Windscreen Chip Repair: Why Speed Matters
A stone chip looks harmless, but a windscreen is under constant stress from temperature swings, vibration and the flex of the body over bumps. That tiny bit of damage is a weak point, and given time it almost always spreads into a crack. Repair it early and it's a quick, cheap job. Leave it and you're often looking at a full windscreen replacement instead.
Stops It Spreading
A chip repair fills and seals the damage so it can't run into a long crack, the single biggest reason to get it seen quickly rather than leaving it.
Cheaper Than Replacing
Repairing a chip costs a fraction of a new windscreen, and if your insurance covers glass, a repair often means little or no excess to pay at all.
Clearer View
A good repair restores strength and greatly improves clarity, so a chip that was catching the light and distracting you is far less noticeable afterwards.
Windscreen Chip Repair vs Full Replacement
It comes down to size, position and how fresh it is
As a general rule, a chip roughly the size of a £1 coin or smaller can usually be repaired, as long as it isn't sitting right in the driver's line of sight, isn't too close to the edge of the glass, and hasn't already run into a long crack. Fresh, clean chips repair best, dirt and moisture getting into the damage over weeks and months make a lasting repair harder.
Damage that's larger than a coin, a crack longer than around 75mm, a chip in the driver's critical vision area, or damage right at the edge of the screen where the glass is weakest, will normally need a full windscreen replacement rather than a repair. If that's the case, we'll tell you plainly and arrange the replacement for you rather than attempting a repair that won't last.

Windscreen Chip Repair: What Ignoring It Risks
Putting off a windscreen chip repair is one of those small jobs that quietly turns into a big one. A chip that could have been sealed in minutes becomes a crack across the glass, and the options, and the costs, narrow fast. Here's what's genuinely at stake.

Windscreen Chip Repair: The MOT Rules
⚠ A chip in the driver's line of sight is an MOT fail
The MOT rules on windscreen damage are stricter than most people expect, and they're all about where the damage is. Directly in front of the driver, in the swept area of the wiper roughly 290mm wide known as Zone A, any damage larger than 10mm, about the size of a 5p coin, is an automatic MOT fail. That's why a chip in your line of sight matters so much more than one over in the corner.
Across the rest of the wiper-swept area, the limit is more generous, damage up to around 40mm is usually allowed before it fails. But even damage that technically passes can still spread, so it's always worth repairing rather than gambling on it holding until next year.
Worth knowing: if you spot a chip before your test, a quick repair beforehand can turn a certain fail into a clean pass. Book it in alongside your MOT and we'll sort the chip first.
Windscreen Chip Repair: How It Works
A windscreen chip repair is a genuinely quick job. We clean the damage, draw out any trapped air and moisture, then inject a clear resin into the chip under pressure and cure it hard so it bonds with the glass. Once it's set and polished, the chip is sealed, the screen is stronger, and the damage is far less visible than before. Most repairs are done while you wait.


If the chip is beyond repair we'll arrange a full windscreen replacement rather than push a fix that won't hold. And while your car's in, it's the perfect moment for a quick free car health check so you know if anything else needs attention, or to combine the visit with your MOT and save a second trip.
Windscreen Chip Repair: Feedback
Caught a chip early and they repaired it in about twenty minutes while I waited. Barely see it now and it saved me a whole new screen.
Google Review
Chip was right in front of me so it would have failed the MOT. They sorted it first, then did the test. Honest and quick, can't fault them.
Google Review
Told me straight that mine was too big to repair and arranged a replacement instead of wasting my money. That kind of honesty keeps me coming back.

Windscreen Chip Repair: FAQ
Real, in-depth answers to what people actually ask before booking a windscreen chip repair.
As a rough guide, a chip around the size of a £1 coin or smaller can usually be repaired, provided it isn't in the driver's direct line of sight, isn't right at the edge of the glass, and hasn't already run into a long crack. Fresh, clean chips give the best results.
Bigger damage, long cracks, or chips in your critical vision area normally need a full windscreen replacement. Send us a photo on WhatsApp or bring the car in and we'll give you an honest answer either way.
It depends where it is. In Zone A, the roughly 290mm strip directly in front of the driver, any damage larger than 10mm is an automatic fail. Across the rest of the wiper-swept area the limit is around 40mm before it fails.
So a small chip in your line of sight is far more serious for the MOT than a larger one over in the corner. If yours is borderline, repairing it before the test is the safest bet, and we can do both in one visit alongside your MOT.
A single chip repair is quick, typically well under an hour and often around twenty to thirty minutes. Most people wait while it's done rather than leaving the car with us.
If there are several chips, or the damage turns out to need a replacement instead, it takes a little longer, we'll tell you exactly what's involved and how long before we start.
Many comprehensive policies include windscreen and glass cover, and because a chip repair is so much cheaper than a replacement, some insurers cover it with a reduced excess or none at all, and it often doesn't affect your no-claims. It's always worth checking your policy before you assume it'll cost you.
Cover varies from insurer to insurer, so we'd suggest a quick look at your documents or a call to your provider. Whatever you find, we're happy to talk you through your options.
A small chip away from your line of sight is usually fine to drive with in the short term, but it shouldn't be left. The windscreen is a structural part of the car and helps the roof hold its shape in a crash, so damage weakens it. A chip can also spread into a crack with no warning.
If the chip is in your direct line of sight, or it's already turning into a crack, treat it as urgent, both for safety and because it'll fail an MOT. Get it seen quickly and, where possible, we'll repair it the same day.
A good repair greatly improves clarity, but it's honest to say most repairs leave a faint mark where the damage was, it's a repair, not a brand-new pane of glass. The main jobs of the repair are to restore strength and stop the chip spreading, and both of those it does well.
In practice, a repaired chip that used to catch the light and distract you becomes far less noticeable. If perfect invisibility matters more than cost, a replacement is the only way to achieve that, and we'll be upfront about the trade-off.
A chip repair is far cheaper than a full windscreen replacement, and the exact price depends on how many chips there are and their condition. If your insurance covers glass, a repair often costs you little or nothing once any excess is taken into account. Give us a call and we'll give you a straight price.
For a full replacement, where that's needed, you can also spread the cost with our Payment Assist option over 3, 4 or 6 monthly payments at 0% interest, with no hard credit check for bills up to £1,000.
Short cracks, generally under around 75mm and away from the edge and driver's eyeline, can sometimes still be repaired, but once a crack gets longer or reaches the edge of the glass, a full replacement is the safe and lasting answer. This is exactly why catching a chip early matters so much.
Bring it in and we'll assess it honestly. If it can be repaired we'll do it, and if it can't, we'll arrange the replacement rather than attempt a fix that won't hold.
Yes, and it's the sensible way to do it. Booking your chip repair alongside your MOT or service saves a second trip, and getting the chip sorted first means it won't be the thing that fails your test.
Just tell us what you'd like doing when you book and we'll fit it into the same visit. While the car's in, we can also run a quick free health check so you know where everything else stands.
As soon as you can. A chip is at its most repairable when it's fresh and clean, before dirt and moisture work their way in and before a change in temperature sends it running into a crack. Cold snaps, hot sun and even a blast of the heater can be enough to make a stable chip spread.
It's a quick, low-cost job caught early and a much bigger one left late, so the moment you notice a chip, get it booked in. Pop a bit of clear tape over it in the meantime to keep dirt out until we can see it.
