Is your windshield leaking? Whether your windshield leaks when it rains or you've just noticed a leak in the car wash, leaks are bad news!

Unfortunately, a windshield that appears fine may spring a leak tomorrow or at any time. To make matters worse, a leak may go unnoticed for weeks, even months because leaks often begin with few symptoms and grow worse over time.

A little water seeping onto the top of your dash might seem like no big deal, but it can cause major problems without intervention. Luckily, we've got you covered with our top tips for identifying and understanding the causes of windshield leaks when it rains.

Why Is My Windshield Leaking When It Rains?

Understanding what causes your windshield to leak is the best way to begin your windshield leak repair and to prevent future problems.

Top leak-causing culprits include:

  • Faulty rubber seals around the windshield can be caused by age and deterioration.
  • Mold and mildew growth on windshield seals or between the seal and glass.
  • Improperly installed windshields.

It's also essential to recognize the symptoms of a leaky windshield so that you can catch the leak at the first sign of an issue – or the first sign of rain.

Common symptoms of a chronically leaking windshield include:

  • Mildew or mildew smells inside the vehicle.
  • Fog on the inside of the windshield.
  • Windshield rust.
  • Discoloration.
  • Wet carpet or upholstery.

Windshield Leak Repair: A Job for the Professionals

The windshield is more than a window; it's an integral part of the structure of your car and the safety systems that protect you and your passengers. If your windshield is leaking, you’ll need the the assistance of a professional like your local Glass Doctor®.

When you work with your local Glass Doctor to fix a leaky windshield, our service professionals will advise you as to whether or not your windshield may be repaired or if the degree of damage requires a replacement. Depending on the damage, it may be possible to reseal the windshield. Most windshields are held in place and sealed with the combination of a gasket and liquid sealant.

When resealing a windshield, our service professionals follow this process:

  1. Carefully remove exterior trim pieces.
  2. Locate the leak beneath the trim.
  3. Thoroughly clean the area.
  4. Apply a new, liquid sealant overtop the leak.
  5. Test the fix.
  6. Let dry.
  7. Replace exterior trim pieces.

If resealing is not possible, your Glass Doctor will help you understand other options, including replacement of the rubber gasket and replacement of the entire windshield.

FAQ About Why a Windshield Leaks

Experiencing a windshield leak is frustrating, but we’re here to make it easier! We’ve answered the question “why does my windshield leak during the rain” but we have more answers. Read on to learn more and reach out if you want to schedule a windshield water leak repair service.

I have a water leak after windshield replacement. Is this common?

No, it is not common to experience a water leak after windshield replacement. This indicates that the windshield installation was not done properly. Common causes of a leaky windshield after replacement include insufficient or uneven sealant application or missing spots in the urethane bead.

If you notice a windshield leak after a replacement, reach out to a Glass Doctor glass specialist in your area. We can promptly resolve this issue and install a replacement windshield correctly.

Is a car side window leak repair the same as a windshield leak repair?

While both repairs involve resealing the windshield glass to prevent water entry, the techniques and materials can differ. Windshield leaks usually involve the seal around the glass, while side window leaks often relate to worn or damaged weatherstripping or window tracks. Both require identifying the source and resealing, but the specific repair steps and materials may vary.

Is a leaking windshield covered by insurance?

Coverage for a leaking windshield depends on your insurance policy. Some comprehensive auto insurance policies may cover windshield repairs or replacements, especially if the leak is due to an accident. Review your policy details or contact your insurer to confirm your coverage.

Don't forget to document the damage with photos and dates to support any claim. Glass Doctor is available to help submit claims on your behalf.

How can I tell if my windshield is leaking?

You should look out for these common signs to determine if your windshield is leaking:

  • Musty or damp odor inside the vehicle
  • Foggy windows from the inside
  • Wet carpets, upholstery, or dashboard
  • Visible rust or water stains around the windshield area
  • Mold or mildew growth

What is a temporary fix for a leaky windshield until I can get it repaired?

For a quick temporary fix for a windshield that is leaking from rain:

  • Find the source of the leak.
  • Dry the area thoroughly.
  • For major leaks, protect your car’s interior from water damage.
  • Apply waterproof tape or plastic sheeting over the leak.
  • Keep the car covered and avoid car washes.
