Kolkata’s older residential buildings in areas such as Salt Lake and New Alipore often have UPVC installations from the early 2000s that now face constant exposure to high humidity and monsoon downpours. These conditions cause rubber gaskets to harden and tracks to collect fine silt carried in from the Hooghly. Regular maintenance prevents water ingress during the June–September rains and stops hardware from seizing when temperatures climb above 35 °C in May.
Homeowners in Howrah and Behala frequently report sliding doors that drag after the first heavy shower because silt mixes with the original factory grease. A proper service removes this mixture, re-lubricates with silicone-based products rated for coastal humidity, and checks the drainage channels that many installers leave partially blocked. Skipping this step leads to standing water that stains the white UPVC within two seasons.

Every city below has its own local UPVC Maintenance page with coverage details.
Local practice also includes inspecting the screw ports and corner joints that expand and contract with daily temperature swings of 10–12 °C. Tightening these points and applying a light corrosion inhibitor on exposed metal keeps the frames stable without the need for full replacement. This approach suits the mixed stock of single-storey homes and mid-rise apartments common across the Kolkata Municipal Corporation area.
Technician insight
In Kolkata the thing that catches most people out with UPVC Maintenance is the fine silt that rides in on monsoon winds and mixes with the original grease inside sliding tracks. Older buildings in Salt Lake and New Alipore have narrower drainage channels that clog first, so water sits against the seals for weeks. One missed annual clean and you start seeing staining and minor leaks by October.
Sliding door drag after first monsoon
A homeowner in Behala called after heavy July rain left the balcony door hard to move. Inspection showed silt packed in the lower track and hardened grease on the rollers. We cleared the channels, replaced the bottom gasket and re-lubricated with a humidity-rated product. The door now slides freely and drainage holes remain clear.
