Why now
Because prevention beats repair.
A crack in the perimeter joint costs you a joint today. In three years it costs you the build-up beneath it. The difference between the two is an investigation.
How we work
How a commission runs with us
From the first enquiry to completion – transparent, to fixed dates and with no surprises in the costs.
- 01
Enquiry and first conversation
You describe the problem – online through the enquiry form or by telephone. Within 48 hours on working days we come back to you with a first assessment.
- 02
Investigation plan and quotation
We determine which methods will actually answer the question and state scope, date and cost bindingly – without investigations nobody needs.
- 03
Investigation on site
Measurement and sampling at the building, arranged around your operations. We organise the access and safety equipment as well.
- 04
Evaluation and report
You receive a report that keeps findings and assessment cleanly apart, supports every statement with measured values and ends in a clear recommendation.
- 05
Support during the works
On request we support tendering, award and site supervision – so that the recommended measure is actually carried out as recommended.
Your contact
Jason Davis Kunz
Owner and expert in building diagnostics
From the first enquiry to the finished report you deal with the same person – the one who comes to the site and takes the measurements himself.
Independent here means: we do not carry out what we recommend. So we tell you not only what needs doing, but also what you can save yourself.
Common questions
What clients want to know before they call
If your question is not here, call us – asking costs nothing.
What does an investigation cost?
That depends on which methods will actually answer your question. So we state scope, date and cost bindingly in the quotation, before anything is measured – not as a surprise on the invoice. The first assessment following your enquiry is free of charge.
How quickly do you respond?
Within 48 hours on working days you receive a first technical assessment. If the matter is urgent, say so on the form or call us – then it is faster.
Will one of your reports stand up to scrutiny from the other side?
That is what it is built for. Findings and assessment are kept apart, every statement is supported by measured values, every measuring point is located and photographed. Anyone wishing to disagree has to disprove the measurement, not the opinion.
Do you also carry out repairs on what you have assessed yourself?
In sealing and repair we do the work ourselves. Where we act as an expert, we keep that separate: an assessment that ends in a commission for the assessor is not an assessment. Which role we hold is settled before the commission begins.
Do I need to be present at the site visit?
At the start it helps if someone who knows the building is there – the rest works without you. Access and time slots are agreed in advance.
What should I prepare?
Whatever exists helps: as-built drawings, earlier reports, photographs from the time the damage appeared. If none of it exists, that is no obstacle – then we start with the survey.
Will anything be cut open?
As little as possible. We measure non-destructively first and open up only where an opening genuinely tells us something. Where we do open up, we say so beforehand – and we close it again.
Do you also work for insurers, property managers and the courts?
Yes. Property managers, housing companies, law firms, insurers and public clients are all among our clients. Which side we act for is clarified in advance – impartiality is the foundation.
Tell us about your building.
The enquiry form asks, step by step, exactly what applies to your case – ticking boxes is enough. Within 48 hours on working days you receive a first technical assessment, free of charge and without obligation.
