Common door glass problems we fix

Smashed or cracked door glass

Impact damage — accident, break-in attempt, or stray ball — needs dealing with quickly. A broken door panel is a security risk and a draught issue. We prioritise making the door safe and ordering the correct replacement unit. If the door is compromised while the glass is on order, we can advise on temporary boarding.

Misted or blown sealed units

A permanent cloudy or streaky appearance means the sealed unit's hermetic seal has failed. Moisture between the panes won't clear on its own, and the proper fix is usually replacing the sealed glass unit, not resealing the old one. The door frame is unaffected; we replace the glass panel only.

Decorative or obscure glass panels

Many uPVC and composite doors have decorative lead-effect, frosted, or obscure / privacy glass panels. These can be matched and replaced when damaged. Lead-effect units are factory-made as a complete sealed unit — they're replaced whole, not repaired in situ. Composite door glass and cassettes: see composite door repair.

Door glass problems and what's needed

Here's what the common door glass problems usually mean and the best next step. Toughened safety glass is what door panels normally need, and we quote it as standard. These are general guides — send us a photo and we'll confirm the right unit before ordering.

How we replace door glass

The process is the same whether the glass is misted, smashed, or decorative:

• Measure up: We visit to measure the existing panel precisely. For many standard door panels we can give an initial guide from photos, but a site measure ensures the unit is ordered correctly.
• Order the unit: Glass panels are manufactured to the exact size. Lead time is usually around 5 working days from your deposit (allow up to 10 in busy periods); decorative or non-standard units may take a little longer.
• Fit and finish: We remove the old panel, fit the new toughened unit, refit the beading, and check the door operation. Most fitting appointments take 30–60 minutes.

The door frame stays — you're not paying for a new door, just new glass. Glass units usually take around 5 working days from your deposit — allow up to 10 in busy periods.

What does it cost?

Door glass panels require toughened safety glass as standard, which costs slightly more than standard window glass. Adding lead or Georgian bars can add about £15–£50 + VAT (£18–£60 inc VAT) to a unit, depending on its size.

We agree the price before ordering anything. A full door replacement is far more expensive — £1,300 + VAT for a white uPVC back door, from £1,500 + VAT for a uPVC front door — so replacing the glass only is usually far cheaper where the frame and door are sound.

Do I need a new door?

Usually not — not if the door frame and slab are still sound. If the door frame and slab are sound, replacing the glass panel gives you a clear, sealed, secure result at a fraction of the cost of a new door. There's no reason to replace the whole thing when only the glass has failed.

If you're already considering a new door, we can advise honestly on whether repair still makes better sense.

Frequently asked questions

• How much does door glass cost to replace?

  £295–£325 + VAT (£354–£390 inc VAT) for front, back or French door glass, toughened as standard. Adding lead or Georgian bars can add about £15–£50 + VAT (£18–£60 inc VAT) to a unit, depending on its size.

• Why is door glass more expensive than window glass?

  Door panels need toughened safety glass, which we quote as standard. Decorative and lead-effect units are also made as a complete sealed unit rather than assembled on site, which adds a manufacturing step.

• Can you match my existing decorative glass?

  Often, yes. Lead-effect and patterned units can usually be matched. Send a photo of the panel and we will tell you what is achievable before anything is ordered.

• Do I need a whole new door?

  Not if the door slab and frame are sound. A new door is £1,300 + VAT for a white uPVC back door, or from £1,500 + VAT for a uPVC front door, so replacing the glass alone is far cheaper where the door itself is fine.
