Frequently asked questions

Why has the glass in my Grantham window gone cloudy?
Cloudiness between the panes of a Grantham 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.
Do you work with facilities managers and contractors?
Absolutely - we regularly work for Grantham facilities managers, main contractors and property managers, with the documentation and reliability that commercial projects require.
