Frequently asked questions

Why has the glass in my Dartford window gone cloudy?
Cloudiness between the panes of a Dartford 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 provide a written quotation for Dartford work?
Yes - after a free site survey we provide a clear, itemised and fixed written quotation for your Dartford project, so you know exactly what is included before committing.
