If you live in Katy, Texas, you’re in for a treat when fall rolls around. Festivals, 5ks and 10ks, bike rides, and just about anything else you can dream up: it’s all here in Katy. All you need to do is look out the window to see why people here love it so much.
But that’s not all, y’all. With every good thing comes challenges, as every homeowner knows: things like heat, sun, and hurricanes. You’ve seen the watches and warnings; it’s a way of life around here. For residents of Katy, it’s not your first rodeo – or your first storm.

Mold, mildew, condensation, and more are all enemies of a healthy house, and if you own a home in the Katy area, you can’t afford not to protect it.
