We Stop Water Before It Hits the Basement Floor
When water collects in window wells, it doesn’t take long for moisture and water to penetrate into your basement. A proper window well drainage system keeps that from happening by guiding rainwater down and away from your foundation, even during heavy storms.
At Diamond Masonry & Waterproofing, we’ve seen what happens when wells are ignored, and we know how to fix it the right way.
Here’s how we approach it:

Yes, without proper window well drainage, water can collect and seep into your basement. A working drain helps move water away before it becomes a bigger issue.
It’s usually due to poor drainage, clogged or missing drains, or improper grading around your home. We inspect and fix all of those to keep water out for good.
The drain is typically located at the bottom of the window well, connecting to a perimeter drain or sump pump system. If water isn’t draining, that connection might be blocked, or missing entirely.
No worries, we can properly install a window well drainage system that fits your home. It’s a simple upgrade that prevents water buildup and basement leaks.
We usually use clean gravel at the base to improve drainage and help filter debris. It supports water flow toward the drain while keeping things neat and functional.
Water often leaks in when the window well lacks proper drainage or grading. Solutions include installing a window well drain, adding gravel for filtration, and ensuring the surrounding soil slopes away from the home. Sealing gaps around the window can also help, but drainage is usually the core issue.
A well-functioning window well typically includes a vertical drain pipe filled with gravel, which connects to either a French drain system or your home’s perimeter drainage. This setup allows water to filter down and away efficiently, preventing overflow during storms.
You should have at least 6 inches of clean, coarse gravel at the bottom of the window well. The gravel helps with water filtration and prevents soil from clogging the drain pipe. Too little gravel can lead to standing water and drainage issues over time.
If water disappears quickly after rain and there’s no pooling, overflow, or leakage into the basement, your drainage system is likely doing its job. If you notice dampness, water stains, or water sitting in the well, it’s time for an inspection from one of our professionals.
Installing a window well drain involves digging a vertical pit at the bottom of the well, filling it with gravel, and connecting it to a drain pipe that ties into a sump pump or a broader drainage system. Proper depth and alignment are key to ensuring long-term effectiveness.
