This page provides all the information you need about leaky basement windows: their causes, effects, and solutions. Equip yourself with the knowledge necessary to make the best decision for your home.

What Are Leaking Basement Windows? 

Leaky basement windows allow water to enter the indoor space. They are characterized by: 

  • Visible moisture marks 
  • Water staining 
  • Water accumulation around window frames 

Aging or damaged basement window systems are vulnerable to water pressure, which seeks the easiest route into your home. Leaking windows often lead to other problems, such as: 

Leaking basement windows can cause significant water damage in your basement and home, affecting both structural integrity and safety. If you observe any of these issues, it’s crucial to promptly reach out to local basement waterproofing experts like Baker’s Waterproofing to address the root of the problem. 

What Causes Leaking Basement Windows? 

The leading causes of leaking basement windows include: 

  • Material decay: Wood, metal, and vinyl window frames can corrode and rot over time, creating gaps that allow water to seep in. 
  • Poor installation: Improperly installed windows can leave gaps around the frame and sill, making them vulnerable to leaks. 
  • Age: Older windows are often less energy-efficient and more prone to leaks. 
  • Drainage problems: If the drainage system around your basement window well is clogged, water can back up and seep into your home. 
  • External pressure: Hydrostatic pressure from expansive clay-based soil can force water through even the smallest openings in your foundation walls. 
  • Climate conditions: Heavy rains, snow, and seasonal changes can put additional stress on basement windows and make them more likely to leak. 

Since these issues can be intricate, precise diagnosis is essential for effective repairs. Contact Baker’s Waterproofing for a comprehensive, complimentary inspection.
