Follow the product instructions
Maintenance differs by frame, glass, hardware and finish. Obtain the manufacturer’s instructions and use the specified cleaning and lubrication methods. Avoid a generic treatment that could harm a coating, seal or finish. Ask the installer to demonstrate operation, locks, screens and any cleaning position before handover.
Keep drainage and airflow understandable
Know which visible openings are intended to drain and do not block them as a quick draught remedy. Keep room-side airflow in mind when positioning furniture and coverings. If moisture persists, record where and when it occurs and have the cause assessed rather than assuming all condensation is a warranty defect.
Keep an opening-by-opening record
Store model numbers, labels, finish details, installation date, warranty contacts and photographs with the window schedule. Record any service visit and the work completed. For a phased project, this also helps later orders match the earlier installation without relying on memory or a colour name alone.
Respond to changes early
Report sticking operation, failed hardware, recurring water entry or visible deterioration through the agreed service channel. Document the symptom and avoid forcing a sash or making unapproved modifications. A concise history helps distinguish a new problem from an unresolved earlier one and supports a more efficient service assessment.
Questions worth asking
- Have the actual care instructions been supplied?
- Are operation and cleaning modes demonstrated?
- Are drainage paths and room airflow understood?
- Can every opening be identified for service?
