Can a windscreen chip be repaired?

A windscreen is laminated, which means it is made in layers. A stone chip usually breaks only the outer layer. While it stays small, it can be filled. Water, grit, heat and cold can turn it into a crack, so the same chip may be a small job this week and a new windscreen later.

What kind of repair does it need?

Resin injection. Air is drawn out of the chip, clear resin is forced in and hardened. It leaves a faint mark. Repairers set their own limits. Some only repair chips smaller than a 5 cent coin in front of the driver, smaller than a one dollar coin elsewhere, and none within 5cm of the edge. Others repair chips up to a 20 cent coin.

Class of work Resin injected into the break. The screen is kept.

Only while the chip is fresh and small enough. It leaves a faint mark. Some policies repair chips with no excess, often as an optional extra. Check yours.

What to do next
