Make sense of visible building damage

A damp patch, a new crack or an unusual joint raises questions. ZMN supports you in Hildesheim, Hanover and the surrounding area with a structured visual inspection, indicative moisture measurements and photo documentation. The aim is a clear overview of findings and questions that still need clarification.

Service in detail

What we record on site

We distinguish visible findings from assumptions. This helps you discuss the next steps more precisely.

01

Visual inspection of affected areas

We look at accessible affected areas, their surroundings and visible changes. The timeline and any earlier repairs help with the initial assessment.

02

Indicative moisture measurements

Measurements can point to areas requiring attention. They are considered alongside materials, surroundings and visible conditions; on their own, they do not establish a cause.

03

Photo documentation

Overview and close-up photos record visible conditions. Clearly identifying affected areas makes later questions easier to address.

04

Findings & next steps

We summarise the agreed findings and identify open questions. If further investigation appears necessary, it is clearly described as requiring additional clarification.

Observation & documentation

Record visible signs clearly

What have you noticed on the building component? Your selection creates a documentation checklist for a site visit. It does not provide a diagnosis.

Select visible observations
Record observations over time

Note the first observation and visible changes. This organises your documentation without assessing the cause.

Dates are optional. Label comparison photographs with their actual capture date.

  • Keep original dated photographs and use a similar viewpoint for comparison images where possible.
  • Separate observations from assumptions. The sequence does not prove a particular cause.
Observation sequence · details form a documentation timeline

Select one or more observations. The general photographs already help prepare for a visit.

Schematic wall view · selected observations are highlighted
  • Take a room overview and a close-up of the area, only where access is safe.
  • Note the room, building component and when you first noticed it.

This preparation does not replace a professional expert report. A visual inspection cannot reliably establish hidden causes, structural capacity or hazardous substances. Avoid the area in an acute emergency and contact appropriate specialists. Do not open surfaces or disturb suspicious materials.

How it works

A clear route to an initial assessment

  1. Describe what you have observed

    Tell us where the damage is, when it appeared and how it has changed. Existing photos, plans or repair records help prepare the appointment.

  2. Inspect & document on site

    Accessible areas are inspected and documented within the agreed scope. Indicative measurements complement the visual inspection where appropriate.

  3. Discuss the findings

    You receive the agreed overview and guidance on open points. We distinguish findings, possible causes and necessary further investigations.

Questions about this service

No remote diagnosis or statement on structural safety. A formal expert report may require a suitably qualified surveyor.

Is this a report by a publicly appointed expert?
No. ZMN provides the agreed visual inspection, indicative moisture measurements and documentation. A report by a publicly appointed expert or a structural assessment is not included in this service.
Can the cause of damage always be identified?
No. Visible features and indicative measurements can provide clues. Concealed elements, material construction and other possible influences may require further investigation by appropriate specialists.
What should I have ready for the appointment?
Photos, a timeline, existing plans and information about earlier repairs are helpful. Arrange access to affected areas and tell ZMN about any requirements from the owner, property manager or insurer.
Will my insurer pay or accept the report?
Your insurer decides according to your policy and its requirements. Before commissioning work, clarify the documents required and whether costs will be covered.
