"Stephen and Wendel's crew at Key Waterproofing Construction did an excellent job in waterproofing my basement with cement. They were extremely professional, and superfast. Completed the job in five hours, had a crew of six, to completed a foundation of 200 sq ft. The price was right and job was impeccable, crew left the site nice and clean."
