How to Extend Service Life of PVC Windows: Proven Methods
- Clean seals regularly with a soft cloth and soapy water to maintain their elasticity.
- Lubricate hardware 1–2 times a year with specialised products (avoid oil).
- Check sash compression — adjust eccentric bolts for a tight seal.
- Clear drainage holes of dust and debris to prevent water accumulation.
- Avoid abrasive cleaners — they scratch profiles and glass.
- Do not leave sashes open in ventilation mode for long periods in strong winds.
- Protect windows from mechanical damage (e.g., during renovations).
- Schedule professional maintenance every 3–5 years.
These simple steps preserve airtightness, thermal, and acoustic insulation for decades.
