"When they get excessively damp, you have mildew and mold and wood decay growing on the wood. Generally it'll be on the wood. Sometimes it'll be on the insulation.

KNOXVILLE (WATE) - After all the rain that's hit East Tennessee already in the month of July, a lot of folks in the area are still trying to dry out.

Homeowners should make sure the crawlspaces underneath their home is free of water dumped by those storms.

If moisture has gotten in there, it can lead to the nagging and somewhat dangerous problem of mold.

But there are ways to keep it out.

After several consecutive days of rainfall the first week of July, 6 News heard from several viewers who said water had gotten into their homes.

Moisture that gets trapped in crawlspaces during this warm time of year can create the perfect breeding ground for mold.

Local mold removal companies like Dayton's Pest Control in Knoxville say they see it all the time.

"When they get excessively damp, you have mildew and mold and wood decay growing on the wood. Generally it'll be on the wood. Sometimes it'll be on the insulation. If there's anything stored under here, it'll grow on that," said Dayton Hylton, owner of Dayton's Pest Control.

Hylton says mold can grow as quickly as overnight, leading to serious issues like a weak foundation or health problems caused by the mold spores that can rise into a home.

"You're trapping it in the house and then breathing it in," said Hylton.

He says it can also be costly to get it removed.

"That would be in the $1000 to $2000 range, but you can go much higher than that," said Hylton.

Dayton's says prevention is the better way to go.

The company installs crawlspace encapsulation systems, which essentially seal the entire area underneath your house off, so that water can't find its way in.

They place a waterproof liner on the ground and seal off the vents leading into the crawlspace.

"We want it to seal and not have any outside air," said Hylton.

The system also includes a dehumidifier to ensure the space beneath your homes stays dry.

"We dry out the crawlspace to the point where the mildew, mold or fungus won't grow," said Hylton.

Dayton's says most people probably don't even know they have water in their crawlspace.

They recommend getting it checked at least twice a year as well as every time there are periods of significant rainfall.
