Mold Removal Cost Calculator

This calculator prices a mold remediation job as separate lines rather than one blended number: treatment by the square foot, containment, HEPA air scrubbing by unit and day, material removal, disposal and clearance testing. You supply every rate, because remediation pricing moves by region, by what is behind the surface and by who does the work, so a national average would be the least reliable figure on the page. The result adds a contingency and shows the cost per square foot, which is the number worth comparing between quotes. Anything much over ten square feet of mold is a job for a professional assessment rather than a form, and the output says so.

Areas In

Square Feet Square Metres

The two per-area rates below are read in the matching unit: dollars per square foot, or dollars per square metre.

Affected Area (sq ft) *

The visible mold plus the surrounding surface that has to be treated.

Remediation Rate ($ per unit of area) *

Cleaning, treatment and labour, per square foot or per square metre to match the choice above. Take it from a quote; this tool has no price list.

Containment Setup ($)

Poly sheeting, zip walls and negative pressure so spores do not move through the house.

HEPA Air Scrubbers (units)

Days Running

Scrubber Rate ($ per unit per day)

Material Removed (sq ft)

Drywall, insulation, carpet and trim that cannot be cleaned and has to come out.

Removal Rate ($ per unit of area)

Disposal and Dumpster ($)

Inspections and Tests

Usually one before the work and one clearance test after it.

Cost per Test ($)

Contingency (%)

Mold jobs grow once the wall is open. A contingency is not padding.
