Attic Insulation Cost · NJ, NY, PA
What attic insulation costs, with real numbers.
Insulation is the one job we price by the square foot. Here is what moves the number.
What to know
- New blown-in cellulose at R-38, the depth we recommend, runs $1.68 to $2.28 per square foot installed.
- Removing old, ruined insulation first runs $1.20 to $5.40 per square foot, depending on condition.
- Attic size, the condition of what is up there, and whether removal is needed move the number most.
- A free inspection turns these ranges into one exact price, in writing, before any work starts.
The honest per-square-foot ranges.
Insulation is the one job we price by the square foot, so the ranges below are real, not teasers. Wildlife and cleanup work get priced after inspection instead, because no two of those jobs match.
New blown-in cellulose: $1.68 to $2.28 per square foot
Installed at R-38, the depth we recommend for attics in this climate, roughly a foot of material. On a 1,000 square foot attic, that is $1,680 to $2,280 for the insulation itself.
Removal first, when it is needed: $1.20 to $5.40 per square foot
Dry, clean material at the low end. Insulation that animals soiled or moisture ruined takes sealed equipment and more labor, which is what pushes removal toward the high end.
What never gets priced by the foot
Wildlife removal, sealing entry points, and heavy cleanup depend on what the inspection finds, so those get exact written prices instead of ranges.
What moves your number inside the range.
Two attics with the same footprint can land at different ends of these ranges. Three things explain almost all of the spread.
Square footage and access
The attic floor area multiplies everything, and tight hatches or steep rooflines add handling time that shows up in the labor.
What is already up there
Clean, flat insulation can sometimes stay and get topped up. Soiled, wet, or tunneled material has to come out first, which adds the removal line to the job.
Air sealing comes first
Gaps around pipes, wires, and fixtures get sealed before new material goes in. Skipping it undercuts the whole job, so it is part of the plan, not an upsell.
Why phone quotes for insulation go wrong.
No phone call can price this. Twenty minutes in the attic can.
What a guess over the phone cannot see.
Condition is invisible from the driveway
Whether the old material can stay or has to come out is the single biggest swing in the price, and it cannot be judged without eyes on it.
The low guess grows on job day
A number produced without an inspection gets corrected when the crew opens the hatch, and the correction never goes down.
Problems get buried instead of fixed
Pricing that skips the inspection also skips finding soiled material and open gaps, and new insulation on top hides them for years.
The inspection is free, takes about twenty minutes, and ends the guessing either way.

The ranges above bracket the job. The inspection pins it down, and what you get back is short, specific, and photographed.
A one-page written price
One exact number for your attic, with the finished depth named, so there is nothing to interpret and nothing to renegotiate later.
Photos of your actual attic
You see what we saw: the current depth, the condition, and anything that needs attention before new material goes in.
A price that holds
The written number is the number. If something genuinely unforeseeable turns up, you hear about it before anything changes, not after.
What homeowners say
“They cleaned, vacuumed, disinfected, sealed holes, and completely replaced/added new insulation. They even inspected the exterior of the house and blocked some holes where squirrels could get in (and were, as it turned out).”
Jamey L., NJ
“I needed my attic and crawl space insulation removed due to a large infestation. Mike was by far the best guy for the project. I would call him a rodent detective.”
Marc Z., NJ
“They relocated a mother raccoon and 2 babies that had been living in my attic for quite some time.”
