Many thanks,
I have submitted a claim now.
I have no faith in the NHBC at all, although I am not letting them away with it!
Could they try to use trim to fill the gap?
If they do, and I end up taking them to small claims (if I can keep the window replacement cost below £10,000), would I have to get the work done first, or would the court accept quotes?
Many thanks - only when we push back will anything change!
