As a tenant in Germany, you may face questions about silicone seals and possible moisture damage when moving out. This guide explains clearly which obligations tenants and landlords have, how to inspect silicone seals, detect damage early, document properly and when repair or professional rehabilitation is necessary. You will also learn how to meet deadlines, collect legally reliable evidence and which forms or courts in Germany are responsible. Practical checklists help avoid disputes at handover and protect deposits. At the end you will find a short documentation guide, FAQs and links to official bodies such as the BGH or the Federal Ministry of Justice.

What tenants need to know

As a tenant you are entitled to a defect-free apartment; the landlord is responsible for maintenance, especially for moisture and mold, see the BGB. [1] Check silicone seals regularly for cracks, discoloration and missing sealant. Small cracks or porous seals can be first signs of moisture damage; act early and appropriately.

In most regions, landlords are responsible for maintenance of seals.

Documentation is central: date, location and several photos from different angles help in later disputes. Send defect notices in writing and request a deadline for repair.

  • Take dated photos of seals with location notes.
  • Assess whether seals can be superficially renewed or if a specialist is required.
  • Send a written defect notice to the landlord (email or registered mail) and set a deadline.
  • Check repair costs, deposit issues and possible cost allocation.
  • Create a handover protocol with photos and signatures.
Photo documentation with dates strengthens your evidence.

FAQ

Do I have to renew silicone seals when moving out?
Normal wear is usually not chargeable; if seals are damaged due to improper care, the landlord or a lease agreement may affect liability.
When can I reduce rent because of moisture?
For significant impairments to habitability (e.g., mold, persistent moisture issues), tenants may reduce rent under the BGB if the landlord does not remedy the problem promptly.
Where do I turn in case of dispute about seals or moisture damage?
If disputes cannot be resolved, the local district court (Amtsgericht) is responsible; case law from higher courts like the BGH provides guidance. [2]

How-To

  1. Inspect all affected rooms systematically and take dated photos of each damaged or moldy seal.
  2. Write a defect notice to the landlord with images, request a repair deadline, and reference your documentation.
  3. For small defects reseal professionally; for major moisture damage hire a specialist and clarify who bears the costs.
  1. Create a detailed handover protocol with photos and signatures at move-out to avoid later disputes over the deposit.
  2. If the landlord remains inactive, consider legal action at your local district court and present your documentation. [2]
