Things to decide before you order
Beads inside or out
Externally beaded windows can have the glass removed from outside. We fit security tape or clips so that route is closed.
Which windows first
Start with windows that can be reached without a ladder and are out of sight from the street. We can schedule the rest for later.
Rules that apply in England
Windows needed for escape
Approved Document B expects many habitable rooms in houses, particularly upstairs, to have an escape window with a clear opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. Changing the glass does not alter that, but locks, secondary glazing and film must not stop the window opening. Laminated glass is hard to break through, so escape always relies on the window opening.
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

No. If your frames are in good condition, we replace just the glass with laminated units made to fit them.
