Why choose Commercial Glazing UK

Frequently asked questions

Why has the glass in my Greater London window gone cloudy?
Cloudiness between the panes of a Greater London unit means the seal has failed; replacing just the sealed unit clears it without changing the frame.
Can you replace units in any frame?
Yes - we replace sealed units in aluminium, timber, steel and uPVC frames where the frame itself is sound.
Is replacing the unit cheaper than a new window?
Much cheaper - you keep the existing frame and only renew the glass.
Which towns in Greater London do you cover for sealed unit replacement?
We provide sealed unit replacement across the whole of Greater London, including Croydon, Bromley, Ealing, Enfield, Barnet, Hackney and the wider Greater London.
