Mold in the crawl space is one of the top three mold problems common to a home, affecting 33% of all crawl spaces in the United States, if left untreated cause a total loss of a home from severe mold infestation.
Mold spores Move quickly threw Cracks and HVAC / A/C Systems.
Mold remediation and decontamination are based on five principles:
Protect the health of occupants and workers
Document conditions and work
Control source of contamination
Remove the contamination
Fix the moisture problem
Mold does not need a lot of water to grow. Common sources of water or moisture include roof leaks, condensation due to high humidity or cold spots in a building, slow leaks in plumbing fixtures, humidification systems, sprinkler systems, and floods.*
Besides moisture, mold needs nutrients, or food, to grow. Mold can grow on virtually any organic substance. Most Crawl spaces are full of organic materials that mold can use as food, including paper, cloth, wood, plant material, and even soil. In most cases, temperature is not an issue; some molds grow in warm areas, while others prefer cool locations such as bread stored in a refrigerator. Often, more than one type of mold can be found growing in the same area, although conditions such as moisture, light, and temperature may favor one species of mold over another. All crawl spaces must be vented properly.
Using air Movers (fans) air out your crawl space to insure the area is dry prior to starting your Remediation. Some crawl spaces will require the use of a dehumidifier to remove excess water from the space. The space should be as dry as possible (below 30% relative humidity)
Some Professional request a HEPA filter system and/or Negative air machines during this process to prevent mold spores from moving.
Some crawl spaces may need to have new plastic placed down over the dirt after the remediation process is completed and some will need concreted in to prevent water from entering the crawl space.
Throw Away Damaged Materials
Mold-contaminated building materials that cannot be salvaged should be double-bagged in 6-mil or thicker polyethylene bags.
STEP ONE:
A contaminated area can be contained with a single layer of
polyethylene sheeting and duct tape.
A slit should be made for entry.
A respirator, gloves, and goggles
should be used for protection.
Step Two:
Apply Moldstat: Plus with a pump sprayer .apply a level coat of solution, 6 -8 inches away from surface. Rub with a brush, sponge or cloth.or can be use with a Fogging Machines devide the crawl space area into 15’ x 15’ areas. You will move the fogger to each area, fogging generally 45 minutes each Do not breathe spray mist.
This step is recomend if area is able to work in Step Three:
Mold Resistant
Coating and Encapsulator
Pump spray the Encapuslator on all areas around and on the affect area. This Encapsulator is a EPA registered fungicide that is UV resistant and ready to use. This prevents water and mold from penetrating new and old materials. Contains a vanishing tracer dye to indicate coverage.
This product can be spray with a airless paint sprayer or applied with brush and roller.
