Window Repair in Łódź – Old PVC After 20 Years: Cost-Effective Service vs Replacement
Łódź replaced most of its apartment windows during the 1990s renovation wave. Those PVC windows are now 20–30 years old and starting to show it. Find out what actually fails first — and when servicing makes far more sense than full replacement.
Łódź underwent a massive window replacement wave in the 1990s and early 2000s — tenement buildings and housing blocks throughout Bałuty, Górna and Śródmieście were fitted with PVC windows during large-scale thermal renovation programmes. Those windows are now 20–30 years old and require serious attention.
What Happens to PVC Windows After 20 Years?
Profile yellowing and brittleness: cheaper 5-chamber profiles from the 1990s lose plasticisers and become brittle. Yellowing is not just cosmetic — it signals reduced flexibility and a higher risk of cracking during hardware adjustment. EPDM seal failure: seals typically last 10–15 years. After 20 years virtually every seal in a 1990s Łódź window is hard, flat or cracked — causing draughts and condensation on the frame. Seal replacement costs 40–80 PLN per sash and immediately restores airtightness. Hardware wear: scissor hinges, multipoint locking catches and tilt limiters have a 15–25 year lifespan with annual lubrication. Without maintenance, they seize, corrode and lose adjustment precision. Steel reinforcement corrosion: blocked weep holes allow standing water inside the profile, which rusts the internal steel insert and can crack the profile from within — the one failure that cannot be repaired.
Łódź's Wind Problem
Łódź sits on flat upland terrain with few natural windbreaks, giving it higher average wind speeds than sheltered Kraków or densely built Warsaw. Repeated wind loading on scissor hinges causes them to loosen over time, leading to an uneven sash compression — one side seals properly, the other doesn't. Hinge adjustment restores even seal contact and extends hardware life by several years.
Service vs Replacement: The Economics
A full window replacement in Łódź costs 800–2000 PLN per window including installation. A comprehensive service (seal replacement, hardware adjustment and lubrication, worn parts replaced) costs 80–200 PLN per window — 10–20× less. If the profile is structurally sound (not yellowed and brittle, no rusted steel insert deforming the frame), servicing restores full function for another 5–10 years. Replacement is justified only when the profile is structurally compromised or the glazing unit is fogged beyond repair.
