Removing attic insulation costs about $1–$2 per sq. ft., so most homeowners pay $1,000–$3,000 for a typical 1,000–1,600 sq. ft. attic; small attics can come in under $1,000. Rodent-contaminated or hazardous material costs far more, and removal plus new insulation runs $2–$6 per sq. ft. (HomeGuide, HomeAdvisor and Angi data, as of October 2026).

Old attic insulation has to come out when it is soaked from a roof leak, moldy, packed with rodent droppings, or so compressed that topping it up won't help. Removal is also common before air sealing, because contractors need to reach the attic floor to seal leaks around wiring, plumbing and top plates.
This guide covers removal costs by attic size, what contamination and equipment add, and how much it costs to remove and reinsulate in one job. For new insulation prices by type, see our attic insulation cost guide.

Cost breakdown: materials, labor, permits and extras
Line-item estimate for vacuum removal of clean, non-hazardous blown-in insulation from a 1,500 sq. ft. attic. Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Removal labor and vacuum equipment | $1,300–$2,600 | Crew, high-powered insulation vacuum and bagging, about $1–$2 per sq. ft. |
| Attic cleaning after removal | $100–$500 | Final vacuuming of debris and dust from the attic floor |
| Disposal | $0–$0 | Included in most quotes for non-hazardous insulation |
| Contingency (about 10%) | $100–$300 | Hard-to-reach eaves, deeper-than-expected layers |
| Estimated total | $1,500–$3,400 | Before any discounts or rebates |
If the crew finds droppings, mold or vermiculite, the job is re-scoped and priced separately before work continues.
What affects the price
- Attic area. Removal is priced by the attic floor area at about $1–$2 per sq. ft.: roughly $500–$1,000 for 500 sq. ft. and $2,000–$4,000 for 2,000 sq. ft.
- Insulation type. Sources disagree on which is harder: HomeGuide says blown-in removal typically costs more than average, while HomeAdvisor says batts and rolls cost more than blown-in. Spray foam and rock wool cost more to remove than either, and vermiculite must be tested for asbestos first.
- Contamination (rodents, moisture). Rodent droppings, urine and mold turn a removal into a cleanup job: expect $600–$1,000 for cleanup and disinfecting, $150–$600 for rodent removal, and sanitation minimums of $1,500–$3,000. Severely damaged or hazardous insulation can cost $25+ per sq. ft.
- Equipment. Pros use truck-mounted or commercial insulation vacuums, which are built into their per-square-foot price. Labor runs about $35–$85 per hour, and a DIY insulation vacuum rents for $200–$350 per day.
- Disposal. Disposal of ordinary fiberglass or cellulose is usually included. Hazardous material such as asbestos-containing vermiculite has to be handled by licensed abatement contractors and disposed of under state and local rules, at about $10–$25 per sq. ft.
Ways to save
- Ask whether the old insulation really has to go. Dry, clean insulation that is just thin can often stay, with new insulation blown on top.
- Bundle removal, air sealing and new insulation with one contractor; removal plus replacement runs about $2–$6 per sq. ft., and you avoid paying for two setups.
- Fix roof leaks and seal rodent entry points first so you don't pay for a second cleanup.
- Check utility and state energy programs: some insulation rebates cover air sealing and reinsulation done after removal.
- If the insulation is vermiculite, have it tested before anyone disturbs it. If it contains asbestos, the Zonolite Attic Insulation Trust may reimburse up to 55% of qualifying removal costs.
How to get an accurate quote
Get at least three written quotes from insulation or attic-cleaning companies. Give each the same information:
- The attic floor area, how you reach it (hatch or pull-down stairs) and the type and approximate depth of the existing insulation.
- Any signs of rodents, droppings, odors, roof leaks or mold, plus photos if you have them.
- Whether you want new insulation and air sealing in the same job, and your target R-value.
- Ask what is included: disposal fees, sanitizing, sealing of entry points, and whether the price changes if contamination is found.
FAQ
How long does attic insulation removal take?
Most removals of clean insulation take a crew one day. Contaminated attics take longer because of cleanup, disinfecting and sealing, and a full remove-and-reinsulate job can stretch to two days.
Can I remove attic insulation myself?
Clean fiberglass or cellulose can be removed by a homeowner with a rented insulation vacuum ($200–$350 per day), protective gear and a lot of bagging. Leave rodent-contaminated, moldy or vermiculite insulation to professionals.
What if my attic has vermiculite insulation?
Vermiculite may contain asbestos. Don't disturb it: have a sample tested and, if asbestos is present, hire a licensed abatement contractor and follow your state and local rules. See our asbestos removal cost guide for prices.
Does homeowners insurance cover insulation removal?
It may when the damage comes from a sudden covered event, such as a burst pipe or storm-damaged roof. Gradual leaks, wear and rodent infestations are usually excluded, so check your policy and document the damage before removal.
