Why PVCu doors start sticking (usually around year 8–12)
PVCu doors sticking in summer and closing loose in winter is one of the most common Loughborough callouts we get. The cause is nearly always the hinges — they carry a 60–80kg door slab and 10 years of thermal cycling wears the pivot point. In LE11–LE12 the fix is usually a 60-minute adjustment on the flag hinges.
