Preventing Window Leaks: Can Periodic Cleaning Make A Difference?


Windows are the eyes of the house, letting in light and providing a view to the outdoors. But, when they start to leak, that view is quickly replaced with worry and frustration. Vancouver, WA gets a lot of rain, and if your windows aren’t sealed properly, you may be wasting money on heating, cooling, and energy bills. However, there is a simple step you can take to prevent window leaks: periodic cleaning.

In this blog post, we’ll discuss how regular cleaning of your windows can make a significant difference in preventing leaks.

1. Keep the home’s window seals clean

The rubber seals around your windows are designed to prevent leaks by sealing the space between the frame and the glass. However, debris like dirt, dust, and dead leaves can accumulate in these seals over time, preventing them from doing their job correctly. Clean the seals with a soft-bristled brush regularly to keep them in good condition.

2. Stay vigilant

Don’t wait until you notice water damage or draftiness to check for leaks in your windows. Regularly inspect each window for signs of moisture around the frame, or draftiness when it’s closed. If you notice any of these signs, call a professional to repair the sealant around your windows to prevent leaks.

3. Clean the weep holes

Weep holes are small openings in the frame of your windows that allow moisture to escape. But, if they get clogged with debris, they can cause water to accumulate inside the frame, leading to leaks. To prevent this, use a small brush or toothpick to clean out the weep holes regularly.

4. Keep gutters and downspouts clean

Clogged gutters and downspouts can cause water to overflow onto your windows, leading to water damage and leaks. Regularly clean out gutters and downspouts to prevent this from happening.

5. Not all cleaning methods are created equal

Be careful when cleaning your windows, as certain chemicals or methods can damage the seals and cause leaks. Always use a non-abrasive cleaning solution and a soft cloth or sponge. Avoid pressure washing or harsh chemicals that can damage the seals.


Keeping your windows clean not only makes a noticeable difference in the appearance of your home, but it also plays a significant role in preventing leaks.

By taking proactive measures like cleaning the seals, inspecting your windows, maintaining weep holes, cleaning gutters and downspouts, and using gentle cleaning methods, you can prevent water damage and enjoy a comfortable, energy-efficient home. If you do notice any leaks or signs of damage to your windows, don’t hesitate to call a professional to repair the problem promptly. By taking these steps, you can ensure your home is protected against the elements and enjoys a beautiful view for years to come.
