Why Do Plastic Windows Fog Up? When It’s Normal and When to Worry
Waking up to water droplets on the window? It doesn’t always mean the window is broken. We explain when condensation is normal — and when it’s a warning sign.
Learn how window maintenance needs differ across Lithuanian cities — the influence of climate, building age, and usage intensity in Vilnius, Kaunas, Klaipėda, Šiauliai, and Panevėžys.

Window faults do not appear entirely at random. They are influenced not only by the age of the windows and the quality of the hardware, but also by the city's climate, the type of building, the period when the windows were installed, and the frequency of maintenance.
The same window in Vilnius, Klaipėda, or Panevėžys may wear differently. Wind, humidity, temperature swings, building age, and even how often the windows are opened all differ. As a result seals wear faster in one city, hardware in another, and in a third the primary need is seasonal window adjustment.
Window repair in Vilnius often depends on building type. In new-build flats windows operate smoothly for the first few years, but after 5–8 years the first signs of wear begin to appear: stiffer operation, uneven compression, or gradually weakening airtightness.
In older apartment blocks worn seals, misaligned hinges, a dropped sash, or less precise hardware are more common. In larger flats or offices windows are opened and closed more frequently, so mechanisms bear a greater load — Vilnius window technicians notice this particularly often in commercial premises.
In Vilnius it is worth checking sash compression, hardware condition, balcony door hinges, seal elasticity, and ventilation function more regularly, especially in newer flats.
Window repair in Kaunas is frequently associated with an older apartment stock. Some windows have already been in use for 10–20 years, so seals, hardware, handles, and compression mechanisms naturally begin to wear.
More pronounced temperature swings also affect window operation. In the cold season reduced airtightness is noticed more frequently, and after winter some windows become stiffer to operate. Kaunas window specialists observe that in private houses a more frequent problem is double-glazing unit condensation (moisture between the panes). This is an irreversible fault — the unit is replaced, not repaired.
Window repair in Klaipėda has its own character — the coastal climate means more moisture, stronger wind, and greater load on sealing elements. Damp, salty air accelerates corrosion of metal parts, so hardware hinges and locks rust faster than in inland regions.
For this reason preventive lubrication and seal checks carry greater practical importance in Klaipėda than in most other Lithuanian regions. Klaipėda window technicians recommend seasonal adjustment twice a year: the coastal winter with strong winds requires maximum compression, while summer calls for easing it so the window does not force the frame.
Window repair in Šiauliai often starts with a diagnosis: a common situation is that the window has not yet fully broken down, but the handle already moves more stiffly, the window closes less evenly, or the sash begins to catch on the frame.
The windy climate, cold season, and faster accumulation of dirt affect drainage systems: the holes block more quickly and moisture accumulates. In older apartment blocks, of which there are many in Šiauliai, the standard problem is aged windows with hardened seals. Šiauliai window specialists most commonly perform winter adjustment and drainage cleaning as the primary preventive service.
Window repair in Panevėžys has its own distinguishing feature — the city has the most pronounced continental climate: winters reach −25 °C, summers +35 °C. This ~60 °C cyclic difference acts on PVC profiles more intensely than in any of the other four cities: frames shrink and expand more than in Klaipėda or Vilnius.
The result: compression correction is needed more often, and seals harden faster. Panevėžys window technicians recommend seasonal adjustment twice a year as the standard. Wooden windows that survive in older Panevėžys districts are a separate topic: properly repaired, they can serve for decades more. Window repair in Panevėžys covers wooden, aluminium, and plastic windows — the mix in the city is distinctive even by Lithuanian standards.
The general principle across Lithuania is the same — windows are worth checking preventively at least once a year, especially before the heating season. However, the parts that need more attention differ from city to city.
On the coast moisture and hardware protection matter more. In central Lithuanian cities temperature swings and seasonal compression are of greater importance. In older apartment blocks seals and mechanisms wear more often; in newer ones ventilation and regular compression checks are key.
Window problems differ between Lithuanian cities not because windows in one place are inherently better. The difference is most often determined by climate, building age, usage intensity, and maintenance frequency. This is precisely why symptom alone is not always a reliable guide to what repair is needed — a professional diagnosis and on-site condition assessment give a more accurate answer.
