Crawl space dehumidifiers?

In another thread I posted pictures of about 2” of water in my flooded crawl space. I sucked it out with a utility pump and opened all the crawl space vents. We have not had any heavy rains like we did with the spring thaw and the April showers so there is no more collecting water. However the ground is certainly muddy and it smells like musty dirt which comes up into the house.

I thought I needed a sump pump, but if I had bought one there would be nothing for it to pump out for the past few weeks. I have seen sump pumps that don’t work get locked up so they don’t perform if you do need them.

What I think would be good to cut down on the smell is a crawl space dehumidifier or some kind of fan system. I googled crawl space dehumidifier and they sell some for over $1000.00. Please make a more thrifty recommendation. Thank you.

Can you get any good x-ventilation with vents.... then either a temp plug-in fan, if it's an intermittant problem, or a humidity controlled power vent.... maybe $200 to $300.

In Socal, we got caught without roof during the Nov Dec rains of several years ago. To keep from destroying out our flooring, we had to cut it open and let it drain into the perimeter crawlspace foundation. It got saturated.

We had to install those big carpet drying fans, and it took months to dry out. So if fans don't accomplish the task immediately.... give them a chance.


Never stop learning (xcep fer speling en typeing)

I googled that, but they look small. Do they go according to squ ft or will it all eventually get done? Can you tell me anything more about them?

Actually, now that I take another look aren't they just bath fans?
