Classic and Older Car Windscreen Replacement in Sydney

Classic and Older Car Windscreen Replacement in Sydney

Replacing the windscreen on a classic or older car is a different job from a modern one. Many older vehicles hold the glass in with a rubber seal rather than bonding it to the body with urethane, and finding the right glass can take more planning.

Rubber-Seal vs Bonded Windscreens

Most modern windscreens are bonded: glued to the body with a urethane adhesive so the glass becomes part of the car’s structure. Many older cars use a rubber-seal (gasket) windscreen instead, where the glass sits in a rubber channel that grips both the glass and the body opening.

• Rubber-seal: the glass and seal are fitted together into the opening, and the seal is pulled over the body flange. The seal itself must be in good condition to stop leaks.
• Bonded: the glass is set onto a bead of urethane on the pinch weld and the adhesive must cure before the car is driven. See how bonded windscreen replacement works.

The Rubber Seal Usually Needs Replacing Too

Old rubber hardens, shrinks and cracks with age and sun. Reusing a perished seal often leads to leaks or the glass sitting poorly, so a new seal is often part of the job. Seals for popular models are usually available; rarer models can take time to source.

Sourcing the Glass

For common older models, replacement glass is often still available. For rarer or very old vehicles, the glass may need to be sourced from specialist suppliers, which can take time and cost more. When you ask for a quote, give the make, model, year and body style, and a photo of the glass marking if possible — see car glass markings explained.

Check the Frame Before You Book

On older cars, rust in the windscreen opening is common. Corrosion under a rubber seal can be hidden until the glass comes out, and it may need panel repair before the new glass goes in. See rust under the windscreen for the warning signs.

Laminated Glass Matters

Windscreens are laminated so the glass holds together when it breaks. If an older car still has its original windscreen, ask what type of glass will be fitted as a replacement and make sure it carries the appropriate standards markings. Our article on laminated vs toughened glass explains the difference.

Frequently Asked Questions

Can a rubber-seal windscreen be done as a mobile job?

Often, depending on the vehicle and conditions. Contact us with your details and we will confirm.

Can a rubber-seal windscreen be converted to bonded?

Not as a simple windscreen job. The body opening and glass are designed for one method, so it is best to stay with the original design.

Why does my older car leak around the windscreen?

The most common cause is a hardened or shrunken seal. Rust in the opening is the next most likely. See why a windscreen leaks after rain.

How much does a classic car windscreen cost?

It depends heavily on glass and seal availability for your model, so it is quoted per vehicle. See our windscreen cost guide for the factors involved.
