Egress Window Leaking Water in Denver? Causes and How to Fix It

Why Your Egress Window Is Leaking Water in Denver

An egress window leaking water is one of the most common problems homeowners face in the Denver metro area—and for good reason. Our Front Range climate brings intense spring snowmelt, sudden hail storms, and heavy afternoon thunderstorms that put serious pressure on basement windows and their drainage systems. If water is seeping into your basement through an egress window, you're not alone, and the good news is that most leaks are preventable and fixable.

At Affordable Egress Co., we've been installing and repairing egress windows throughout Denver and the Front Range since 1999, and we've seen nearly every leak scenario. The problem usually isn't the window itself—it's what's happening around it. Understanding the root cause is the first step toward a dry basement.

Common Causes of Egress Window Leaks in Denver

Poor Window Well Drainage

This is the #1 culprit we see. Your egress window well (the recessed area around the window) needs proper drainage to direct water away from the foundation. Denver's clay and silt-heavy soils don't drain quickly, and if your window well lacks a drain or the drain is clogged, water pools around the window frame during our frequent spring runoff or summer storms. Over time, that standing water finds its way through seals and into your basement.

Improper Window Well Installation

If your window well isn't sloped correctly or isn't deep enough for proper water management, leaks will follow. Colorado building codes require egress windows to meet specific depth and drainage standards, and many older installations or DIY attempts miss these requirements. The well should slope away from the foundation and sit on a proper gravel base.

Deteriorating Window Seals and Caulking

Denver's intense UV exposure and freeze-thaw cycles are tough on caulk and sealant. The sealant around your egress window frame can crack and fail after 5–10 years, especially if it wasn't a high-quality installation. Once that seal breaks, water has a direct path inside.

Gutter and Downspout Issues

If gutters overflow or downspouts empty too close to your foundation, water is directed straight toward your egress window well. We often find that homeowners don't realize their roof drainage is the root cause of basement leaks.

Foundation Cracks and Settlement

Colorado's expansive soils can cause foundation movement, which creates small cracks around window frames. These hairline fractures become water highways during heavy rain or snowmelt.

How to Fix an Egress Window Leak

Step 1: Inspect and Clean the Window Well

Start by removing any debris, leaves, and sediment from your window well. A clogged drain won't function, so flush the drain area with a hose to see if water flows freely. If it doesn't, you may have a blockage that needs clearing.

Step 2: Check the Slope and Grading

Water should flow away from your foundation, not toward it. Walk around your basement exterior and look at the grade of the soil. If it slopes toward the house, that's a problem. The ground should slope away at least 6 inches over 10 feet. Adding topsoil or adjusting the grade can redirect water and may solve your leak on its own.

Step 3: Verify Window Well Drainage

A proper window well includes a drain at the bottom that connects to your foundation drain tile system. If your well doesn't have one, that's likely your issue. Affordable Egress Co. specializes in window well installation and replacement, and we can add or repair drainage systems to code. Most installations are completed in a single day, so you're not waiting weeks for a solution.

Step 4: Reseal and Caulk

If the window itself is leaking around the frame, high-quality exterior caulk can seal small gaps. Use a flexible, waterproof caulk rated for Colorado's temperature swings.

Step 5: Professional Assessment

If you've tried these steps and water is still getting in, it's time to call a professional. Sometimes the issue is deeper—foundation cracks, poor installation, or inadequate original design. A trained eye can spot problems that aren't obvious, and we offer free estimates so you know exactly what needs to be done before any work begins.
