We had an extension built in the last couple of months and they finished a few weeks ago, as part of this we had two large bi-fold doors fitted. We are still having the room painted and are not using it yet so we hadn't bothered to clean the glass in the doors just yet. Over the weekend though I noticed that some of what we though was just dust is actually scratches and on closer inspection most of the panes have some quite deep scratches round the edges which look like they were done when they were fitted. Our builder never did a walk around or end of build inspection with us and we've not signed anything to say we are happy with the finished work either. The thing is its been a couple of weeks since he finished, we don't owe him any more money and so I think the chances of him agreeing to come and replace the scratched glass is non-existent. We did however spend £8k on bi-fold doors and are not that happy that they are scratched to buggery. I'm going to tell him about the scratches but if he doesn't want to know what are my options for getting this sorted, would a small claims court thing be something we could consider?
