Different expansion and contraction rates of different types of materials at different temperatures cause gaps. The frame of the window that can be made of wood or vinyl expands at different rates than the wood wall framing and the brick exterior wall surfaces, depending on the temperature or humidity of any particular day. Gaps also take place around the windows of old homes. After years of extreme temperatures, varying weather conditions, and building settling, windows are no longer air or water-tight. Modern or new windows are said to be maintenance free but still, sometimes there remain gaps around windows or the window leaks. Newly constructed windows are also prone to water intrusion. No matter how strong the window material is made of, it still won’t last forever and start leaking eventually. Water is very much corrosive to a home, and even harmless-seeming leaks can lead to mold development, structural damage, or both. It is now clear that if there’s a gap between the windowpane and the frame it is a defective window, that has been manufactured incorrectly or there can be many reasons that we will discuss in this blog later.
Causes for Gaps Around Windows
- Lack of overhangs to drain water off the roof helps rainwater from entering through the windows.
- Improperly angled fascia board above the window can cause water to seep in. It should be angled outward to direct water away from the unit.
- Water leaks at windows also result from a breakdown in the connection between the window frame and the wall.
- In the case of older homes, buildings “settle” over time, and years of fluctuating temperatures and weather conditions cause wood to shrink and expand, sometimes shifting a window inside its frame and creating gaps around windows.
- Improper installation can allow water intrusion.
- Compromised sealant such as broken caulking at the window seams, cracked glazing putty between panes, and an inadequate paint seal along the edges of the glass can all lead to water infiltration.
- Gaps around windows are also caused by Foundation Problems.
How to determine where the leak is coming from?
Light a candle around the windows that you think have leaks. If the flame dances flickers, then it is confirmed that there is a leak.
Your walls may still look new and fresh but if there is an evident pattern of rot, or even mold reaching all the way up the wall, be confirmed that there is a gap/leakage.
Leaks at the top or bottom of the window are often a result of leakage in the structure.
If you notice water entering where the glass meets the sill, be assured there is a leakage.

Few ways to fix it
- To ensure proper adhesion, remove any old caulk and paint. Make sure the area is free from dust, grease, and loose/flaking paint.
- For a neater finish and easier cleanup, you can tape both sides of the gap before applying the particular product.
- No paint seal—the paint should slightly overlap from the window molding to the glass to create a tight seal.
- Make sure the sill at the bottom of the window frame is pitched downward to drain water toward the exterior.
