Checklist Window & Door Seals for Tenants in Germany

As a tenant in Germany, it is important to carefully document window and door seals when moving out. This checklist explains in practical terms how to identify seal problems, collect evidence and inform the landlord correctly so that unjustified claims do not arise. The guide helps you to observe deadlines, secure photos and measurements, and to name the right authorities in case of a dispute. Our tips are oriented to the obligations under tenancy law and show which steps you should take immediately to protect your rights.

Why documentation matters

Damaged or missing seals can cause drafts, energy loss and moisture. As a tenant you should report defects in writing at an early stage; according to § 536c BGB, a defect that is not reported in time can make it more difficult to fend off claims. Documentation with date, photo and short description is crucial if it later comes to questions of liability or compensation.^[1]

Practical checklist

• Take photos and videos with date and time (inside and outside) — close-ups and overall views.
• Note measurements: gap width, condition of rubber, width of the seal and affected windows/doors.
• Send a written defect report to the landlord (email + registered mail if necessary) and keep copies.
• Document date and time of every communication and request a confirmation of receipt.
• When handing over keys and final inspection, insist on a protocol; document deviations photographically.
• For legal questions or eviction suits, the local court (Amtsgericht) is generally responsible; seek advice in time.^[3]

How to report defects

Keep your message brief and factual: describe location, type of defect, date of discovery and a reasonable deadline for repair. Request confirmation of receipt. If you want a repair, state an appropriate timeframe — for heating-related seal problems within a few days, for other defects within 14 days depending on urgency.

Rights and deadlines

In case of significant defects, a rent reduction may be possible; timely notification to the landlord is required. Check the BGB paragraphs on defects and notification duties, especially §§ 535 ff. and § 536c on the duty to notify.^[1] For court actions the Code of Civil Procedure (ZPO) applies.

FAQ

Who pays for repairing the seals?

In principle the landlord is responsible for maintenance, unless the damage was caused by the tenant or contractually agreed otherwise.

How quickly must I report a defect?

As soon as you notice the defect. Immediate written notification protects your rights and obligations.

What happens if the landlord does not respond?

You should follow up in writing and set a deadline; if there is no response, rent reduction, self-remedy or legal steps may follow.

How-To

1. Photograph the window/door systematically: overall shot, close-up of the seal and a photo with a tape measure.
2. Create a written defect description: location, date, measurements, possible consequences (drafts, moisture).
3. Send the defect report by email and obtain confirmation of receipt; if no response, send registered mail.
4. Set deadlines (e.g. 14 days) and document them; in case of danger to health or the dwelling, demand immediate action.
5. If no agreement is reached, collect evidence and consider legal action at the local court.
