Selling Your Home

What should I know about selling a home with mold?

Short Answer

You must disclose known mold issues when selling your home in New Jersey. Mold can be a dealbreaker for many buyers, so addressing it before listing is usually the best approach. Small areas of mold can often be remediated for a few hundred dollars. Larger infestations may require professional remediation costing $1,000 to $6,000 or more. After remediation, you should have the property tested to confirm the mold is gone. Full disclosure protects you from legal liability.

Mold is a material defect that must be disclosed to buyers in New Jersey. If you know about a mold problem and do not disclose it, you can be sued after the sale for failure to disclose. The severity of the mold problem determines the best approach. Small areas of mold, such as a patch in a bathroom or around a window, can often be cleaned with a bleach solution and improved ventilation. Larger areas, especially those caused by underlying moisture issues like a leaking roof or plumbing problem, require professional remediation. The remediator will identify and fix the moisture source, remove the mold, and treat the area to prevent regrowth. After remediation, a mold clearance test is recommended to confirm the air quality is safe. If you choose not to remediate before selling, you must disclose the mold and expect that many buyers will walk away or ask for a significant price reduction.
