Leaking Basement Windows

Here at The Basement Guys, we specialize in basement waterproofing services that fix leaky basement windows, providing value and peace of mind. These customizable and durable solutions are far more effective than a traditional repair job, letting you enjoy your downstairs space for years to come.

Below, you’ll learn the causes and effects of basement windows that leak and how to fix them.

Understanding Leaking Basement Windows

When basement windows leak, water can damage your home. That’s why you need to solve this issue immediately. You can identify leaky windows in your basement by:

  • Excess moisture
  • Water stains 
  • Puddles around window structures

The older your basement windows are, the more likely they will leak. If you ignore this problem, the following could happen:

  • Wet basement walls
  • Intruding water
  • Mold growth
  • Efflorescence on concrete surfaces
  • Increased basement humidity
  • Musty odors

In worst-case scenarios, leaking basement windows can destroy the structure of your property, risking the safety of everyone in your home. If you notice any of the above signs, contact The Basement Guys for an immediate and detailed inspection.

What Causes Leaking Basement Windows?

Basement windows can leak for various reasons, including:

  • Poor Installation: Openings can appear in incorrectly installed windows, allowing water to enter your basement. 
  • Age: Older windows are more likely to leak because of temperature fluctuations and general wear and tear.
  • Elements: Adverse weather here in Ohio can degrade the windows in your basement, resulting in leaks. 
  • Exterior Pressure: Hydrostatic pressure from saturated, expansive clay-based soils can push water through cracks in basement windows.
  • Drainage Problems: Water often accumulates in basement window wells, causing internal leaks.
  • Material: Wood, metal, vinyl, and other materials are vulnerable to corrosion and decay, increasing the likelihood of leakage. 

It’s difficult to identify the cause of leaky basement windows yourself. So, consider calling in the experts at The Basement Guys for a free and comprehensive evaluation.
