Assuming there are no hidden matters you are not disclosing, I think you have been more than patient for a resolution.Have you spoken to the NHBC. The builder is NHBC registered, therefore you have a route of complaint there. Alternatively - you may wish to try this first to prove you have given the builder every opportunity to remedy the situation - the builder's Head Office is in Sussex. Have you contacted them there? Quote to them their own words on their website - "We believe in providing the very best in planning, innovative design, construction and service..." Tell them they have failed you and your neighbours badly in this respect.There should be no need in today's society to go down a route of legal action. You have the law on your side if your claim is valid - but the company knows this and will not want the adverse press. Which is your third course of action. Tell the builder that if a resolution is not agreed within seven days, you will be calling in the media.Light the blue touch paper; step back...Keep us informed as to progress.
