PVC Windows for Decades: Simple Rules for Long‑Lasting Performance

PVC windows can last 20–40 years or even longer — but only with proper installation and regular care. Let’s look at what you need to do to maximise their service life.

Start with quality installation: entrust the job to experienced professionals. Poor installation leads to misalignments, drafts, and rapid wear of the fittings. Make sure all joints are tightly sealed — this will prevent moisture penetration and condensation.

Maintain the window components regularly:

Profile and glass. Clean them with a soft cloth or sponge and soapy water. Avoid abrasive cleaners and harsh brushes — they can scratch the surface.

Seals. At least twice a year, clean them from dirt and lubricate with silicone grease or a glycerin‑based compound. This will preserve their elasticity and airtightness.

Fittings. Every six months, lubricate moving parts (hinges, locks, handles) with a special acid‑ and resin‑free compound. Check the smoothness of operation — if the sash closes with effort, it’s time for maintenance.

Drainage channels. Periodically clear the drainage holes of dust and debris, especially in autumn. Clogging can lead to moisture build‑up and corrosion.

Use the window correctly:

avoid sudden movements when opening or closing;

do not hang heavy objects on the sash;

ventilate the room 2–3 times a day for 10 minutes (in winter, reduce the time to 3–4 minutes, but open all windows for effective air exchange);

remove the mosquito net for winter and store it in a warm, dry place.

Finally, conduct an annual inspection: check the condition of seals, fittings, and profile. If you notice any damage or a loss of airtightness, contact professionals promptly.

By following these simple rules, you’ll preserve the functionality and appearance of your PVC windows for many years to come.
