Causes of Window Leaks
- Faulty Installation: Incorrect placement or improper sealing techniques during installation can create gaps, allowing water to seep through.
- Worn Seals and Weatherstripping: Over time, seals and weatherstripping around windows deteriorate due to exposure to the elements, compromising their ability to block out water.
- Poor Waterproofing: Inadequate application of waterproof membranes and sealants during construction or renovation leaves windows vulnerable to leaks.

Identifying Window Leak Sources
Accurately identifying the sources of window leaks is critical to effectively addressing and repairing them. The primary methods used to pinpoint these issues are the following:
Visual Inspections
Visual inspections involve a thorough examination of the window and surrounding areas to identify obvious signs of leaks. This includes checking for water stains, mold growth, and deteriorated seals or weatherstripping.
Moisture Detection Tools
Moisture detection tools, such as moisture meters and infrared cameras, help detect hidden leaks that are not visible to the naked eye. These tools measure the moisture content in and around window frames, highlighting areas of water intrusion.
Structural Assessments
Structural assessments evaluate the integrity of the building and how shifts or settling might be affecting the windows. This involves checking for misalignment, gaps, and cracks that could be allowing water to seep in.

Risks and Damages from Window Leaks
Understanding the risks and damages associated with window leaks is crucial for timely and effective remediation. Here are the key issues that can arise:
Water Damage to Interior Walls and Floors
Water damage to interior walls and floors occurs when leaks allow water to seep into the building’s interior. This can cause staining, warping, and deterioration of materials such as drywall, wood, and flooring.
Mold and Mildew Growth
Mold and mildew growth is a common consequence of prolonged moisture exposure from window leaks. These fungi thrive in damp environments, posing health risks and further damaging building materials.
Reduced Energy Efficiency
Reduced energy efficiency results from compromised seals around leaking windows, allowing drafts and temperature fluctuations. This can lead to higher heating and cooling costs as your HVAC system works harder to maintain a comfortable indoor temperature.
Compromised Structural Integrity
Compromised structural integrity can occur when water infiltration from window leaks weakens the building’s framework. Continuous exposure to moisture can lead to wood rot, rusted metal components, and weakened support structures.
