Kolkata’s monsoon season brings prolonged humidity and driving rain that attacks UPVC door seals and tracks. Water finds its way past degraded gaskets on older apartment blocks in Salt Lake and New Town, causing frames to swell slightly and locks to bind. Technicians carry marine-grade silicone replacements and stainless-steel screws because standard hardware corrodes quickly in the salt-laden air near the Hooghly.
Many buildings from the 1990s still use early-generation UPVC profiles with narrow reinforcement chambers. When hinges loosen on these doors, the sash drops and scrapes the threshold, a common sight in ground-floor flats around Ballygunge. Repair involves checking the steel insert for rust before re-securing, rather than simply tightening screws that will fail again within a season.

Dust from construction sites along EM Bypass settles into roller tracks and accelerates wear on sliding UPVC doors. Homeowners often notice the door dragging only after the first heavy shower when the accumulated grit turns into abrasive paste. Cleaning the track and fitting new nylon rollers restores smooth operation without replacing the entire door.
Older colonial-era conversions in central Kolkata frequently have non-standard opening sizes. Custom UPVC doors fitted into these frames can develop gaps at the head during summer expansion. Proper repair includes adjusting the top track and adding compression seals rated for 40 °C heat rather than using generic foam strips that compress permanently.
Technician insight
In Kolkata the thing that catches most people out with UPVC Door Repair is monsoon water sitting in the bottom track for weeks. The steel reinforcement inside the frame starts rusting from the inside out on buildings in Salt Lake and New Town, and by the time the door sticks the damage is already past a simple clean-and-lube job.
Salt Lake ground-floor door after July rains
The door had dropped and was scraping the threshold after weeks of standing water. Inspection showed rusted hinges and failed bottom seal on a 2008 profile. We replaced the hinges with stainless units, fitted new EPDM gaskets, and realigned the frame. The door now closes tightly even during heavy showers.
