Crawl Space Issues
Can someone please give me some advise? We have a crawl space that is very wet and is starting to smell like mildew. The floor is sand, on top of earth. We have 2 air vents in the crawl space and the humidity is up to 86%. I've also started noticing some white mold on some of the floor joists AND there is black mold at the bottom of the only support beam in there.
I've read a few articles about drying out crawl spaces and they give 2 completely different ways of accomplishing this. One way is to add a sump pump, a dehumidifier, a metal jack to replace the support beam that is decaying, completely blocking the 2 vents that are there, then wrap the entire area so the mold won't spread. This way is VERY costly.
Another way was suggested to just add automatic vent fans that would turn on automatically when the humidity got too high, then turn off automatically when it was more under control. They also suggest using a metal jack to take on the support of the decaying beam, and also suggested to wrap the entire area after you add the fans. This way is much more reasonable, but I'm so confused about which way is the right way to take care of this. Any suggestions would be greatly appreciated!
