As thousands of homes are in the rebuilding stage after Tropical Storm Harvey, concern over mold in homes is growing.

One group is erasing that concern by providing free chemicals to help destroy mold in homes.

John Wilson picked up five gallons of the chemical today at First Baptist Church in Bevil Oaks.

"Cleanliness and sanitation is a big issue when your home floods, and this stuff is really going to help. It makes you feel like it's going to be safe to be back in your home," Wilson said.

Jeepers 4 Jesus member Scot Shaffer says he’s humbled that he’s helped nearly 7,000 homeowners in Southeast Texas.

"It's definitely critical, I'm no expert by any means, and I tell every person that comes through here I'm not the expert, I'm just the tool handing something out, that's basically it," Shaffer said.

The chemical, called Virex II, works as a bactericidal, virucidal, mildewcidal, and a deodorizer, according to the E.P.A.

The group raised funds to buy up to 30,000 gallons of the chemical, according to Shaffer.

For weeks, Shaffer and others have been handing out a key ingredient to help in the rebuilding process after Tropical Storm Harvey.

“Let us pray with you. That's what we're more interested in, hearing your story, praying with you. These chemicals do one thing but prayer can do a whole lot more," Shaffer said.

Wilson says he’s grateful for the help.

"We're fortunate we've had so much help because that's what it takes. Something like this, you almost can't do it by yourself without help,” Wilson said.

Shaffer says the group may give away more Virex II to other communities in need.
