I just wanted to add my bit for Steve and his team who did a sterling job on my 100-year old windows earlier this year (I've written about this elsewhere on the forum). Having had some building work done subsequently, a few of the windows had got knocked and panes cracked in the process. Steve's guys came over and repaired the lot (5 of them in all) in just a day and a half. I was dreading the dust and mess to be honest as the house is now (finally) nearly finished and Steve said the frames had to come out to get the glazing in. However his boys did a ridiculously neat job and were painstaking in the way they cleared up at the end of the day. Amazing service and didn't cost the earth. In my entire ground-floor-to-roof-refurb I can honestly say the windows were the least stressful element of the whole project.
