Window Well Extensions & Replacements

Water in your window well? Rusted-out steel that's caving toward the glass? These are the two most common window well problems in Chicagoland β€” and both have permanent fixes. Well Covered raises, extends, and replaces window wells on site across the Chicago suburbs.

Why Window Wells Fill with Water

Most leaking wells sit at or below the surrounding grade. Every rain sends yard runoff straight over the lip and into the well, carrying soil that settles inside and plugs the drain. Once the drain is buried, the well holds water against your basement window like a fish tank β€” and window frames aren't built to hold back standing water. Landscaping projects and settling soil make this worse over the years: the yard slowly rises while the well stays put.

The Fix: Raise the Well Above Grade

A window well extension raises the top of your existing well so it sits above the surrounding ground β€” the rule of thumb is several inches above grade β€” so surface water flows around the well instead of into it. Combined with a fitted cover, an extended well stays dry through spring thaws and summer downpours.

  • Raises the well rim above the surrounding grade
  • Stops soil erosion from washing over the lip and plugging the drain
  • Rugged galvanized steel that matches your existing well
  • Typically done in the same visit as a new cover

When Replacement Beats Repair

Steel wells eventually rust through β€” first at the soil line, then everywhere. A rusted well loses its strength, lets soil push through, and can start collapsing toward the window. If your well is rusted out, deformed, or pulling away from the foundation, we replace it outright with new galvanized steel, fitted and anchored to your foundation. We handle steel, concrete, and block well situations.

Warning Signs to Watch For

  • Standing water in the well after rain
  • Soil washing into the well or a buried drain
  • Rust holes or flaking steel at the soil line
  • The well pulling away from the foundation or leaning toward the window
  • Musty smells or damp drywall in the basement near the window

Frequently Asked Questions

How high should a window well be above the ground?

The well rim should sit above the surrounding grade β€” several inches β€” so runoff flows past it. If your yard has risen over the years from landscaping and settling, an extension restores that height.

Do I need an extension or a full replacement?

If the steel is sound and the well just sits too low, an extension solves it. If the steel is rusted through or deforming, replacement is the right call. We'll tell you honestly which one you need at the free estimate.

Will this stop my basement window from leaking?

In most cases water at a basement window starts as water standing in the well. Raising the well and covering it removes the standing water at the source. If water is coming through the foundation itself, we'll tell you that too.

How long does the work take?

Most extensions and replacements are completed in a single visit, often together with a new custom cover.
