Mold Mitigation & Remediation

---

To prevent secondary damage after water damage, it’s essential to act quickly and thoroughly to address the water, dry the area, and control humidity. Here’s a step-by-step approach:

• Inspection: Conduct a thorough inspection of the affected areas, including behind walls, under flooring, and in areas like basements and crawl spaces. Use moisture meters to check dampness levels, as moisture can linger even after standing water is removed.

• Documentation: Take photos and videos of damage for insurance purposes, as many policies cover mold remediation after a flood.

• Water Extraction: Use pumps to remove standing water, followed by wet vacuums for any residual water.

• Dehumidifiers & Fans: Run industrial-strength dehumidifiers and fans to thoroughly dry out the area. Increasing ventilation is key to preventing further mold growth. If possible, keep windows open to aid in the drying process.

• Remove Wet Materials: Dispose of water-damaged items like carpets, drywall, insulation, and furniture. Mold grows easily on porous materials, so anything that can’t be dried or cleaned thoroughly should be removed.

• Isolation: Use plastic sheeting and seal doorways to prevent mold spores from spreading to unaffected areas.

• Negative Air Pressure: If possible, create negative air pressure using an air scrubber to contain and filter mold spores in the affected area.

• Scrub with Mold Cleaners: Hard surfaces like wood, metal, and glass can be scrubbed with a mold-killing solution, like a mixture of bleach and water (1 cup of bleach to 1 gallon of water), or commercial mold cleaners. Avoid mixing bleach with ammonia or other cleaners, as this can release toxic fumes.

• Disinfect Non-Porous Surfaces: Use antimicrobial solutions on cleaned surfaces to kill lingering spores and prevent mold regrowth.

• Dispose of Contaminated Materials: Place all removed materials in heavy-duty trash bags, seal them tightly, and dispose of them properly according to local regulations.

• Antimicrobial Coatings: After cleaning, apply antimicrobial treatments to areas like floors, walls, and wood studs to prevent future mold growth.

• Sealants: In some cases, applying sealants to mold-prone surfaces can help keep spores from re-attaching. This is particularly useful in basements or areas that might be exposed to future moisture.

Test for Air Quality

• Mold Testing: After remediation, consider air quality testing to ensure mold spore levels are safe. This is particularly important for people with respiratory issues or mold allergies.

• Humidity Monitoring: Keep humidity below 50% to prevent future mold growth. Consider installing a permanent dehumidifier in flood-prone areas like basements.

• Waterproofing: Consider waterproofing solutions like sump pumps, waterproof sealants, or backflow valves to prevent future floods.

• Ventilation Upgrades: Ensure adequate ventilation in all areas of the house to control humidity, especially in basements, attics, and bathrooms.

• Regular Inspections: Check areas prone to moisture, like crawl spaces, basements, and attics, especially during rainy seasons.

• When to Call a Pro: If the area is large (over 10 square feet), or if mold is growing behind walls or in HVAC systems, it’s best to hire certified mold remediation professionals. They have specialized equipment and training to safely remove and contain mold.
