Common questions

My landlord won't fix a leak or mould. What can I do?

German law lets you formally notify the landlord of a defect (a Mängelanzeige) and, while it goes unfixed, reduce the rent proportionally (Mietminderung). The key is independent evidence. We document the defect, with photos, dates, moisture readings and the likely cause, in a report that backs your notice or claim. We provide the technical evidence; you or your lawyer make the formal claim.

It's a new-build defect, who's responsible?

Defects that existed at handover are usually the builder's responsibility to fix within the warranty period (Gewährleistung), but you must document and report them in time. We give you the dated, photo-documented evidence to support a warranty claim.

Does this work for a shop or office too?

Yes. Commercial tenants and owners need the same independent evidence for a leak or damp in their premises, to push the landlord to act or to support a claim.

What do I get?

A clear, dated, photo-documented report identifying the defect, its likely cause and its severity, written in English, that stands up as independent evidence.
