Mold, How to Prevent & Eliminate
The key to prevent mold is moisture control.
Mold is present in every home or where ever moisture is present. By reducing the moisture in the crawl space, it reduces the chance of mold growing to harmful levels under and in a home.
“The U.S. EPA states: “Molds are usually not a problem unless mold spores land on a wet or damp spot and begin growing. Molds produce allergens, irritants and potentially toxic substances. The key to mold control is moisture control. The mold will not grow if moisture is not present (source: EPA “ A Brief Guide to Mold, Mildew and Your Home,” publication #402-K-02-003).”
The crawl space is the number one source for potential moisture entering your home. The moisture my be equal to gallons of water but in vapor form and not even visible. The Seal Tight System will eliminate the moisture in the crawl space from entering home as well as eliminating musty odors, mold, mildew and radon gases.
How to eliminate and prevent future mold growth.
Spray the effected areas with a mold killing and growth preventing spray. This product is not yet available for sale on our site ,but there are good products for purchase at your local building supply house. Not until STS has tested and proven a product that we feel we can back 100% will we add it to our site. This is not saying that products sold at building supply houses are not good or ineffective, just not tested by STS.
The Myth Of Using Bleach To Kill Mold!
Mold has a root system that actually grows into the surfaces of wood, drywall, concrete, etc…, like tree roots grow into the soil. The roots are not killed by bleach alone because the bleach does not penetrate the surface of porous materials. The bleach chemical portion sits on the surface until gassing off, killing only the mold on the surface leaving the roots intact, while the water portion of the bleach soaks into the material giving the mold roots a food source to start growing again. Think of it this way, if you were to cut a tree, plant, grass, or anything that has roots down and you water the area, you will see what you cut start to grow again. This is because the roots were not killed. The other problem with using bleach for an extended period is that if sprayed on wood and other building materials it actually starts to break down the products.
STOPPING MOLD AT THE ROOTS IS THE ONLY WAY!!!
Chlorine Bleach is NOT a registered EPA Mold Killing product!
If you think that we’re just knocking bleach. Don’t take our word for it! Go to www.epa.gov/mold/moldcourse/index.html and read what the EPA has to say about using bleach to kill mold. The EPA says that “The use of bleach is not recommended as a routine practice during mold clean-up” http://iaq.custhelp.com question #7.
Now you might ask: How do I kill mold if not with bleach?
Answer: Use an EPA approved and registered fungicide to kill the mold at its roots.
Where does mold grow best?
Mold is a fungi. There are more than 100,000 known species of mold. Mold can survive the cold of space and high temperatures. High spore levels in the air can create bad health effects on people. Over exposure can cause breathing problems, congestion, hay fever, and allergies just to name a few. Water damaged building materials is a good food source to promote mold growth in the home environment. The following is a list of places and items that if damp promote mold growth:
- Crawl Spaces
- Concrete, Brick or Stone
- Damp, dark areas
- Wood products
- Ducts for heat & cooling
- Paper & cardboard products
- Under sinks
- Basements with water problems or dirt floors
- Decks & Patios
- Clothing materials
- Carpets, padding & drapes
- Furniture & Upholstery
- Behind and on wallpaper
- Leather products
- Anything or anywhere moisture can be soaked up or stay damp/wet for an extended period
Preventing Mold Growth in a Crawl Space:
The odds are that most crawl spaces have some amount of mold present. The best way to eliminate any mold problem is to first install the STS Pro-Shield Liner System, this seals out the moisture coming up from the soil. After the liner is installed and sealed, the next issue is to seal the sump pump pit with the STS Sump Pit Cover. This is the last place moisture can inter the crawl space coming up from the soil. The last step to prevent mold growth is to spray a EPA approved and registered fungicide around the top of the foundation above the liner and floor joists, making sure any and all signs of past or present mold affected areas are sprayed. Eliminating moisture in the crawl space will help prevent future mold problems and increase the air quality and overall healthiness of the living environment.
