You need to get a surveyor out to look at it and give you a report. This will state if anything is wrong with it. If there is something wrong your neighbour should repair it.
If there is nothing wrong - clearly the matter ends and there is nothing you can do.
Once you know what is wrong then you can get a number of quotes to put it right and that then becomes your loss
You need to write and set out your losses and request either he fixes it or you will sue for the cost within 14 days or say you will go to Court within 14 days. You should make sure you send this recorded delivery and keep a copy.
If they do not you then you can issue proceedings in the County Court. You can either do this online at: www.moneyclaim.gov.uk or by completing form N1 http://hmctsformfinder.justice.gov.uk/courtfinder/forms/n001-eng.pdf and take it to your local County Court.
The Court will then issue a claim which a copy will be sent to the Defendant who will have a limited time to defend it, if not you can enter Judgment and enforce.
If the matter is defended it will be set down for a trial. If the claim is for £10,000 or less it will be a small claim and you will not need representation.
Can I clarify anything for you about this today please?
