A Flooded Window Well Is a Drainage Problem
When a window well fills with water during a storm, that water has nowhere to go but through the window and into the basement. Replacing the window doesn’t help if the well keeps filling. The real fix is giving the well a way to drain and keeping water from collecting there in the first place.
Three Reasons a Window Well Fills
No well drain (or a clogged one)
A proper well has a drain tied into the foundation drainage system. Without it — or when it’s silted shut — the well becomes a bucket.
Grading toward the well
If the soil slopes toward the house, surface water runs straight into the well during every heavy rain.
No cover
An uncovered well catches rain and debris directly, filling faster and clogging the drain.
How a Leaking Window Well Should Be Fixed
When it’s the right fix
Establish or clear a well drain that ties into the footing drain or sump, set a proper gravel base, grade the surrounding soil away, and add a cover. Now the well sheds water instead of holding it.
When it’s the wrong fix
Replacing the window or caulking the frame while the well still floods. The next storm fills the well and pushes water right back through — the window was never the problem.
What a Proper Window Well Drainage Fix Includes
We solve why the well floods, then protect the window.
Window Wells & Egress in the Quad Cities
Many Quad Cities basements rely on window wells for egress and light, and the same clay and high water table that drive basement leaks make wells flood. A drained, covered, properly graded well keeps the basement dry and the egress usable — which is how it should have been built.

Frequently Asked Questions
Why does my window well keep filling with water?
Almost always because it has no working drain, the ground slopes toward it, or it has no cover — so it collects water faster than it can escape. We find which and fix the drainage.
Do I need a window well cover?
A cover helps a lot — it keeps rain and debris out and protects the drain. But a cover alone won’t fix a well with no drainage; the two work together.
Does the well drain tie into my sump?
It can tie into the footing drain or sump system, depending on your setup. The goal is to route well water into the same path that carries the rest away from the foundation.
Can you fix it without replacing the window?
Often yes — if the window is sound, fixing the drainage stops the leak. We only replace the window if it’s actually failed.
Is this related to egress windows?
Yes — egress window wells need to stay dry and usable. We install and correct both; a proper egress well is drained and covered by design.
