Glass Replacement Services in Bristol
Most customers who contact us about a glass problem don't need a new window — they need a new sealed unit. The frame is usually in perfectly good condition, and replacing just the glass unit costs a fraction of a full window replacement.
We supply and fit all types of glass for Bristol homes. Getting the specification right matters — size, thickness, glass type, and whether toughened or safety glass is legally required. We handle all of that. Typical turnaround is around one week from measurement to fitting.

Why you almost never need a new window
The frame and the glass are separate components. When the sealed unit fails — misted, cracked, or broken — the frame itself is almost always fine. We remove the old unit and fit a new factory-made sealed unit in its place. The frame stays; only the glass changes.
The cost difference is significant:
| Option | Typical cost (+ VAT) |
|---|---|
| Sealed unit replacement (glass only) | From £165 |
| Full window replacement (frame + glass) | From £600 |
We'll always tell you which option is appropriate. If the frame is sound, there is no reason to replace it.
How quickly can it be done?
Glass units are manufactured to measure, so there's an order lead time — typically around one week from when we measure up. Once the unit arrives, fitting takes 30–60 minutes per pane. From your initial call to a clear, finished window, most jobs are completed within 7–10 days.
For broken glass where the window is open to the elements, we can sometimes arrange a boarded temporary solution while the unit is on order — call us to discuss.
Why has my double-glazed unit gone misty?
Misting between the panes means the hermetic seal has failed. Once the seal breaks, moisture gets between the panes and can't escape — causing the permanent cloudy or streaky appearance. The only solution is to replace the unit. The seal cannot be resealed, and the misting will not clear on its own.
Misting is most common in south-facing windows (more sun exposure means more thermal expansion) and in windows over 15–20 years old. It has no bearing on the frame condition — the frame is almost always reusable.
Specialist glass replacement

- Glass replacement in timber frames — broken panes, misted units, and traditional putty glazing in existing timber windows and doors
- Single glazing repair — single-pane and putty glazing replacement in older windows
- Aluminium frame glass replacement — misted or broken glass in aluminium windows and doors

Frequently Asked Questions
- It means the seal on your double-glazed unit has failed. Moisture has got between the panes and is condensing. The fix is to replace the glass unit — not the whole window. The frame itself is usually fine. From £165 + VAT per unit.
- No. In most cases you only need the sealed glass unit replaced. This is significantly cheaper than a full window replacement. If the frame is in good condition, a glass unit replacement is the right call.
- Toughened safety glass is a legal requirement for all door glass panels, and for window panes within 300mm of a door or within 800mm of floor level. We always quote toughened glass for these positions — no exceptions.
- We measure and order the glass unit first, which typically takes around one week. Fitting takes 30–60 minutes. Most glass replacements are completed within 7–10 days of your initial call.
