My husband and I were shocked to get a reading of mold during a home inspection. There was no visual mold or water in our home, but we wanted our home to be mold-free.

The process was fast, cost-effective, and worked better than anything we had tried before. Unlike other methods that just clean the surface, this keeps [mold] from coming back.

The first of its kind here in town. So great to have a safe mold remediation option in STL. There is nothing better you can do for the health of your family than making sure your house is mold-free! They offer mold inspections and make it easy.
