Raymore barely existed forty years ago. Almost everything here is 90s or newer, built fast on graded Cass County clay, and that combination is why we're out here so often.

Wet basements in Raymore are almost always a soil and drainage problem. The clay around Cass County doesn't drain. It holds water and pushes it against your foundation walls for months after every storm. We stop it at the source.

Frequently Asked Questions — Basement Waterproofing in Raymore
Why do Raymore basements leak?
The graded Cass County clay holds water against the foundation and pushes it at the walls after every storm. On these mostly 90s-and-newer homes, settling on fill can open cracks and gaps where water gets in, and grading around the newer subdivisions often slopes runoff toward the house.
What's the best waterproofing for a Raymore home?
For most homes it's an interior perimeter drain tied to a sump pump that collects water at the floor-wall joint and pumps it out. Individual cracks get injection. We sort out the right setup during the free inspection rather than selling one fix for every basement.
Should I add a battery backup to my sump pump?
We recommend it. The spring storms that flood basements here knock out the power at the same time, and a pump with no electricity does nothing. A battery backup keeps it running through the outage, which is exactly when you need it.
How much does basement waterproofing cost in Raymore?
A single crack injection is relatively low cost, while a full interior drain and sump system runs higher depending on the basement. The inspection and written estimate are free, and we offer financing if you'd rather spread it out.
