Scratched glass is frustrating — and at first glance, it might look like the only solution is to replace the pane entirely. But in many cases, scratched glass can be repaired on-site by a specialist, saving you significant cost and disruption. Here’s what you need to know.
Can All Glass Scratches Be Repaired?
The short answer is: most can, but not all. The key factor is the depth of the scratch.
- Light surface scratches — caused by grit, keys or cleaning products — can usually be polished out completely
- Medium depth scratches — caused by tools or debris — can often be significantly reduced or made much less visible
- Very deep scratches or chips — that go through the full thickness of the glass — may require replacement
A specialist technician can assess the scratch and tell you whether repair is feasible before any work begins.
How Is Scratched Glass Repaired?
Glass scratch removal uses a process called glass polishing. The technician applies a cerium oxide polishing compound to the scratched area and uses a polishing pad to gradually buff out the scratch. This process works by very slightly reducing the surface of the glass around the scratch, levelling it out until the scratch is no longer visible.
The process requires skill and patience — over-polishing can create a distortion effect (known as “optical distortion”) where the glass appears wavy when looked through. A trained technician knows how to avoid this.
What Types of Glass Can Be Polished?
- Float glass (standard window glass)
- Toughened or tempered glass
- Laminated glass
- Mirror glass
- Glass shower screens
- Glass doors
- Glass table tops
Note: specialist coatings on some glass types (such as self-cleaning glass or anti-reflective coatings) can be affected by polishing. A technician should assess this first.
How Much Does Glass Scratch Repair Cost?
Glass scratch repair is typically priced per pane or per area. Minor repairs to a small area of glass can cost from around a competitive ratea competitive rate. Larger areas or more severe scratches will cost more. In every case, this compares extremely favourably with glass replacement, which for a standard double-glazed unit can easily cost a competitive ratea significant sum, plus fitting costs.
When Should You Replace Rather Than Repair?
Replacement is necessary when the glass is cracked (not just scratched), when the double-glazed unit seal has failed (causing misting between panes), or when the scratch is too deep to be safely polished out. A specialist can advise you honestly on whether repair or replacement is the better option.
