Cost

$10–$50


5 Steps for DIY Mold Cleanup

1. Gear Up for Safety

  • Wear:
  • An N95 mask
  • Gloves
  • Goggles to prevent exposure to spores.

2. Prepare a Cleaning Solution

  • Walls: Mix 1 cup of borax with 1 gallon of hot water.
  • Wood: Use soap and water or vinegar for tougher spots.
  • Tile/Hard Surfaces: Combine warm water with detergent.

3. Scrub the Mold Away

  • Method:
  • Use a wire brush for hard surfaces.
  • Use a soft rag for porous materials like wood or drywall.
  • Caution: If mold has penetrated deeply, you may need to remove and replace the material.

4. Dry the Area Completely

  • Steps:
  • Wipe with a clean rag.
  • Run a fan or dehumidifier for 24–48 hours to ensure the area is fully dry.
  • Tip: Borax prevents regrowth, so no rinsing is needed.

5. Contain Mold Spores

  • Dispose:
  • Immediately discard rags and cleaning materials.
  • Wash clothes used during cleaning in hot water.

Mistakes to Avoid

1. Using Bleach

  • Myth: Bleach kills mold.
  • Truth: Bleach changes mold color, making it appear gone but doesn’t remove spores.

2. Skipping the Root Cause

  • Mold will return if humidity or moisture issues aren’t addressed.

3. Painting Over Mold

  • Mold can grow under paint. Always clean thoroughly and dry completely before painting.

When to Call a Professional

  • Area > 10 sq. ft. or significant growth.
  • Cost:
  • Mold remediation: $2,200 on average ($10–$25/sq. ft.).
  • Mold inspection: Prices vary, but hire separate testing/removal companies to avoid conflicts of interest.

Mold Prevention Tips

  • Ventilation: Install and use exhaust fans.
  • Dehumidifiers: Keep humidity levels at 30%–50%.
  • Repair Leaks: Fix pipes, roofs, and windows.
  • Post-Flood Cleaning: Thoroughly clean and dry flooded areas.
  • Avoid Carpet: Replace carpets in moisture-prone spaces.

By following these steps, you can remove minor mold safely and prevent it from returning. For larger or recurring issues, consider hiring a pro to ensure a long-lasting fix.
