The Criminal Damage Act states:
"A person who without lawful excuse destroys or damages any property belonging to another intending to destroy or damage any such property or being reckless as to whether any such property would be destroyed or damaged shall be guilty of an offence".
If you believe that someone has contravened that Act, contact the police.
If you believe that someone carrying out next door has caused damage to your property, your first step though would normally be to advise that person (or company) in order that might be given the chance to remedy the matter (or to ask their insurers to do so).
