About Certified Waterproofing Inc.

Certified Waterproofing Inc. traces its history in St. Louis to 1888, when it began as a tuckpointing business. Today it focuses on basement waterproofing, foundation work and tuckpointing, and it knows the older and historic homes of the city well. Basement work includes drain tile systems with hydrostatic pressure relief and sump pump installation. Foundation repair covers cracks and interior and exterior sealing, and exterior drainage covers French drains, buried downspouts, drywells and window well drainage. Brick laying is also on the list. A free consultation is offered by phone. Drain tile and pump installations come with a lifetime guarantee against seepage onto the basement floor, and the warranty transfers to a new owner.
