What to Do If Mold Is Found During an Inspection

Mold observed during a property inspection can feel alarming and create tension for parties on both sides of the transaction. The good news is that most mold issues are common, manageable, and fixable with the right steps. A property inspection doesn’t just reveal problems, it gives you the information you need to make smart decisions throughout the entire purchasing process.Mold

If mold is observed or suspected during your inspection, here’s how to move forward with confidence.

1. Understand Exactly What was Observed

The Inspection Report will outline:

  • The location of the mold-like* substance
  • Any observed conditions contributing to moisture (Observed leaks, poor ventilation, high humidity, etc.)
  • Whether the area is localized or widespread
  • Recommendations for further evaluation

*-Inspectors do not diagnose the type of mold, however do identify the presence of visible microbial growth and the conditions that allow it to thrive. The only way to confirm mold and the type of mold is to have laboratory testing, which in most cases not necessary.

2. Don’t Panic—Mold can be Remediated

Mold is a moisture problem first and a cleanup problem second. In most cases, the presence of mold doesn’t mean the property is unsafe or unlivable. It simply means the issue needs to be addressed properly.

  • Summary of Recommendations by Size
    • Typical Mold Size Level Actions Required
      • Small – If the affected areas is less than 10 sq ft, most property owners can perform the cleanup. Proper protective gear must be worn: N95 mask/gloves/goggles.
      • Medium – If the affected area is 10-30 sq ft, a professional will likely be necessary as this may involve specialized HEPA equipment and limited containment.
      • Large – If the affected area is 30-100 sq ft A professional is necessary and may involve full containment.
      • Extensive –  If the affected area is greater than 100 sq ft or involves the HVAC system, remediation requires significant expertise, specialized expertise and equipment as well as complete containment.

3. Bring In a Qualified Mold or Environmental Professional

Your next step is to consult a:

  • Certified mold remediation contractor, or
  • Environmental hygienist for testing and scope of work

These specialists will:

  • Confirm the type and extent of mold
  • Identify the moisture source
  • Provide a remediation plan and cost estimate

This information helps you understand the true scope of the issue.

4. Identify and Correct the Moisture Source

Mold will return if moisture remains. Common causes include:

  • Plumbing leaks
  • Roof leaks
  • Foundation seepage
  • Poor ventilation
  • High indoor humidity

Fixing the moisture source is non-negotiable and should happen before or alongside remediation.

5. Get a Remediation Plan and Estimate

A professional remediation plan may include:

  • Containment of the affected area
  • Removal of contaminated materials
  • Cleaning and sanitizing surfaces
  • Air filtration
  • Post-remediation verification

Having a written plan helps you negotiate repairs or credits with the seller.

6. Use the Findings in Your Negotiations

Buyers typically have several options:

  • Request the seller to remediate the mold before closing
  • Ask for repair credits or a price reduction
  • Proceed with the purchase and handle remediation yourself
  • Walk away if the issue is severe and the contract allows it

Your Real Estate Broker can help you decide which path makes the most sense.

7. Get Post‑Remediation Documentation

Once the work is complete, ask for:

  • A clearance report or post‑remediation verification
  • Receipts and warranties from the contractor
  • Confirmation that the moisture source was corrected

This documentation protects you and provides peace of mind.

8. Keep Mold Prevention in Mind Going Forward

Even after remediation, good property maintenance helps prevent future issues:

  • Maintain proper ventilation
  • Use exhaust fans in kitchens, maintenance areas and bathrooms
  • Keep humidity below 50%
  • Address leaks immediately
  • Ensure gutters and grading direct water away from the property

A dry building is a healthy building.
