When winter hits Fort Collins, many homeowners prepare for snow, ice, and freezing temperatures—but one area that often gets overlooked is your window well drainage system. If your window wells aren’t properly maintained, frozen drainage can quickly lead to basement flooding, costly damage, and major headaches.
In this month’s blog, we’ll explain how frozen or clogged window well drainage creates flooding risks, what signs to look out for, and how to prevent it.
How Frozen Drainage Leads to Basement Flooding?
Basement window wells are designed to channel water away from your home—but when they freeze or clog, the system backs up. Here’s how it typically happens:
1. Clogged Drains
Leaves, dirt, and debris build up over time—especially during fall and early winter—blocking your window well’s drain. When snow begins to melt, that water has nowhere to go and starts accumulating.
2. Ice Dams and Frozen Water
If there’s standing water in the window well, it can freeze overnight, forming a solid ice dam that blocks any further water from draining. This frozen blockage acts like a lid, trapping additional water during thaw cycles.
3. Snowmelt Overload
In Fort Collins, snowmelt can happen quickly during warm winter days. If your window well can’t keep up, water will overflow the top edge and seep into your basement windows, potentially damaging drywall, insulation, flooring, and even your home’s foundation.
How to Prevent Window Well Flooding This Winter?
1. Clear Debris Before Winter
The simplest way to prevent clogged drainage is regular window well maintenance. Clear out:
Fallen leaves
Dirt and mud
Twigs and other natural debris
This ensures your drain stays clear when winter storms roll in.
2. Install Durable Window Well Covers
A properly fitted window well cover (especially polycarbonate or custom metal designs) keeps snow, debris, and ice out of the well. This drastically reduces the chance of frozen buildup or blockages.
Covers also enhance safety, energy efficiency, and prevent wildlife or small pets from falling in.
3. Ensure Proper Drainage Flow
If you notice standing water even in dry conditions, your window well’s drainage system may be failing. In this case, you may need window well repair or professional maintenance. Common issues include:
Crushed or clogged drainage pipes
Poor grading around the window well
Inadequate gravel layers at the well base
Gravel should be 6–8 inches deep and sit below the window sill for best performance.
4. Monitor Snow Accumulation
Even with a well cover, heavy snow can weigh down the system and block light. Shovel or brush off accumulated snow after storms to relieve pressure on the cover and allow sunlight to assist with natural melting.
5. Consider Drainage System Upgrades
In homes with recurring problems, sump pumps, French drains, or even replacing outdated window well structures may be necessary. These upgrades move water away from the foundation and reduce the risk of repeated flooding.
Why Does It Matters in Fort Collins?
Colorado’s fluctuating temperatures and heavy snowfall create ideal conditions for ice dams and rapid snowmelt. If your window wells aren’t prepared, even one bad storm can lead to thousands of dollars in water damage.
Don’t wait until spring to find out your window wells weren’t ready.

FAQs About Window Well Drainage & Winter Flooding
Q1: How do I know if my window well drainage is frozen?
A: Signs include standing water that doesn’t drain, ice buildup inside the well, or visible cracks in the drainage layer. If your basement window fogs or leaks, the issue may already be underway.
Q2: Can I DIY fix a clogged window well drain?
A: Minor blockages can be cleared by hand or with a shop vac. However, if you suspect frozen pipes, crushed drainage, or structural issues, it’s best to call a professional.
Q3: What kind of cover should I install for winter?
A: We recommend custom-fit polycarbonate or metal window well covers. They keep snow, ice, and debris out while allowing light in and providing ventilation.
Q4: Is gravel really necessary in my window well?
A: Yes. A layer of crushed stone or gravel improves drainage and prevents pooling. Without it, water collects and increases the risk of freezing and basement leakage.
Q5: How often should I perform window well maintenance in winter?
A: Inspect your wells monthly and after every major snowstorm. Clear off snow and check for pooling water or ice accumulation.
