The majority of window leaks are caused by a breakdown in the chemical components of the sealant. This shows as degraded sealant is condensation found around the edge of the window when it rains. You can also look for discoloration or abrasions on the sealant itself. Windows leaking at the bottom corner of the frame or where the glass meets the sill typically indicates cracked caulking or glazing. Caught early, this issue can usually be repaired by stripping the old sealant and replacing it.
1. Sealant
One of the most common reasons people discover leaking windows during rain is damaged or missing sealant or caulk. Caulking is one of the simplest and most overlooked causes of window leaks. Any damaged caulk around the exterior of the window should be cleared out and replaced with a new bead of silicone caulk. This will ensure that air and moisture can’t get into cracks around the window’s exterior. In addition to stopping window leaks, this will also help keep heating and air conditioning bills lower in the winter and summer months.
2. Condensation
Sometimes the water that you see on your windowpane or sill isn’t rain at all, it’s condensation. Condensation forms on windows when the warm air inside your home encounters cooler air from outside your home. This is commonly caused by poor insulation around your windows. Additionally, you may get condensation between the panes if the seal around your glass is damaged. This will allow the argon gas between the panes of glass to escape, removing a form of insulation from your window. Regardless, condensation can cause damage like rainwater. It is also a sign of a poorly insulated or ventilated home.
3. Broken Window Seal
Through time, window seals can break. This is usually due to wear and tear. Broken window seals can be a result of the following:
- Cracked caulking; and/or
- Flattened or worn out weatherstripping.
Cracked caulking or failing weatherstripping can cause air leaks and heat loss. Furthermore, when such window seals are broken, they can allow rainwater to seep into the house.
4. Rotting Wood
When it rains, water may come into your house and continue to soak specific areas. Because of this, wood etc will cause decay and deterioration. This can happen anywhere in the home and cause issues.
5. Clogged Gutters
Clogged gutters can cause window leaks. This is mainly because they will overflow if clogged and cause water to back up into the house. Making sure that water can flow through and stay off the house is important.
