How can a leaking windscreen be fixed?

If you’re looking to find out how you can fix your leaking windscreen, you’ve probably had the nasty shock of finding moisture, mildew and maybe even a pool of water on your dashboard. It might be the case that you noticed these signs a while ago but the penny only dropped whilst you were on a long journey with heavy rainfall or whilst going through a car wash.

This month, 1st Call Windscreens are here to help you find the root of the cause and the best windscreen leak repairs. These include quick fixes such as duct tape, re sealing the corners, resin injections into cracks and chips and window screen replacement.

Find where the problem lies

There are multiple ways moisture can find its way into a vehicle, whether that’s through the doors, sunroof, side windows, air conditioners, boot or windscreen – it’s important to find the cause. The best way to find out is to check your car over.

For your doors, sunroofs and side windows, you will need to check the seals around the edges, it can be the case that the seal has worn away and needs replacing. It might also be the case that your air conditioner is broken, when this breaks it doesn’t filter the water to the outside like it should and instead causes a leak inside the vehicle. Of course, to test this, turn on your air conditioner to see if it works. These checks need not take long because they will generally show obvious signs that they’re allowing moisture into the car. Once you have ruled out these possibilities – you know that it’s down to your windscreen.  

A little leak won’t hurt?

A common misconception people have is that a little chip or broken seal couldn’t possibly affect a vehicle a great deal but this really isn’t the case. A buildup of moisture can cause a whole array of unpleasant effects such as discolouration, bad odours and mold – it can even have an effect on the electricals inside the vehicle – which you really need to steer clear from! 

Check for the leak on your windscreen

Place a towel over your dashboard and cover all electrics and have someone sit inside the car whilst you pour water across your windscreen. Start by spraying around the seals and then make your way over the whole of the window to ensure you have completely covered it in water. Of course, when you’re done you will be able to check the towel you have placed down and your friend will be able to tell you where the leak is coming from. 

Methods of windscreen leak repair

  • Duct tape – if your problem lies around the seal of the windscreen, duct tape is a quick but obviously not permanent solution that’ll keep your car safe whilst you wait for professional attention. Use duct tape accordingly, as you can’t do this to a chip in the middle of the screen for visibility/legal reasons.
  • Re sealing – the cause should be visibly obvious, the seal around the edges of your windscreen will have worn away. You will need to contact a professional who will ensure a safe and secure re seal.
  • Resin injection – is an effective windscreen leak repair that’ll sort a chip or crack, instead of having to completely remove and replace the windscreen.
  • Replacement – depending on how bad the leak is, it might be the case that you need a full windscreen replacement. It’s important to get a team of professionals to take a look at your vehicle to ensure they choose the right windscreen leak repair method.
