Frequently Asked Questions: UPVC Repair Services
Why is my UPVC sliding door hard to slide?+
Sliding difficulty is usually caused by sand grit buildup in the track or worn roller bearings. Replacing the bottom rollers and cleaning the track immediately restores effortless gliding.
Why does my closed UPVC window whistle during high winds?+
Whistling indicates that the sash has dropped slightly or the EPDM gaskets have hardened, breaking the airtight seal. Realignment and gasket renewal will eliminate wind drafts and noise.
