Why choose Commercial Glazing UK

Frequently asked questions

Why has the glass in my County Londonderry window gone cloudy?
Cloudiness between the panes of a County Londonderry 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 County Londonderry do you cover for sealed unit replacement?
We provide sealed unit replacement across the whole of County Londonderry, including Londonderry, Limavady, Magherafelt, Coleraine and the wider County Londonderry.
