Ceramic Hob Crack – What to Do When Your Cooktop Splits

First thing’s first – a cracked ceramic hob isn’t the end of the world, but you do need to act fast. Cracks can let water seep in, cause hot spots, or even shatter if you keep using the hob. The good news is most cracks are fixable without a full kitchen remodel.

Grab a flashlight and inspect the crack closely. Is it a thin hairline line or a big spider‑web pattern? Small hairline cracks usually mean a simple repair, while bigger, deep cracks often need a new surface. Also, check if the crack is spreading – if it’s growing after each use, replace is the safer bet.

DIY vs. Pro Repair – Which One Makes Sense?

If you’re handy and the crack is tiny, you can try a DIY kit. These kits come with a special epoxy resin that you spread over the crack, let it cure, and then sand smooth. It’s cheap (under £30) and works for minor damage. Just make sure the hob is completely cool and clean before you start.

For anything larger than a hairline crack, call a professional. A local Rugby technician knows how to remove the damaged glass panel, match the exact colour, and install a new one without breaking the surrounding glass. Professional glass hob repair costs in the UK typically range from £120 to £250, depending on size and brand. You’ll also pay a call‑out fee if you need same‑day service.

When to Replace the Whole Hob

Even the best repair can’t fix a hob that’s warped, has multiple cracks, or shows signs of overheating. If you notice:

• Uneven heating across the surface
• Cracks that run across the edge of the hob
• Repeated breakage after repairs

it’s probably time for a new cooktop. A replacement ceramic hob costs between £200 and £600, plus installation. If you’re already planning a kitchen refresh, swapping the whole unit often saves money in the long run.

Whatever you choose, always turn off the power at the mains before you start any work. Safety first, especially with electricity and heat involved.
