Where mold grows, and what each spot usually costs
- Attic mold Roof leaks, bath fans that vent into the attic, and winter condensation on cold sheathing.
- Basement mold Foundation seepage, high humidity, and finished walls that trap moisture against block.
- Crawl space mold Open vents in humid climates, bare dirt floors, and plumbing leaks nobody sees.
- Bathroom mold Grout and caulk growth from steam, and hidden rot behind tub surrounds.
- HVAC and duct mold Wet evaporator coils, drain pans, and ducts that spread spores through every room.
- Black mold Stachybotrys on wet drywall and paper after a leak that ran for days or weeks.
- Mold after flooding Standing water, Category 3 contamination, and the 24 to 48 hour window before growth starts.
- Mold behind walls Hidden growth from plumbing leaks and window flashing, found by smell before sight.
- Mold around windows Condensation on cold glass, failed flashing, and sills that stay wet all winter.
- Mold in closets and storage Still air against an exterior wall, cardboard, and clothing that holds humidity.
Four services, priced apart
A good quote keeps them separate, and so does the estimate.
All twelve cost guidesInspection
A trained look at the extent and the moisture source. Priced on its own.
Testing
Air and surface samples with lab analysis. Useful for hidden growth and clearance.
Remediation
Containment, removal of affected material, HEPA cleaning, and antimicrobial treatment.
HVAC cleaning
Coils, pans, air handler, and ducts, so the system stops moving spores.
Why the estimate comes first
EPA draws the line at about 10 square feet. Under that, with the moisture source fixed, most homeowners can clean it themselves. Over that, or after a lot of water damage, EPA points to professional guidance. The estimate tells you which side you are on before a truck rolls.
It also separates the two things people confuse. An inspection finds the extent and the moisture source and runs $300 to $800. Remediation removes the growth and runs per square foot. A company that quotes the second without doing the first is guessing.
Under about 10 sq ft
Usually a homeowner job once the leak is fixed. The flow says so and shows the professional price anyway.
Over 10 sq ft, or after a water event
Professional scope. Containment, removal, HEPA cleaning, and a dry moisture source before the walls close.
Hidden or smelled, not seen
Inspection first. The band includes it, and the remediation line stays open until the extent is known.

Questions people ask
How accurate is the estimate?
It is a planning band, not a quote. Every number traces to a published 2026 source such as This Old House, Fixr, HomeWyse, and Angi, and the sources are listed on each cost page. A remediation company confirms the scope on site, and that visit is the only firm price.
Is the estimate free?
Yes. The band appears on screen before you share any contact details. Sending it to the featured remediation company is also free and carries no obligation.
Who gets my details?
One featured remediation company for your area, plus us. There is no bidding list and your details are never sold.
What if the area is small?
EPA says areas under about 10 square feet are usually a homeowner job once the moisture source is fixed. The flow tells you when that applies and still shows what a professional would charge.
Do you cover my city?
The estimate works anywhere in the United States. Featured remediation companies are added city by city, starting with the South Carolina Upstate. Where no company has claimed a city yet, we forward the request by hand.
