I was frustrated because every time it rained, my whole house smelled wet and musty. I realized that my dirt crawlspace was wet and after Damon came out, I ound out I had mold down there. Chris and his crew came out and installed a new vapor barrier and a sump pump system--a dehumidifier unit, too. I wasn't too sure about how it was going to go, but I came home this week and noticed that my house was fresher. My nose doesn't burn. My crawlspace doesn't stink up the house anymore!
