What is double glazed glass replacement?

Double glazed glass replacement means removing a broken, cracked or smashed sealed glass unit and fitting a new made-to-measure unit in the existing frame. You keep your uPVC or aluminium window or door and replace only the glass.

At Window Fixers it costs from £220 per unit, supply and fit, including VAT. We measure, have the unit made in 3–5 working days and aim to fit it within a week of your order.

Common problems

When your double glazing needs new glass.

A damaged pane rarely means a new window. Send us a photo and we’ll confirm what needs replacing before you book.

A cracked pane

A crack takes away much of the glass’s strength, so the pane can give way suddenly.

Smashed or shattered glass

Impact damage or a break-in has left the unit broken and the opening exposed.

Cracked on its own

Thermal stress, frame movement or tiny edge damage can crack glass without anything hitting it.

Broken door glass

Damaged glass in uPVC, French, sliding patio or bifold doors, replaced with safety glass.

Draughts and damp

A crack breaks the seal, letting cold air and moisture into the unit.

A home that isn’t secure

Broken glass weakens security. We prioritise smashed and insecure units.

We replace glass in uPVC and aluminium windows and doors. We don’t replace glass in timber windows or doors, single or secondary glazing, Velux windows or old aluminium sliding doors, and we don’t repair damaged frames.

Prices

How much does double glazed glass replacement cost?

Fixed prices per sealed unit for supply and fitting, made to measure. VAT included and no call-out charge.

How it works

Fixed in three simple steps.

Two visits: one to measure, one to fit. We aim to replace every unit within a week of your order.

Send a photo or video

WhatsApp or email a photo of the broken glass. We reply with a fixed price the same day. No sales visits, no pressure.

We measure and make it

Your engineer measures the frame to the millimetre and checks glass thickness, tint and safety needs. The unit is made to order in Pilkington glass with warm-edge spacer bars, typically in 3–5 working days.

We fit and clear up

We return to swap the glass, usually in one to three hours. We make a watertight seal, clean the glass and take the old unit away for responsible disposal.

Made to match

Each unit matches your glass type, thickness, tint and pattern, so the new pane doesn’t stand out.

From £220 per unit, supply and fit. VAT included, no call-out charge and no parking fees.

10-year guarantee

Every new sealed unit is guaranteed for 10 years against misting and seal failure.

FAQ

Glass replacement questions, answered.

Can’t see yours? Send us a message and we’ll reply in minutes.

How much does it cost to replace a double glazed unit?

Double glazed glass replacement starts from £220 per unit, supply and fit, including VAT. The final price depends on the pane size and glass type: obscure glass from £239, toughened from £264, door glass from £299 and bifold door glass from £599. There’s no call-out charge, and three or more units in one visit get 20% off.

How long does it take to replace double glazed glass?

We aim to replace every unit within a week of order confirmation. After we measure up, the unit is made in 3–5 working days, and fitting usually takes one to three hours. Special orders may take longer.

Can I replace the glass in my existing window frames?

Yes, in most cases. We fit a new sealed unit in your existing uPVC or aluminium frame. If the frame itself is damaged or worn, the whole window or door may need replacing.

Can I replace just one pane of a sealed unit?

No. Both panes are bonded into one sealed unit, so we replace the complete unit. This keeps the insulation and seal intact, which is what stops future misting.

Why did my double glazing crack on its own?

Common causes are thermal stress, when part of the pane heats or cools faster than the rest, movement in the frame, or tiny edge damage from manufacture. Rarely, toughened glass breaks spontaneously. We identify the likely cause and fit a correctly specified replacement.

Do you offer emergency or same-day glass replacement?

We prioritise smashed and insecure units and quote the same day from a photo. Standard clear units can often be turned round quickly; toughened, laminated, obscure and door glass is made to measure and takes a few working days. We’ll advise how to make the opening safe meanwhile.

What should I do if my double glazed window has just smashed?

Keep children and pets away and don’t pull out large shards by hand. If it’s safe, tape or cover the opening. Take a clear photo for your quote and any insurance claim, and send it to us. We remove and dispose of the broken unit when we fit the new one.

Is it safe to leave a cracked double glazed window?

It’s best not to. A cracked pane can give way suddenly, and toughened glass may shatter completely. The crack also breaks the seal, letting in draughts and moisture, and weakens security.

What’s the difference between toughened and standard glass?

Toughened glass is heat-treated to be several times stronger than standard annealed glass and breaks into small blunt granules, not sharp shards. UK rules require toughened or laminated safety glass in doors and low-level windows, so we fit it there as standard.

Does your guarantee cover broken glass?

Our 10-year guarantee covers manufacturing faults such as seal failure, condensation and misting. Like any glazing guarantee, it doesn’t cover accidental breakage or break-ins.

How much does window glass replacement cost compared with a new window?

Replacing only the sealed glass unit starts from £220, against several hundred pounds or more for a complete new window and frame. Because the frame stays in place there is no making good, so a glass-only replacement is typically up to 70% cheaper and done in one short visit once the unit is made.

Can you replace the glass in aluminium windows and doors?

Yes. We fit new made-to-measure sealed units into aluminium as well as uPVC frames, in windows, doors and patio doors, matching the glass type, spacer and thickness to your frame.

Are you local glaziers near me?

Our glaziers are based in Ilford, not a national call centre, and cover every London borough and much of Kent, including Bromley, Bexley, Dartford, Sevenoaks and Maidstone. Send your postcode with a photo of the broken glass and we’ll confirm we cover you and give you a fixed price.

What is sealed unit replacement?

A sealed unit is the two panes of glass in a double glazed window or door, bonded together around a spacer bar and filled with argon. When one pane is cracked or smashed, or the seal fails, we replace the whole sealed unit with a new A-rated one made to measure, from £220 supply and fit. The frame stays in place.

Can you replace broken glass in a uPVC, French or bifold door?

Yes. Door glass is replaced with toughened or laminated safety glass, as UK rules require. uPVC and French door glass starts from £299, bifold door glass from £599 and sliding patio door glass from £899 per unit, supply and fit, including VAT.
