You can't safely repair a cracked glass hob-here's why DIY fixes fail, when replacement is your only option, and how to prevent cracks before they happen.
Cracked Glass Cooktop Repair: Fixes, Costs, and When to Replace
When your cracked glass cooktop, a smooth, flat surface on electric or induction stoves made of tempered glass-ceramic material. Also known as ceramic cooktop, it’s designed to handle high heat but can still shatter from impact, thermal stress, or poor installation. A small crack might seem harmless, but it’s a safety risk—moisture can seep in, electrical components can short, and the whole surface can suddenly break under pressure. This isn’t just a cosmetic issue. It’s a hazard that needs quick, smart action.
Most cracks happen for one of three reasons: dropping a heavy pot, sudden temperature changes (like pouring cold water on a hot surface), or a manufacturing flaw. If the crack is thin and doesn’t extend into the heating elements, you might be able to patch it temporarily with a high-heat ceramic adhesive. But most repairs like this are just that—temporary. The glass loses structural integrity, and the crack will spread. A professional might suggest replacing just the glass panel, which usually costs between £150 and £400 depending on your model. But if your cooktop is older than 8 years, or if the underlying heating elements or wiring are damaged, replacing the whole unit often makes more sense. You’ll save money in the long run by avoiding repeat repairs and improving energy efficiency.
Some people try DIY fixes with epoxy or glue from hardware stores. Don’t. Most adhesives aren’t rated for stove temperatures and can melt, smoke, or release toxic fumes. Even if it looks sealed, the surface won’t hold up under regular use. If you’re unsure, check your manual or look up your model number online. Many manufacturers offer replacement glass panels that snap right in. Brands like Bosch, Siemens, and Whirlpool have standardized parts, so finding the right one isn’t hard. Just make sure you turn off the power at the breaker before touching anything.
And if you’re thinking about upgrading, modern cooktops use tougher glass, better temperature sensors, and safer designs. A new unit might cost more upfront, but it’ll last longer, use less energy, and won’t leave you worrying about another crack next month. You’re not just fixing a stove—you’re making your kitchen safer.
