I've just bought a new flat (third floor in a 1910's tenement) which has pretty old and draughty single UPVC glazing at the front and old sash and case (is that right?) at the back. I'm looking at getting these replaced with double glazing - can anyone recommend a good company in or around Glasgow?
And what's the process, do I need to let loads of these guys in to my flat so they can measure up and give me quotes?
Any help would be much appreciated, cheers!
