spray foam is the expensive option at roughly $2.75-$6.50 per square foot in new construction and $3.15-$7.50 in existing walls.

Why a pro gets to be on this list

Most sites sell your number to whoever pays the most for it. We check the insulation companies we match you with, and we publish the date we checked so you can hold us to it.

Licence checked

We look up the licence with the issuing state or local authority and record the date we checked it.

Insurance confirmed

General liability and, where it applies, workers’ compensation — confirmed with the carrier, not taken on trust.

Reviews read, not counted

We read the recent negatives as well as the average, and we look at how the pro answered them.

Re-checked, not set and forgotten

A licence that lapses drops the pro out of matching. Every record carries the date it was last verified.

What people say after they’ve hired

Zero reviews. On purpose.

We’d rather show you nothing than show you someone else’s reviews.

Plenty of sites fill this space with reviews scraped from elsewhere, or written for them. We don’t. The first insulation review on this page will come from a homeowner we matched, after their work was finished and paid for.

FAQ

Insulation questions, answered

The questions homeowners ask us most about insulation.

For an uninsulated attic, ENERGY STAR recommends R30 in Zone 1, R49 in Zones 2-3 and R60 in Zones 4-8. With 3-4 inches already there, targets drop to R25, R38 and R49. Floors range from R13 to R38 by zone.
About $2,000-$7,400 whole-home, averaging roughly $4,700 for 2,000 sq ft, per Fixr's January 2026 data. Blown-in runs $1.65-$3.80 per sq ft installed; spray foam runs $2.75-$7.50 per sq ft.
Once fully cured and installed correctly, it is a standard building material. During application it is a chemical hazard - OSHA documents isocyanates as a cause of occupational asthma and eye, nose, throat and skin irritation, and notes some are classified as potential human carcinogens. Stay out of the house for the manufacturer's stated re-occupancy period, and take a bad-cure odor problem seriously because removal runs $1.50-$3.00 per sq ft.
An attic top-up often does within a reasonable period. A $20,000 whole-house foam job usually does not on energy savings alone, given ENERGY STAR's up-to-10% figure for annual bill savings. Run the math against your own utility bills.
The IRS states the Energy Efficient Home Improvement Credit applies to property placed in service before December 31, 2025, so do not assume a 2026 project qualifies. Verify current rules on IRS.gov and check your utility and state programs, which are where most active incentives are.

The wrong insulation hire costs more than the right one.

Insulation is sold by the inch and works by the air seal. Adding depth over an unsealed attic buys you very little. Getting matched takes about a minute, costs nothing, and you can walk away from every quote you receive.
