Replace cracked, broken or misted double-glazed units in bifold doors. We supply and fit replacement glass for uPVC, aluminium and timber frames across London, Essex, Hertfordshire and Kent.

Condensation trapped between the panes usually means the sealed unit has failed.
Replace damaged glass safely and restore the door to a clean, usable condition.
A new sealed unit can improve clarity and help prevent the problem from getting worse.
We replace blown double-glazed units in bifold doors and work with common uPVC, aluminium and timber frames. The existing frame is checked before the glass is ordered.

Show us the damaged or misted unit and tell us where the property is located.
We check the frame, measurements and glass specification needed for the replacement.
Old glass is removed safely and the replacement sealed unit is installed professionally.
If the frame, hinges and running gear are in good condition, replacing the glass unit may be all that is needed. We will explain what needs replacing before the work starts.
The aim is simple: remove the damaged unit, fit the correct replacement and leave the door looking and working properly.

Joanne Friswell2025-08-20Trustindex verifies that the original source of the review is Google. I cannot emphasise enough how great was the customer service. My door is now as good as new. Before, I did not appreciate the mechanics of the door, but I have been educated. If your door needs fixing, I’d recommend this company.
