Mission built out right after the war, which makes its housing stock some of the oldest in Johnson County. Foundations here have been working against the clay since the 40s.

Frequently Asked Questions — Basement Waterproofing in Mission
Why do Mission basements leak?
These post-war foundations have spent 70 or 80 years against Johnson County clay that holds water and pushes it at the walls after every storm. Over that many decades the original concrete and block develop cracks and joints that let water seep through, especially in heavy spring rains.
What's the best waterproofing for an older Mission basement?
An interior perimeter drain tied to a sump pump handles most of these compact homes, collecting water at the floor-wall joint and pumping it out. Individual cracks get epoxy or polyurethane injection. We figure out the right mix during the free inspection.
Can you waterproof a small finished Mission basement?
In most cases, yes. We can open a narrow strip of finished wall at the base to run the drain and patch it back, or route the system through unfinished utility areas. In a smaller home we work hard to keep the disruption minimal, and we show you the plan first.
How much does basement waterproofing cost in Mission?
A single crack injection is on the lower end, while a full interior drain and sump system runs higher depending on the basement. The inspection and written estimate are free, and financing is available if you'd like to spread the cost.
