Construction works and adjoining properties: protect your property

A contradictory property inspection before the works start protects both neighbours and the client against later discussions.

Construction works and adjoining properties: protect your property - plaatsbeschrijving Antwerpen

Building or thoroughly renovating entails risks - not only for your own property, but also for your neighbours. A contradictory property inspection before, during, and after the works protects everyone against subsequent discussions about damage.

The problem in a nutshell

During major construction or renovation projects, vibrations, settlements, or construction activity can cause damage to adjacent properties: cracks in walls, damaged facades, problems with roofs or foundations. Without prior assessment, it is virtually impossible afterwards to demonstrate what was caused by the works and what was already present.

The solution: contradictory property inspection

A contradictory property inspection is an assessment drawn up in the presence of all involved parties - the client and the neighbours - by an independent expert. The report has probative value in court.

What we record

* Existing cracks, moisture stains, and finishing details * High-resolution photos of facades, roofs, and sensitive elements * Description of existing repairs and their quality * A clear report that is legally sound

When should this happen?

Ideally in three phases:

1. **Before the works** - the basic assessment. This is the crucial moment. 2. **Interim** - during major, risky interventions (demolition, foundation, piling). 3. **After the works** - to objectively determine any new damage.

Who is this relevant for?

For the client You protect yourself against unjustified damage claims. Neighbours cannot claim that damage was caused by your works if that damage already existed. Your liability insurance works more smoothly and cheaply.

For the neighbours You are sure that any new damage is demonstrable. No he-said-she-said with the client or their contractor - the report is your proof.

For the contractor A pre-prepared report also protects your reputation and liability. Unjustified claims are quickly refuted.

What it brings you in practice

* **Legal certainty for all parties** - the report is signed by everyone * **Faster dispute resolution** - in case of dispute, the evidence is immediately available * **Lower insurance costs** - insurers appreciate objective documentation * **Preservation of a good neighbourly relationship** - independence prevents personal conflicts

Practical advice

Do not wait until after the first complaint. At that point, it is often already too late in terms of evidence. Plan a property inspection as soon as you receive your building permit and inform your neighbours in good time. A small investment beforehand often saves you thousands of euros and years of procedures afterwards.
