Sump Pumps
Installation, replacement, battery backup
What We Do
Basements in this part of Missouri depend on sump pumps, and pumps fail quietly until the day they don't. We replace worn pumps, install battery backup systems that run when the power goes out in a storm, and correct discharge lines that dump water right back against the foundation.
- Sump pump testing and replacement
- Battery backup and water-powered backup systems
- Check valve, float, and discharge line repair
- Pit and basin work
What to Expect
Request service through Housecall Pro, or call or text to discuss the problem. Estimates are free, with no service-call fee. We review the proposed work and pricing with you, and send an arrival text before the visit.
