Warranty documents

1. Check the full set of documents from the developer

• Developer warranty – a document specifying the warranty period (usually 5 years) and how to report defects.
• Warranty cards for equipment and fittings – stamps and dates from manufacturers of heating, electrical systems, windows, elevators, etc.
• User manuals – installation and operation instructions for boiler, heat pump, ventilation systems, household appliances and smart-home systems.
• Energy performance certificate – confirms the energy class of the building/apartment.
• Statement on tightness and pressure testing of plumbing and heating systems – protocol confirming that the systems were tested.
• Handover protocol – list of defects reported at handover along with deadlines for their repair.

2. Organize your document archive

• Create one place for paper and digital copies of each warranty card and manual.
• Label files with the handover date and document type (e.g. “Warranty_windows.pdf”, “Manual_boiler.pdf”).

3. Initial inspection and deadline control

• Check from which date the warranty/guarantee is valid (see handover protocol date).
• Mark warranty expiry dates (developer and manufacturers) in your calendar.

4. Reporting defects – step by step

• Document the issue
• Take photos of the defective elements, noting the date and location (e.g. “2025-08-08 – leak under sink”).
• Complaint protocol
• Complete the developer’s complaint form or your own: describe the defect, attach photos, and refer to the warranty document you are basing the complaint on.
• Deadline for submission
• Developer warranty: 5 years from the date of handover.
• Manufacturer warranties: various durations (usually 2–5 years), check the warranty card.
• Submission method
• Email with attached protocol and scanned warranty cards; keep confirmation of delivery and read receipt.
• If the developer offers a client portal – upload documents there for a digital record.

5. Developer and contractor obligations

• Acknowledge the complaint within 7 business days.
• Fix defects according to warranty terms – usually within 30–60 days.
• Provide written notice upon completion and schedule a follow-up handover.

6. In case of delays or refusal

• Send a formal notice (email + registered letter) with an additional deadline (minimum 14 days).
• Request an independent expert opinion if the developer denies the defect.
• Seek legal or mediation support, and if needed, take legal action for substitute performance or compensation.

7. Second handover – repair acceptance

• Once defects are fixed, arrange a follow-up handover.
• Check if the repair aligns with the initial protocol and warranty terms.

8. Keep documentation until the end of the longest warranty

• Retain all confirmations and protocols until the expiry of the longest warranty period.
• This will simplify any further claims and help protect your rights.

• Thanks to this guide, you’ll always be ready to effectively use your warranty documents, report defects on time, and protect your rights as a homeowner.
