Very good. We have always been treated really well when we have called at the showrooms and the fitters have been first class, very helpful and friendly and, above all, they do a great job. When some of our our windows, which were fitted approx 12 months ago, needed some fine tuning, Terry Cann was brilliant at sorting it all out! The only slightly negative comment is that a couple of the people in the office are very slow at returning calls - surely you could have a system whereby if a phoneback is more than, say, 4 hours old someone just phones to say that the individual is still busy but will contact you ...............
