Frequently asked questions

Why has the glass in my Bishop's Stortford window gone cloudy?
Cloudiness between the panes of a Bishop's Stortford 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.
Are you insured for commercial glazing in Bishop's Stortford?
Yes - we carry full public liability insurance for commercial glazing work in Bishop's Stortford and across Hertfordshire, and can provide details on request.
