How to Extend Service Life of PVC Windows: Proven Methods

1. Clean seals regularly with a soft cloth and soapy water to maintain their elasticity.
2. Lubricate hardware 1–2 times a year with specialised products (avoid oil).
3. Check sash compression — adjust eccentric bolts for a tight seal.
4. Clear drainage holes of dust and debris to prevent water accumulation.
5. Avoid abrasive cleaners — they scratch profiles and glass.
6. Do not leave sashes open in ventilation mode for long periods in strong winds.
7. Protect windows from mechanical damage (e.g., during renovations).
8. Schedule professional maintenance every 3–5 years.

These simple steps preserve airtightness, thermal, and acoustic insulation for decades.
