- Square footage of affected framing and subfloor
- Whether contaminated fiberglass batting has to be removed and disposed of
- Treatment method, from HEPA vacuuming and antimicrobial to abrasive soda blasting
- Containment and air filtration requirements when the crawl space connects to living space
- The moisture control work needed afterward, which is usually the larger number

Material quantities are taken off a reference 1,400 square foot crawl space with 150 linear feet of foundation wall, priced at Metro Atlanta supplier list rates. Labour hours are costed against Bureau of Labor Statistics wage data for the Atlanta metropolitan area, where the mean hourly wage was $34.57 in May 2025. Permit fees come from the published schedules of the jurisdictions listed on this site. See the detailed cost guide.
When mold removal is the wrong purchase
If the growth covers less than about ten square feet and the moisture source is already fixed, this is often a homeowner-scale cleaning task rather than a contracted remediation.
