Which documents do you need?
For insulation and window replacement it is important to have proof of the situation and the costs made. Collect the following items so you can show what was proposed and performed.
- Inspection reports and photos (photo) of the condition of windows and walls.
- Quotes and invoices (invoice, payment) for insulation, installation or glass replacement.
- Permits or technical drawings (application) when applicable.
- Permission or written communication with the landlord (record, document).
- Lease agreement and clauses about maintenance and small repairs (rent, contract).
- Correspondence and notices (notice, form) to the landlord and contractors.
Keep digital copies of all documents and timestamps.
Who pays what?
In most cases the landlord is responsible for major interventions to the building or matters affecting habitability, while tenants handle small repairs according to the lease. Check the exact rules in Book 7 of the Civil Code for tenancy law[1]. If unsure, note who proposed which work and which quotes were given.
Respond to official summons within the stated deadline.
Practical steps when discussing costs
- Ask in writing for clarity about who bears the costs and what work is planned (notice).
- Compare quotes and note which items fall under rent or service charges (payment).
- Create an overview with photos and timestamps as evidence (record).
When to file a complaint?
If consultation with the landlord does not resolve the issue, you can file a complaint with the Rent Tribunal or ultimately involve the subdistrict court. The Rent Tribunal often handles disputes about rent, service charges and some adjustments; keep all your documents and correspondence to support your case.[2]
Detailed documentation increases your chances in a procedure.
