A leaking windshield may seem like a small, annoying thing, but make no mistake – it can quickly become a serious problem. Research confirms that laminated automotive glass is not just for visibility but acts as a structural safety barrier, protecting passengers during rollovers and collisions.1 When the seal around your windshield is compromised, water intrusion can damage your car’s interior, create mould problems, and weaken the vehicle’s overall safety. Acting quickly can save you from expensive repairs and health risks.
Temporary Fixes Before Professional Help
When you discover a leaking windshield, your first step should be to stop water from entering until you can arrange proper repairs. Temporary fixes are meant to minimize damage, but they are not a long-term solution. They can buy you time and protect your vehicle’s interior from immediate harm.
The following are common temporary fixes for a windshield leak:
| Temporary Fix | How It Works | When to Use | Notes |
| Clear Silicone Sealant | Seals gaps around the leak by creating a waterproof barrier. | Small leaks along edges or seals. | Clean and dry the area first for better adhesion. |
| Waterproof Tape | Covers small chips or cracks to block water entry. | Quick emergency fix in rainy conditions. | Use automotive-grade or weather-resistant tape. |
| Windshield Repair Kit | Resin fills minor chips and cracks to reduce leak risk. | Small chips or short cracks. | Slows crack spreading, but it is temporary. |
| Clear Nail Polish or Super Glue | Provides a thin layer of protection for tiny chips. | Emergency fix when no other tools are available. | Wears off quickly and needs replacement. |
These methods help reduce water ingress, especially when the windshield leaks when it rains. However, they don’t fix the root cause. Over time, adhesive degradation or structural issues can worsen. Treat these fixes as stopgap measures and arrange for windshield leak repair by a professional as soon as possible.
Symptoms of a Leaking Windshield
Common symptoms of windshield leaking include visible moisture or condensation inside the car, especially when it hasn’t rained. You may also notice wet carpets, water stains near the dashboard, or rust around the windshield frame.
Another telltale sign is a persistent musty smell, which suggests mould or mildew growth. Increased wind noise while driving often indicates that the seal is compromised and no longer providing an airtight barrier.
Leak Detection Quick Tests
Once you suspect a leak, identifying the exact source is important. The soapy solution test is one easy method. Apply soapy water around the windshield edges, turn your car’s blower on high, and look for bubbles forming where air escapes.
Another option is the hose test. Have someone sit inside while you gently spray water around the windshield. If water enters the cabin, you’ve found the problem area. These methods are simple but effective for confirming whether the leak is coming from the windshield or elsewhere.
Common Causes of Windshield Leaks
A leaking windshield can result from various factors. Poor installation is a frequent cause, especially if the adhesive was applied unevenly or with low-quality materials. Environmental conditions, like harsh Canadian winters and UV exposure, can also break down sealants over time.
Physical damage is another common culprit. Chips or cracks may seem harmless at first, but can quickly expand, creating openings for water. If you notice a windshield leaking after replacement, it often points to improper installation or inadequate bonding.

Insurance Considerations
Many drivers wonder if a leaking windscreen is covered by insurance. In many cases, comprehensive policies cover repairs or replacements caused by road debris, weather damage, or accidents. However, coverage depends on your policy, so it’s best to confirm with your provider. Acting quickly can also prevent further damage that may not be covered, such as mould or corrosion.
The Risks of Ignoring a Leak
Delaying repairs can lead to bigger problems. Mould and mildew thrive in damp interiors, which Health Canada notes can cause respiratory issues, allergic reactions, and even asthma complications. Moisture can also damage carpets, upholstery, and electronic components.
In addition, prolonged leaks accelerate rust formation around the frame, reducing your car’s safety and resale value. Addressing a leaking windshield promptly avoids these costly and potentially dangerous outcomes.
