Is it serious, and why is it cracking?
A crack can be superficial or reveal movement in the structure. The difference is measured: orientation, width, change over time, type of ground. That is what we do on site.
What the diagnosis includes
- Mapping of the cracks (position, width, direction, active or stabilised)
- Crack-gauge measurements and tell-tales to monitor movement
- Review of possible causes: drought and clay shrink-swell, settlement, trees, drainage, construction defects
- Written report: probable causes, classification of the defects, order of magnitude of the repairs

Frequently asked questions
Is my crack serious? It depends on its orientation, width and how it develops. The diagnosis is there precisely to determine that.
Can the report be used for insurance (natural-disaster cover, ten-year builder’s warranty)? It is the technical document that supports your file. It does not replace a court-appointed expert report.
I live abroad. Can you act for me? Yes. We can visit the property on your behalf and send you the written report by e-mail.
How much does it cost? The quote is free and without obligation; the fee depends on the assignment.
