The word warranty needs an explanation. Ask which work or products are covered and how a possible defect is reported.
Allow for later maintenance
Keep service routes with the room plan. The information helps when a bedroom later needs a different arrangement or use.
Distinguish arrangements
Workmanship and product warranties can have different conditions. Identify the contact person and documents supplied at handover.
Discuss maintenance
Some conditions relate to normal use and care. Ask what is expected and how maintenance can be recorded.
Make reporting practical
Photographs, location and a description of when the issue appears help assessment. The next step depends on the actual situation and agreements.
How to review the result
Rehearse an ordinary evening: cooking, a video call and someone going upstairs. Check whether doors, connection points and lighting support the agreed uses.
Decide this before construction
Decide which room remains available for quiet and study during the work. Do not automatically schedule kitchen and bathroom disruption in the same phase.
Questions for your own property
- Which arrangement applies to each part?
- Who handles a report?
- Are conditions and care instructions written down?
