Basement Waterproofing

Water in a basement is not normal, and paint-on sealers do not fix it. We find where the water is getting in, then build a system that collects it and sends it out of the house.

Signs you need it

What to look for

  • Water or damp patches where the wall meets the floor
  • White, chalky residue (efflorescence) on concrete or block
  • A musty smell that comes back after every rain
  • Stained or peeling paint, warped paneling or rusted appliance feet
  • Puddles that show up after heavy rain or snowmelt

Seeing one of these in Fenton or anywhere in South St. Louis County or Jefferson County? Send us a few details and we will come take a look. Estimates are free.

How we fix it

Our approach

  1. Find the source

    We look at the walls, floor joint, window wells, grading and gutters to see how water is reaching the foundation, and show you what we find.

  2. Collect it at the wall

    An interior drain channel at the footing, with a drainage membrane on the wall where it is needed, captures water before it spreads across the slab.

  3. Move it out

    The system drains to a sump basin and discharges away from the house, so the water leaves instead of cycling back to the foundation.

  4. Close up clean

    We re-pour the concrete over the channel, clean the work area and walk you through how the system works.

Common questions

Basement Waterproofing FAQ

Do I need a full system or just a repair?

It depends on where the water comes from. A single leaking crack can often be sealed on its own. Water coming up at the floor joint along a whole wall usually needs drainage. We tell you which one you have at the estimate.

Will you have to dig up my yard?

Most interior systems are installed from inside the basement, so landscaping and decks stay put. If the fix is outside — grading, downspouts or a French drain — we will say so.

How long does it take?

Most jobs take a few days once scheduled. We give you the expected duration with your written quote, before any work starts.
