Frequently asked questions

Why has the glass in my Lancaster window gone cloudy?
Cloudiness between the panes of a Lancaster 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.
How do I get a quote for sealed unit replacement in Lancaster?
