The best aspect for me was the ease of doing business with you and getting a quote via e-mail without going through the notorious double glazing sales pitch at your home experience. The price quoted seemed competitive so I accepted and the delivery timescales were short too, so all good so far. During fitting, a surveying error was also corrected without quibble, so again good. What let it down was one or two too many scratches dents etc on the window frames and some rushing by the fitters at the end. I don't know if it's the factory or the fitters, but you expect something that's new to be perfect and not have scrathes and dents. The cementing round the back door is already crumbling away and we've also noticed they forgot to seal underneath the front door step - we can still see the foam. The factory also delivered one of the windows with only the horizontal leading for the leaded lights and then "dropped" the replacement, so overall I don't get a good feeling about their quality control and general care of the products. And because the fitters had to have extra visits, they seemed to be under progressive time pressure to move on to their next job rather than want to make sure you were happy with the current job. So what started out very positively was slightly spoilt by the little things towards the end. I have photos but can't attached to this feedback. On the product itself, I also don't find the "natural weathering" look of the leaded lights a good thing.
