Basement waterproofing
Window Well Drainage in the North Metro
Window wells are a common, overlooked way water gets into a basement. A local contractor clears, repairs, or rebuilds well drainage so rain and snowmelt don't overflow straight through your basement windows.
What window well drainage is and when you need it
Window wells are one of the most common — and most overlooked — ways water gets into a north metro basement. A window well is basically a hole in the ground next to your foundation, lined with a metal or plastic surround, that lets light into a below-grade basement window. When it works, it's fine. When the drainage fails, it turns into a bucket that fills with rain, snowmelt, and runoff, and once it overflows, the water has nowhere to go but through the window and into your basement.
The usual cause is a missing, clogged, or failed well drain. Most window wells are supposed to have a drain at the bottom that ties into the footing drain system or daylights somewhere downhill, so water that collects in the well flows away instead of building up. Over the years, those drains silt up, get blocked by leaves and debris, or were never installed correctly in the first place. Add a cover that's cracked, missing, or full of leaf litter, and a single spring storm can dump enough water into the well to overwhelm the window seal and flood the basement.
The fix depends on what's actually wrong. If the well has a working drain that's just clogged, a contractor can clear it and clean out the gravel. If the drain is missing or failed, the contractor may dig down, install a new drain tied to the footing system or a dry well, and refresh the drainage stone. If the well itself is too small, has settled, or is letting soil wash in, it may need to be rebuilt or replaced with a properly sized well and a good cover. Covers matter more than people think — a solid, well-fitted cover keeps out leaves, snow, and debris, which is what clogs the drain in the first place, and it keeps the well from filling during a storm.
Window well problems tend to show up in homes built from the 1960s through the 1980s, where the original wells and drains have had decades to fill with sediment — which is a lot of the north metro housing stock. They're also common on homes where the grading has settled over time and now slopes toward the well instead of away. If you've had water come in through or under a basement window, or you can see standing water in a well after a rain, that's the sign. It's a relatively simple fix compared to most basement waterproofing work, and catching it early keeps a small overflow from soaking the carpet, drywall, and framing around the window.
After your free inspection, a contractor will check each well, the drain, the cover, and the grading around it, and tell you plainly what needs doing — whether it's as simple as clearing a clogged drain and adding a cover, or whether the well itself needs to be rebuilt. Either way, it's one of the more affordable basement fixes, and it stops a surprisingly common source of water damage before it happens again.
What this includes
- Clears clogged or missing well drains
- Keeps snowmelt and rain out of the well
- Reduces debris and pest entry
FAQ
Window Well Drainage questions, answered
Why does water come in through my basement window?
Usually because the window well's drain is clogged, missing, or failed, so rain and snowmelt collect in the well and overflow through the window. A contractor clears the drain or installs one, adds a good cover, and checks the grading so water runs away from the well instead of into it.
Do I need a window well cover?
A well-fitted cover is worth it. It keeps leaves, snow, and debris out of the well, which is what clogs the drain in the first place, and it stops most rain and snowmelt from filling the well directly. A cover won't fix a failed drain, but it's an inexpensive part of keeping the system working.
Can a window well drain be installed if my house doesn't have one?
Yes. A contractor can dig down in the well, install a drain tied to your footing system or a dry well, and refresh the drainage stone. It's a routine fix for older north metro homes where the original drain was never installed or has long since silted up.
How much does window well drainage repair cost?
It varies with the scope — clearing a clogged drain is inexpensive, while installing a new drain or rebuilding the well costs more. A local contractor gives you a clear, itemized quote after your free inspection so you know exactly what's involved.
