Asbestos removal cost per square foot
| What is being removed | Installed price | Good to know |
|---|---|---|
| Popcorn ceiling | $4–$20 | The guides disagree most on this one |
| Floor tile or sheet flooring | $4–$15 | The two guides agree closely |
| Walls and drywall | $7–$14 | The two guides agree closely |
| Attic insulation | $10–$25 | Priced higher than floors, walls and ceilings |
| Siding | $7–$15 | Angi runs much wider than HomeGuide |
| Roofing | $40–$125 | Roofing is the most expensive material to abate |
| HVAC ducts | $35–$55 | Priced by one guide only |
| Encapsulation (sealing instead of removing) | $2–$6 | Sealing the material in place instead of removing it |
HomeGuide and Angi agree closely on every material except siding, where Angi's range is much wider. This Old House puts interior work at $5 to $20 per square foot and exterior work at $50 to $150, which matches the table for interior work and roofing but not for siding, where the guides run well below that. Forbes Home lists a popcorn ceiling at $5 to $10 per square foot for full removal, near the low end of ours. Angi puts the average across all jobs at $2,249, with a range of $462 to $6,100.
Cost by amount of material
| Area | Floor tile | Popcorn ceiling | Walls | Attic insulation |
|---|---|---|---|---|
| 100 sq ft | $400–$1,500 | $400–$2,000 | $700–$1,400 | $1,000–$2,500 |
| 200 sq ft | $800–$3,000 | $800–$4,000 | $1,400–$2,800 | $2,000–$5,000 |
| 500 sq ft | $2,000–$7,500 | $2,000–$10,000 | $3,500–$7,000 | $5,000–$12,500 |
| 1,000 sq ft | $4,000–$15,000 | $4,000–$20,000 | $7,000–$14,000 | $10,000–$25,000 |
What changes the price
- Material. Roofing and ducts cost several times as much per square foot as floor tile or a popcorn ceiling.
- Amount. The total is the per-square-foot price times the area, so a bigger job costs more even when the rate is the same.
- Removal or encapsulation. Sealing the material in place costs less where it is allowed.
- Type of asbestos. Amosite and crocidolite add 5% to 10%.
- Testing and permits. Testing comes first, and a disposal permit is a small fixed fee.
- Rebuilding. New drywall, flooring or insulation after removal is a separate cost.
- Where you live. The calculator adjusts the labor share for your state's wages.
Extras to expect
| Item | Typical cost | When it applies |
|---|---|---|
| Asbestos testing | $250–$850 | Before you hire an abatement company |
| Disposal permit | $50–$100 | Where one is required |
| New drywall | $1.50–$4 per sq ft | After removing walls or a ceiling |
| New flooring | $4–$15 per sq ft | After removing floor tile |
| New attic insulation | $1–$4 per sq ft | After clearing the attic |
Replacing what comes out is covered by popcorn ceiling removal cost, flooring installation cost, drywall cost, insulation cost, siding replacement cost and roof replacement cost. If you find mold along with asbestos, see mold remediation cost. Old ducts are also covered by air duct cleaning cost.
Questions to ask before you hire
- Has the material been tested, and can I see the lab report?
- Is the contractor licensed for asbestos work in my state, and can I see the license?
- Is the quote for removal or encapsulation, and why that choice?
- Does the price include containment, disposal, the permit and clearance testing?
- Who rebuilds the wall, ceiling or floor, and is that in the price?

Where do these prices come from?
They come from 3 published cost pages from 3 publishers, last checked Oct 9, 2026. We report what those pages say and do not invent figures; the table above shows each source.
How does my state change the estimate?
The labor part of the price is scaled by the average wage for the relevant trade in your state, using Bureau of Labor Statistics data. Materials and equipment are not adjusted.
Why might a contractor's quote differ from this estimate?
A quote reflects your specific scope, access, local demand and what the contractor includes. Ask for line items rather than a single total so you can compare bids on the same basis.
