Why is my windscreen leaking?

The most common causes are a failed or perished rubber seal around the windscreen, deteriorated bonding adhesive, or a poor fit from a previous replacement. Corrosion around the glass aperture frame can also cause leaks, particularly on older vehicles. Our technicians will diagnose the exact cause before recommending a fix.

Can a leaking windscreen be resealed rather than replaced?

In many cases, yes. If the glass itself is undamaged and the leak is caused by a failed seal or adhesive, we can reseal the windscreen without replacing it. Our technician will assess the situation and advise you on the most cost-effective solution.

Is a windscreen leak covered by insurance?

This depends on your policy. Some comprehensive policies include windscreen seal and leak repair. It's worth checking with your insurer, and we can also advise when we visit. If a full windscreen replacement is required to resolve the leak, that is often covered under windscreen insurance.

How long does a windscreen seal repair take?

A straightforward reseal typically takes 1–2 hours. If the windscreen needs to be removed and refitted, allow around 2–3 hours including adhesive cure time. Our technician will give you a specific estimate after diagnosing the issue.

What damage can a windscreen leak cause?

Over time, water ingress causes damp carpets and upholstery, mould growth, musty odours, rust in the floor and sills, and potentially serious damage to electrical wiring, control modules, and sensors. The longer a leak is left untreated, the more expensive it becomes to put right.

My windscreen was replaced recently and now it leaks — can you fix it?

Yes. A leak following a windscreen replacement usually indicates poor fitting or inadequate adhesive application. We can diagnose and correct the fault. If we carried out the original replacement, we'll put it right at no charge under our workmanship guarantee.
