Weathering storms: window leak prevention
You shouldn’t ignore a window leak. Ongoing water damage may lead to window replacement if not taken care of. We will help you understand the causes of window leaks, teach you some actions to prevent them, and share some waterproofing solutions for your windows.
Understanding window leak causes
Some common causes of window leaks are:
- Bad angles – Windowsills and facia that tilt toward the window instead of away from it
- Damaged or missing sealant – The most common cause of water leaks
- Improper installation – Including low-quality materials
- Lack of overhangs – To protect the window from wind and water
- Wall leaks – Sometimes window leaks are actually wall leaks
It’s not just wind and water that can affect window leaks; it’s the temperature as well. Cold temperatures can cause shrinking and contracting of the window frame, which can warp its structure. You may notice this if your window doesn’t open or close easily. In addition, warm temperatures cause expansion, which can also warp window frames and cause window locks to jam.
Preemptive actions to prevent leaks
Make window inspection and maintenance part of a yearly routine when inspecting your house. We suggest the following simple actions:
- Look for mold or mildew signs
- Inspect locks and windows for smooth opening
- Check screens for rips or tears
- Review seals for gaps or cracks
- Look at the window frame for rot or cracks
- Study windows for loose screws
- Scan your windowpanes for moisture
It may be best to upgrade to higher-quality window materials if you notice a leak, especially if your windows are old. Not only will the replacements stop leaks, but you will also save on your energy costs.
Weatherproofing solutions for windows
Before you upgrade your windows, consider resealing them or installing new weatherstripping. Some air leaks are easy to spot, and some are not. Another idea is to turn off your lights during the day to see if daylight is coming through where it’s not supposed to. Renting a thermal camera is another good option.
How to reseal your window:
- Remove old caulk and paint with a putty knife.
- Clean the area with soap and water and let it dry.
- Apply caulk at a 45-degree angle in a continuous stream.
- Reapply where necessary.
How to install weatherstripping:
- Clean the area where the weatherstripping will go and let it dry.
- Measure your window’s width and cut the weatherstripping to that length.
- Apply the weatherstripping to both sides, making sure that it forms a seal when the window is closed.
