We bought a house this past spring. We're in VA on a wooded lot that gets little breeze. Upon the inspection, mold and some wood deterioration was detected in the crawl. We had a engineer/handyman look at the floor structure and he gave it the green light.
The homeowners had put down a vapor barrier a year or two ago and it had a few gaps in it near the footers (I've been reading it needs to be sealed tight).
The homeowners had a pest company come in and treat the wood for mold and install 70/30 auto vents.
Ever since then, we have been dealing with moisture problems down there. It has been a rainy year but I am very concerned about structural damage to the house and recurring maintenance issues.
I've hired the company to come back in and treat the mold again (it cropped back up). Also, our insulation was ruined by moisture seeping into it. We have to replace that.
He installed a fanned vent to draw air through the crawl which is controlled by a thermostat set at 50 - 55 degrees.
Our biggest problem was condensation on the ductwork and water pipes during the hot, humid summer.
We're hoping that will work.
We had problems with water seeping in from a downspout close to the house but with extended that downgrade into the yard and didn't have any problems since.
Tonight, I had a shocking experience.
We got 4" of rain from Ivan last weekend and got 5" of rain from Hurricane Jeanne today.
I wanted to see if it did anything to the crawl and went down there and to my surprise
there was about 2" of standing water everywhere.
The pest guy had pulled up the vapor barrier to do the mold treatment so it was just the dirt floor in water.
I did a perimeter check and all downspouts appeared to be carrying water away from the foundation.
I'm concerned about the water spreading mold, etc. I'm also concerned because our 1st floor HVAC unit is down there and don't want it to get damaged.
I'm really at a loss at what to do.
Any help would be much appreciated.
