Mold in the Flat - Tenancy Lawyer
For tenants in Berlin
If mold appears in the flat, the dispute often concerns health impact, causation, tenancy-defect rights, and how to proceed properly with the landlord.
These are usually the key issues in mold disputes:
- ›Review of whether the mold amounts to a legally relevant tenancy defect
- ›Assessment of causation, documentation, and the landlord's response
- ›Evaluation of whether a rent reduction may be justified
- ›Clear lawyer guidance on the most sensible next step
You receive a clear first assessment of how the mold situation should be assessed legally.
Important to know: In mold cases, documentation, causation, and clear communication are especially important.

Mr. Lerch provided me with highly professional, calm, and dedicated support throughout my legal proceedings. I particularly appreciated his honest assessment of my case and the clear communication he maintained throughout the entire process. Thanks to his strategy and preparation, we achieved a significantly better outcome than originally anticipated in the penalty order. I felt well-advised and taken seriously at all times. I can therefore wholeheartedly recommend Mr. Lerch and thank him again for his support. B. Paal
