We need to address some moisture issues in our crawl space. Water isn't draining properly, and the pea gravel is pretty wet. Water is draining from the house ok, but the problem is ground water evaporating up, and sitting in the crawl (molding a little on the insulation that needs to get torn out!) and overall it's not good.
We had one company come out and try to sell us on the "encapsulation" method, where they put vapor barrier plastic along the bottom and sides of the crawl, close off the exterior vents, and put a vent on the furnace to pipe in conditioned air.
They'd also dig a trench along the bottom of the crawl space with piping to let the water reach the sump pump better.
All that for like $5,500. wheee.
The next company to come out says encapsulation is a bad idea, that it keeps moisture against the foundation without a way for it to really get out. They propose a similar trench/drain/pipe kind of thing along the crawl space perimiter, lining the floor with a vapor barrier, and installing a machine that will keep air moving and pump air out of the crawl. Still waiting on the final bid, but I'm sure it'll be up there, too.
Was curious -- if you have a crawl space, what is going on down there? Have you done any moisture-proofing remedies? What should I consider here?
