11.03.2025

High-quality windows can last more than 20 years if properly cared for. However, without proper care, even the most expensive double-glazed windows can quickly lose their properties. In this article, we will analyze the key rules for window care that will help keep them in perfect condition for many years.

1. Regular cleaning of the profile and double-glazed windows

How to wash windows correctly?

Use mild cleaning agents without abrasive particles. Avoid aggressive solvents (acetone, alcohol, acids), which can damage the plastic or aluminum profile. Wipe the double-glazed windows and profile with a soft cloth or sponge. Clean the rubber seals from dust and dirt so that they do not lose elasticity.

How often should you wash windows?

2-4 times a year -; depending on pollution and climatic conditions.

2. Seal maintenance -; protection from drafts

Rubber seals protect against drafts, moisture and cold. Over time, they can dry out and crack.

How to extend the life of seals?

1-2 times a year, wipe them with a damp cloth. Apply silicone grease for elasticity and protection against cracking. Make sure that the seals do not warp when closing the window.

3. Lubrication of fittings -; the key to smooth opening

Hinges, locks and mechanisms require regular maintenance so that they do not jam or creak.

What to do?

1 time a year, lubricate the fittings with special window oil (WD-40 or similar). Check if the sash is warped -; if there is, adjust it. Clean the mechanisms from dust and dirt.

4. Checking and adjusting the sash pressure

In summer and winter, windows operate in different temperature conditions, so it is important to change the degree of sash pressure.

How to adjust the pressure?

In the warm season -; loosen the pressure for better ventilation. In the cold season -; tighten the pressure to avoid drafts.

Adjustment is performed with a hex key -; if you are not sure, it is better to contact specialists.

5. Inspection of drainage holes -; moisture protection

Window profiles have drainage holes through which moisture is removed. If they get clogged, condensation or even mold may appear.

How to check the drainage?

Inspect the holes 1-2 times a year. Clean them with a thin wire or a cotton swab. Rinse with warm water if necessary.

6. Protecting windows from mechanical damage

Do not slam the sashes -; strong blows can lead to deformation of the frame and glass unit. Do not hang heavy objects on the handles and fittings. If the window jams -; do not try to close it with force, it is better to check the adjustment.

7. Additional recommendations

Do not leave the windows in micro-ventilation mode all the time -; this can lead to wear of the seals. In severe frosts, do not open the sashes too abruptly -; the glass unit can crack due to a sharp temperature drop. If drafts appear -; check whether the seals need to be replaced or the sash needs to be adjusted.
