Most Dangerous Windscreen Leaks to Look Out For

A windscreen leak might seem like nothing more than a small inconvenience, but if ignored, it can lead to serious problems. At The Windscreen Company, we’re experts in windscreen repairs and replacements, and fixing leaking windscreens is part of our comprehensive service. 

In this article, we’ll outline some of the most dangerous windscreen leaks you should be looking out for.

Why windscreen leaks are dangerous

Even a small windscreen leak can cause a major problem if you do not get it fixed. Here are a few reasons why you should always address a leak as soon as possible:

  • Reduced visibility – Moisture in your car can cause condensation or fog up the glass, which makes it hard to view the road ahead. Not having a clear view of the road is also illegal when driving.
  • Electrical risks – Water can impact your car’s electrics, causing damage and creating a hazard. 
  • Mould and odours – Damp carpets and fabrics from leaks can become a breeding ground for harmful bacteria. 
  • ADAS interferences – Leaks near cameras and sensors can cause them to become damaged and prevent them from functioning properly. 
  • Structural integrity – A leak can reduce the structural integrity of your entire windscreen, meaning it may be at risk of complete failure.

Quick checks: is it really the windscreen?

Dampness or water in your car may not be a windscreen seal failure. There are a few things to rule out first, including: 

  • Blocked scuttle drains
  • HVAC drain blockages 
  • Leaking roof membranes or window seals
  • Sunroof issues

Most dangerous windscreen leaks

types of windscreen cracks and chips

If your windscreen is the problem, then it’s imperative you seek professional help as soon as possible. Some examples of the most dangerous windscreen leaks include:

Perimeter bond / seal failure

The most common cause of windscreen leaks is when old adhesive corrodes along the pinch weld or has been poorly installed. Signs of this problem include:

  • Damp headlining 
  • Water trickling down the A-pillar 
  • Moisture under the dash

If ignored, the windscreen can fully detach when you’re driving.

Cracks and chips 

Even a small chip can allow water to enter the vehicle. A temporary, DIY sealant is sometimes attempted, but these often fail as they will not adhere to the glass properly. A full windscreen replacement is the only lasting solution in these situations. 

A-pillar and scuttle panel leaks 

Misaligned cowling panels, missing trim clips and damaged pollen filter housings can all cause these leaks, which will make water drip into the front footwells.

Rain sensor / ADAS camera housing leaks

Disturbed housing or gels can cause fogging around the mirror area and damage ADAS. Any work involving ADAS will require a recalibration, and this is something we offer as standard as part of these jobs.  

Aftermarket add-ons causing ingress

Dashcam wires, adhesive mobile phone mounts and other add-ons to your car can damage seals or trap moisture on your windscreen. This can indirectly cause leaks, so it’s important to properly install these accessories to avoid problems. 

Previous poor rebond or non-OEM materials 

Substandard adhesives or uneven beading on your windscreen can cause leaks. At The Windscreen Company, we use a specialist adhesive with unrivalled 30-minute drive-away times.

 

Symptoms to watch: misting, damp headliner, wet carpets

Some common signs of a windscreen leak include:

  • Damp or musty smells
  • Condensation on your glass
  • Wet carpets
  • Water on your dashboard
  • Fogging behind the mirror
