How to Replace Cracked Glass in a Stove

Article Summary

Most stove doors hold the glass in place with retaining clips or clasps, which can be released so the damaged glass can be removed and replaced.

The seal between the glass and the door can become worn or frayed over time, so it is worth replacing the rope at the same time if needed.

The new stove glass needs a little movement against the rope seal, so the clips should be tightened carefully to avoid cracking the replacement glass.

Stove glass is made to cope with very high temperatures, but it can still become cracked or damaged through impact, a slammed door or pressure from the retaining clips. If the glass has cracked, it will need replacing. On many stoves this is a fairly straightforward job, although the exact way the glass is held in place varies between models.

Let the Stove Cool Completely

Never attempt to remove the glass while the stove is hot. Let the stove and door cool completely before starting. Broken stove glass can have sharp edges, so wear suitable gloves and take care when removing any loose pieces. If the stove door can be removed easily, taking it off and laying it flat can make the job much easier.

Remove the Old Stove Glass

Most stove doors hold the glass in place with small retaining clips or brackets. Carefully loosen these while supporting the glass so broken sections don’t fall out unexpectedly. If the screws or clips have become stiff over time, work them loose carefully rather than forcing them. Once the fixings are released, remove the old glass and clear away any remaining pieces.

Check the Glass Seal

With the old glass removed, have a look at the rope or seal between the glass and the stove door. If it has become frayed, flattened or damaged, this is a good time to replace it rather than fitting new glass onto a worn seal. We sell replacement stove door rope in several sizes for compatible stoves.

Fit the Replacement Glass

Make sure you have the correct replacement glass for your stove before fitting it. Position the new glass onto the seal and refit the retaining clips or brackets. Take your time here. The clips need to hold the glass securely, but they shouldn’t be overtightened. Stove glass needs a small amount of movement as the stove heats and cools, and overtightening the retaining clips can put unnecessary pressure on it.

Check the Door Before Using the Stove

Once the new glass is fitted, check that:

The glass sits evenly against the seal
The retaining clips are secure but not overtightened
The rope or glass seal is in good condition
The stove door closes properly

If anything doesn’t look right, check the instructions for your particular stove before using it.

Why Does Stove Glass Crack?

Heat on its own shouldn’t normally cause suitable stove glass to crack. Damage is more commonly caused by something hitting the glass, closing the door against a log or putting too much pressure on the glass when the retaining clips are fitted. If you’re replacing the glass, it’s worth checking for an obvious cause so the same thing doesn’t happen again.

Where Can I Buy Replacement Stove Glass?

We sell replacement stove glass and spares for a selection of the stoves we supply. Most stove manufacturers also have dedicated replacement glass available for customers to buy directly, so if we don’t stock the glass for your particular model, it’s worth checking with the manufacturer. If you’re unsure which glass you need, check the stove make and model before ordering.
If the stove came from us and you’re struggling to identify it, send us a photograph and we’ll help where we can.
