What Happens If My Neighbour's Building Work Causes Damage?

Building work next door can sometimes cause cracking or other damage to neighbouring property. If this happens, the first step is to record the concern and establish whether the damage is connected to the works.

What should I do if I notice damage?

Record the condition as soon as reasonably possible.

Take clear photographs and note when you first noticed the problem.

If the damage is changing, keep a dated record.

Where there is an immediate safety concern, seek appropriate urgent professional assistance.

Why is a Schedule of Condition useful?

A Schedule of Condition records relevant parts of a neighbouring property before construction begins.

It may include photographs, notes on existing cracks, decorative finishes and other visible defects.

The report provides useful evidence if questions arise later about whether a defect existed before the works.

However, it doesn't automatically establish who caused any subsequent damage.

What happens if there's a Party Wall Award?

Where the matter is within the Act and an Award has been made, the surveyor or surveyors may be able to determine certain disputes arising from the notifiable works, including relevant damage and making-good matters.

The exact position depends on the Award, the works and the surveyors' statutory jurisdiction.

Assessment of the relevant facts

A change in condition does not automatically establish its cause.

Can I request compensation?

The Act provides for compensation in certain circumstances involving loss or damage caused by works carried out under it.

Depending on the circumstances, the appropriate remedy may involve making good the damage or resolving a monetary claim.

Not every allegation of damage falls within the Party Wall surveyors' jurisdiction. Some disputes may need separate legal or expert advice.

What should you do next?

If you're concerned about damage associated with your neighbour's building work, send us the relevant correspondence and photographs so we can consider whether Party Wall advice is appropriate.
