A leaky window isn’t just a nuisance—it can cause serious water damage, raise energy bills, and compromise the comfort of your home. If you’re noticing drafts, foggy panes, or visible water stains, it’s time to take a closer look. At Ainger Windows & Doors, we help homeowners across Barrie identify and solve window issues before they turn into costly repairs.
Here are 7 common reasons why your windows are leaking—and what to do about them.
1. Poor Window Installation
One of the top reasons windows leak is improper installation. If your windows weren’t sealed or flashed correctly, water can seep through gaps and cause damage behind the walls. At Ainger Windows & Doors, we offer professional installation to ensure a secure, weatherproof fit every time.
2. Worn or Damaged Seals
Over time, the seals around your window panes can dry out, crack, or shrink—especially in Barrie’s extreme temperatures. Once compromised, these seals allow moisture to creep between panes or into the frame, leading to leaks and foggy glass.
3. Clogged or Improperly Sloped Window Tracks
If you have sliding or double-hung windows, clogged tracks or debris buildup can prevent proper drainage. This causes water to pool and eventually leak into your home. Regular maintenance and proper design slope are key to preventing this.
4. Cracked Window Caulking
Caulking is your window’s first line of defense against the elements. But caulk deteriorates over time due to sun exposure and seasonal expansion and contraction. Re-caulking your windows can help seal out moisture and air leaks.
5. Damaged or Rotted Window Frames
Wooden window frames can absorb moisture, warp, or rot—especially if they’re not properly painted or sealed. Damaged frames can no longer hold a tight seal, allowing rain and melting snow to leak through.
6. Condensation Buildup from Poor Insulation
Excess condensation on the inside of your windows may signal poor insulation or broken thermal seals. This moisture can eventually lead to mold, mildew, and even water damage. Upgrading to energy-efficient, double- or triple-glazed windows helps solve this issue.
7. Improper Flashing Around Windows
Flashing directs water away from critical joints around your windows. If flashing is missing or installed incorrectly, water can easily seep into the walls during rainstorms or snow melts—a common issue in homes across Barrie.
