24/7 Emergency Cover
Cracked, shattered, misted or damaged glass doesn’t necessarily mean replacing the entire window or door. In many cases, the affected pane or sealed glass unit can be replaced while retaining the existing frame, providing a straightforward way to restore the appearance, safety and performance of your glazing.
Window Doctor provides professional glass replacements through our nationwide network of local branches, working with windows, doors and other glazed installations in residential and commercial properties.
Our experienced glaziers replace a wide range of single, double and triple glazing, from standard replacement panes and failed double glazed units to specialist toughened, laminated, fire-resistant and privacy glass. We’ll assess the existing installation and identify the appropriate type and specification of replacement glass for the application.
Available 24/7 for any emergency, call us today on 0800 043 0095 for a free quote and have your glass replaced by the best!

Common Reasons To Replace Your Glass:
Window and door glass can become damaged or require replacement for many different reasons. Some problems are immediately obvious, while others develop gradually over time.
Common reasons for replacing glass include:
- Cracked glass – impacts, accidental damage or stresses within the installation can cause cracks to develop.
- Shattered or smashed glass – severely damaged glazing will normally require complete replacement.
- Misted double glazing – condensation between the panes can indicate failure of the sealed glass unit.
- Cloudy or steamed-up glass – failed sealed units can gradually become increasingly difficult to see through.
- Burglary or break-in damage – attempted or successful forced entry can leave windows and doors with broken glazing.
- Impact damage – stones thrown by lawnmowers and other accidental impacts are a common cause of cracked or shattered glass.
- Scratched, stained or permanently marked glass – significant surface damage can affect the appearance of otherwise serviceable windows and doors.
- Failed double or triple glazed units – sealed glazing units can deteriorate independently of the surrounding frame.
- Unsuitable existing glass – some locations may require a different type of safety or specialist glazing.
- Privacy requirements – obscured or privacy glass can be installed where additional screening is required.
- General deterioration – older glazing may eventually require replacement while the surrounding window or door remains perfectly serviceable.
Where possible, Window Doctor’s approach is to replace only the component that actually needs replacing. If the frame and surrounding installation remain in good condition, there is often no reason to replace the complete window or door simply because the glass has failed.

We can also replace traditional glazing, privacy glass, shop front glazing and other specialist glass depending on the existing installation and its requirements. Where double glazing has become cloudy or developed condensation specifically between the panes, our misty glass replacement service provides more information about replacing failed sealed units.

Frequently Asked Questions - FAQs
Can you replace the glass without replacing the whole window?
Yes, in many cases. If the window frame remains in good condition, the individual pane or sealed glass unit can usually be replaced while retaining the existing frame. The same principle applies to many glazed doors.
What types of glass can Window Doctor replace?
Window Doctor replaces a wide variety of glazing, including single, double and triple glazing, toughened glass, laminated glass, fire-resistant glass, privacy glass and traditional glazing. The appropriate replacement depends on the particular installation and where the glass is being used.
Can you replace misted double glazing?
Yes. If condensation or misting has developed between the panes of a double glazed unit, the affected sealed unit can often be replaced without changing the complete window frame.
Can you replace smashed or cracked glass?
Yes. Window Doctor replaces cracked, shattered and otherwise damaged glass in suitable windows, doors and other glazed installations. Where broken glazing leaves a property exposed, emergency boarding may also be available before replacement glass is installed.
Do you provide commercial glass replacements?
Yes. Through our nationwide network of local branches, Window Doctor provides glass replacement services for both residential and commercial properties, including suitable windows, doors, shop fronts and other glazed installations.
