Leaking windows can cause serious damage to your home and significantly increase your energy bills. But before you panic and start searching for window replacement in Canada, take a moment to be proactive. Try to figure out where the leak is coming from—you might even be able to fix it yourself!
From improper installation to weather-related wear, this guide explores the top five reasons behind window leaks and offers actionable steps to fix them.
1. Poor Installation
Improperly installed windows are one of the leading causes of water intrusion around windows. Without proper alignment, waterproof tape, or sealing, gaps can form around the window frame, allowing water to seep into your home. Additionally, inadequate setup compromises your home’s energy efficiency.
Signs of Poor Window Installation
– Water pooling at the base of the window frame during downpour.
– Drafts of cold air entering your home through gaps in the window.
– Visible signs of condensation on the window sill.
How to Fix It
– Reinstall the Window Properly: A professional installer can correct faulty installation, ensuring the window is tightly sealed with waterproof tape and house wrap.
– Apply a Tight Seal: Use a caulking gun to seal any gaps around the frame.
– Address Faultily Installed Windows: Ensure the frame is correctly aligned and secured to prevent future leaks.
2. Worn-Out or Damaged Seals
Over time, the seals around your window may crack or peel, leading to window water damage, drafts, and reduced energy efficiency.
Signs of Damaged Seals
– Condensation forming between glass window panes.
– Water drips around the edges of the window frame.
– Drafts of cold air coming through the window.
How to Fix It
– Replace the Seals: Use a utility knife to remove damaged seals and replace them with weatherproof alternatives.
– Reinforce with Glazing Compound: Apply glazing compound around the window to ensure a tight seal.
– Inspect for Future Leaks: Regularly check seals for cracks, especially after heavy rain or harsh weather conditions.
Keep in mind that properly sealed windows prevent leaks, reduce energy loss, and improve your home’s comfort in the long run.
3. Damaged Window Frames
The window frame is critical to preventing leaks. Over time, wooden frames may rot, while metal or vinyl frames can crack or warp, creating opportunities for water to enter.
Signs of Frame Damage
– Warping or discoloration around the frame can help avoid window leaking.
– Mold growth caused by prolonged moisture exposure.
– Gaps or openings where the window frame meets the wall.
How to Fix It
– Repair Minor Cracks: For wooden frames, use wood filler or epoxy to repair cracks. Sand and paint the frame to protect it from leaks.
– Replace the Frame: Frames made of vinyl or metal are more durable and resistant to moisture.
– Inspect Around the Window Frame: Check for gaps or damage regularly to prevent a potential leak.
4. Improper or Missing Flashing
Flashing tape and house wrap are essential to redirect water away from the seals and fix a leaking window. Missing or improperly installed flashing can cause water to seep into the walls, leading to structural damage.
Signs of Flashing Issues
– Persistent water leak during intense rainfall.
– Water pooling near the base of the window.
– Gaps around the window sill.
How to Fix It
– Install Waterproof Tape: Properly apply window seal tape in overlapping layers to direct water away from the window.
– Add a Sill Pan: A sill pan provides an extra layer of protection against any leak.
– Address Specially Designed Window Flashing: Make sure flashing is installed according to the manufacturer’s specifications.
5. Weather-Related Wear and Tear
Have you ever woken up one morning and noticed that your window is leaking out of the blue? Nature might be to blame. Extreme weather conditions, such as pouring rain, snow, or fluctuating temperatures, can wear down your windows over time. High winds may cause cracks in the seals or frame, while moisture buildup can lead to a water leak.
Signs of Weather Damage
– Water stains around the window frame after a rainstorm.
– Peeling paint or discoloration caused by moisture damage.
– Mold is growing around the edges of the frame.
How to Fix It
– Upgrade to High-Performance Windows: These windows are designed to withstand extreme weather and improve energy saving.
– Clear Weep Holes: Ensure weep holes are free of debris to allow water to drain properly.
– Reinforce Seals: Use a glass seal around the window frame to avoid windows leaking proactively.
Preventative Tips to Stop Window Leaks
Taking proactive steps can protect your home from water damage and ensure your windows remain leak-free.
1. Inspect Regularly: Inspect leaking window for signs of damage, such as cracked seals, warped frames, or water leaking around the edges.
2. Maintain Weep Holes: Clear debris from weep holes to prevent water pooling.
3. Use Durable Materials: Install high-performance windows with metal or vinyl frames for added durability.
4. Apply Flashing Tape: Properly installed window seal tape can help you fix a leaking window as well as proactively avoid the problem in the future.
