Get belongings away from the wall under the window.

How window well flooding cleanup is handled in O'Fallon, MO
Scan the wall
Thermal imaging shows how far water ran inside the finished wall.

Water is pulled from carpet, pad and the slab.
Open the cavity
Drywall below the window is opened and wet insulation removed.
Dry and verify
Air movers and dehumidifiers run until the wall reaches the drying goal.
Newer O'Fallon basements often have large egress windows set in metal window wells, especially in finished lower levels in WingHaven and the Highway K subdivisions. In a heavy summer thunderstorm, a well with a clogged drain or a downspout emptying next to it fills like a bucket, and the water finds its way through the window seal.
How window well water gets in
- The gravel drain at the bottom of the well is clogged with leaves or silt
- A downspout empties right beside the well
- The grading slopes toward the house instead of away from it
- The window frame or its seal has aged and no longer holds back standing water
Drying the wall under the window
The visible water on the floor is only part of the loss. Water runs down the inside face of the foundation wall and into the framing and insulation of a finished wall before it spreads across the carpet. The tech who does the walkthrough scans that wall with thermal imaging and a pinless meter. Where the insulation is wet, the mitigation team opens the drywall below the window so the cavity can dry, then sets air movers and an LGR dehumidifier.
Trade fact: fiberglass insulation that has been soaked does not dry back to its original performance, so wet batts are usually replaced rather than dried.
Stopping the next one
After the dry-out, the fix is usually outside: clear the well drain, add a clear well cover, extend the downspout and regrade the soil so it falls away from the foundation. The University of Missouri Extension publishes practical home maintenance material, and the National Weather Service St. Louis office posts severe storm warnings for the area. If water also came up through the floor, see basement flooding cleanup.
Window Well Flooding Cleanup questions in O'Fallon, MO
Why did water come through my basement window?
The window well filled faster than its drain could empty, usually because the drain was clogged or a downspout emptied next to it. Once water stands above the sill, it pushes through the seal.
Is window well flooding covered by insurance?
Surface water is treated differently from a sudden pipe leak in many policies. Coverage depends on your policy, so it is worth checking with your own insurer.
Does the drywall have to come out?
Only where it and the insulation behind it are wet. Thermal imaging and meters show exactly where that is.
Will a window well cover stop this?
A clear, sloped cover keeps most rain and leaves out of the well, which prevents most repeat floods.
How long does the dry-out take?
Three to five days is typical once the wall cavity is opened and the equipment is running.
Can I just caulk the window?
Sealing helps, but the real fix is keeping water from standing in the well: a clear drain, a cover and better drainage.
