Leaks in any car are hateful.

At best, wet carpets and the nagging knowledge that corrosion might be occurring under your feet. At worst, you have to bale the car out before driving, get your wellies on or sit on a damp seat. Here’s how to deal with those pesky leaks.

First port of call in repairing car leaks is to get the whole interior removed – seats, carpets, door cars and pillar trims at the very least.
Once it is all removed you can dry it all out and clean off any mould or spores that have grown.

Next up is to dry the complete interior metalwork of the car.
Third, cover the inside of the car with a light dusting of talcum powder.
Finally, you can then soak the outside of the car with the spray from a hose, to replicate light rain, or a pressure washer to simulate a downpour.

This is where the talcum powder comes into its own. Any moisture ingress will be shown by the talc going darker as it wettens. You can see the dark patches and follow the line of wetness up to the point or points where the water is getting in, then deal with the leaks you find.

Leaks can happen from:

  • Failed rubber seals around windscreens
  • Inadequate plastic weather sheets behind door cards
  • Worn or torn door sealing rubbers
  • Corrosion
  • Blocked sunroof or plenum chamber drain pipes
  • Failed bonding where glazing is attached to the body
  • Lack of drains in floor
