What Causes A Sliding Glass Door To Leak?

There are several common causes of sliding glass door leaks that homeowners should be aware of:

Worn Out Weatherstripping

One of the most common causes of sliding glass door leaks is worn out weatherstripping. Weatherstripping is the material that seals the gap between the sliding glass door and the frame.

Over time, weatherstripping can become brittle and crack, allowing water to seep through. To fix this issue, homeowners should replace the weatherstripping with a new, high-quality material.

Misaligned Door

Another cause of sliding glass door leaks is a misaligned door. If the door is not properly aligned with the frame, it can create gaps that allow water to seep through.

To fix this issue, homeowners should adjust the rollers on the bottom of the door to ensure it is level and properly aligned, otherwise you could find yourself with water coming under your door.

Damaged Or Dirty Tracks

Damaged tracks can also cause sliding glass door leaks. If the tracks are dirty, damaged, or clogged with debris, water can accumulate and seep through the gaps. Homeowners should regularly clean the tracks and remove any debris to prevent this issue. If the tracks are damaged, they should be repaired or replaced.

Poor Installation

Finally, poor installation can also cause sliding glass door leaks. If the door frame was not installed properly, it can create gaps that allow water to seep through. Homeowners should ensure that their sliding glass door was installed by a professional and that all gaps and weep holes are properly sealed.
