Falling Leaves, Rising Risk: Your Essential Fall Window Well Maintenance Checklist

The leaves are turning, the air is crisp, and cozy sweaters are making their annual debut. Fall is a beautiful time of year, but for homeowners with basement window wells, it's also a critical time for maintenance.

Window wells are your basement’s first line of defense against water intrusion. They allow natural light and, crucially, provide emergency egress. However, as the season shifts, your wells can quickly turn from protective barriers into potential problem spots.

Here is your essential guide from Window Well Supply to preparing your wells for the winter ahead.


1. The Debris Trap: Clean Out the Well

The number one fall threat to your window wells? Leaves, pine needles, and sediment.

  • The Problem: Fallen leaves quickly pile up, creating a soggy layer that traps moisture directly against your basement window and, more importantly, clogs your drainage system. If your drain is blocked, heavy fall rain or melting winter snow will turn your well into a bathtub, flooding your basement.

  • The Fix: Grab a small rake, trowel, or even a shop vac and meticulously remove all accumulated debris. Ensure the bottom gravel is loose and that the drain is completely clear.

2. The Structural Check: Inspect for Damage

Autumn is your last chance before the deep freeze to spot small issues that could become major problems over winter.

  • Check the Walls: Inspect the window well walls (metal, plastic, or concrete) for any signs of rust, bowing, cracks, or gaps where the well meets your home's foundation. Rust or small cracks can quickly worsen when water freezes and expands.

  • Check the Window Seals: Look closely at the caulking and weatherstripping around your basement window frame. Cold weather and moisture will exploit any tiny crack, leading to drafts and leaks. Apply fresh exterior-grade caulk to seal any compromised areas.

  • Check the Gravel: Make sure you have at least 4-6 inches of clean, loose gravel at the bottom to facilitate proper drainage to the foundation's weeping tile system.

3. The Ultimate Defense: Install or Secure Your Window Well Cover

The single most effective thing you can do to winterize your window well is to cover it—and fall is the time to do it.

  • Prevent Debris and Snow: A well-fitted cover acts as a shield, keeping out 99% of leaves, dirt, and eventually, heavy snow. This keeps your drain clear and prevents massive snow accumulation inside the well.

  • Stop Water Buildup: High-quality polycarbonate covers are designed to shed water away from the well and foundation, providing an extra layer of protection during heavy rain or melting periods.

  • Improve Safety: An uncovered well is a hidden hazard for pets, children, and delivery drivers. A sturdy, secured cover offers peace of mind.

4. The Final Grade: Look at Your Landscaping

Your window wells are part of your home's larger water management system. Before the ground freezes:

  • Clear Downspouts: Ensure all gutters and downspouts are clear of leaves and direct water at least six feet away from your foundation and window wells.

  • Check Grading: Confirm that the soil and landscaping around your home are sloped away from the foundation, not toward it. Water running towards the house will inevitably funnel into the window wells.


Taking an hour this fall to inspect and prepare your window wells is a small investment that offers a massive return: a dry, safe, and worry-free basement all winter long.
