Mold in Crawlspace

greenspun.com : LUSENET : Countryside : One Thread

Are whole family has been having allergy symptoms and my 7 month old just got her first ear infection. My husband thinks it might be from mold under the house in the crawl space (dirt is very moist) live in a muccy area. Any ideas on how to get rid of it and kill it safely? Any suggestions are welcomed.

It sound like your crawlspace is not adequately ventilated for your soil conditions. It probably always has a strong wet basement smell. Increasing ventilation may help. Also talk to a contractor about installing a plastic vapor barrier on the bottom of the floor joists.

Several options, cheap to somewhat expensive

Cheap, buy those big sheets (20' x 20') of 4mm plastic at walmart, enough to cover crawl space ceiling, and staple em up. (Be sure to spray lysol or other spray mold/mildew killer on real good first). Cover the staples with the silicone seal available at the car dept. of walmart. (plastic-$4.50, silicone,$3.00/tube, lysol $2.50) Remember, if you don't use enough staples, the thing will sag, and tear. staple every 2 feet.

low-moderate- Spray mold inhibiters (available at large home centers, and pro cleaning shops) which should be applied to ground, walls, and ceiling of crawl space every three monthes. I think Walmart may even have this now.

moderate buy a $150 dehumidifyer, and empty daily. Or, buy more expensive humidyfyer that has a 10' drain hose, and pump pressure when amount of water reaches one gallon. This can be snaked outdoors. Place in crawl space. I suggust you hang weighted plastic or canvess over the crawl space opening to the house, so the allergins can't reach you.

Most expensive, professional waterproofing. The cheapest needs redone ever 3-5 years if put up well. The humidifyers will do a great job of drying, but need checking and routine care. Replace every 5 years or so. The

Remember mold slows up at cool temperatures, and will not be sending spores when it is dry. Maybe place a small exhaust fan into a crawl space window, to encourage air movement. (Be sure there is another window, or entrance open)

I'm also told sometimes the plastic is put on the ground to seal off moisture from it.
