What we do
Every way water gets in, covered.
Water in a basement isn’t normal, and ignoring it gets expensive. These are the five jobs we do.
Basement Waterproofing
Interior drainage systems that catch water where it enters and move it out before it reaches your floor.
How we fix it
Foundation Crack Repair
Leaking or widening cracks in poured concrete walls sealed and reinforced so they stay dry and stay put.
How we fix it
Sump Pump Systems
New sump pump installs and replacements, sized for your basement and discharged properly away from the house.
How we fix it
French Drains & Yard Drainage
French drains and buried drain lines that move standing water away from your foundation and out of your yard.
How we fix it
Downspout Extensions
Buried downspout lines that carry roof water well away from the house instead of dumping it at your foundation.

Why M.O.M.

St. Louis clay holds water against foundations, and our freeze-thaw winters open up cracks. This is the housing stock we work on, so we know what actually stops the water here.
- Source first. We trace the water before we recommend anything.
- Straight answers. If a downspout extension will solve it, that’s what we’ll quote.
- Fully insured. Your home is covered while we work on it.
- You deal with the people doing the work. Locally owned, based in Fenton.

Common questions
Before you call
Short answers to what homeowners ask us most.
Is a little water in the basement normal?
No. Even a small recurring damp spot means water is finding a path through or under the foundation. It rarely gets better on its own, and it is cheaper to deal with early.
Do you charge for estimates?
No. Estimates are free. We look at the problem, explain what we see and give you a written quote.
Are you insured?
Yes. Masters of Moisture is fully insured.
