Why Are My Basement Windows Leaking?

Your basement windows are exposed to more moisture than you might think over the course of a single year. If you have window wells in place, your basement windows are in the perfect position to find themselves exposed to not only standing water but a significant amount of hydrostatic pressure, which may cause them to burst at the seams over time.  

• Common Causes Behind Basement Window Damage 

That said, it isn’t just hydrostatic pressure that can cause your windows to leak. Some of the other common causes of basement window damage include: 

• Errors during home construction 
• Errors during window installation 
• Freezes 
• Pipe damage 
• HVAC system damage 

Even something as simple as poor grading can put your windows at a higher degree of risk for damage. The grading around your yard—whether or not your home sits at your lawn’s highest or lowest point—will direct water away or toward your perimeter. If you happen to live in a low spot, you may be more likely to see water-damaged windows than your neighbors. 

• Getting Ahead of Basement Window Leaks 

The good news is that you can work with area professionals not only to repair damaged basement windows but also to get ahead of the damage that might cause them to start leaking again. Home waterproofing measures are the ideal protective barriers to put into place if you want to prevent your windows from letting moisture into your home. Some of the most effective to install for window safety include: 

• Interior drainage system 
• Sump pumps 
• Vapor barriers 
• Dehumidifiers 
• Waterproof insulation 

Note that no waterproofing measure lasts forever. You’ll want to schedule annual home inspections to ensure that your waterproofing measures are still operating as they should. The experts in your area can also look over your windows during these annual check-ins to make sure that any initially conducted repairs are still serving your home as they should.
