2002 The Grey Accumulation
The sky committed to grey and stayed there. 158 wet days and counting — the quiet beginning of a 25-year accumulation.

2002 — The fine, persistent drizzle of 2002 is the most damaging weather type for exterior glass and UPVC — not because it is dramatic, but because it deposits without flushing. Every grey, drizzly day that year left a thin film of dissolved minerals and organic particulates on every surface in the region. Individually invisible. Collectively, after twenty-three years, the reason your windows no longer look clean even after rain.

ONS Consumer Spending
ONS: UK house price growth hit 25% in 2002 — the fastest rise in a generation. Homeowners were property millionaires on paper but spending nothing on maintenance.
October 2002 brought severe gales across southern England, with gusts recorded above 60 mph across the East Midlands. The autumn delivered wave after wave of Atlantic frontal systems. But the more insidious damage of 2002 was not the drama — it was the relentless drizzle. Fine rain does not wash glass. It deposits a thin film of dissolved minerals and atmospheric particulates that dries invisibly. Repeat this process 162 times across a year, and the cumulative deposit is measurable. By 2002, properties that had gone two or three years without a professional clean were beginning to show the early signs of what we now call first-generation limescale — not visible as a crust, but present as a permanent haze.
Nice weather for estate agents. Britain in 2002 was obsessed with property values and completely uninterested in property maintenance. Everyone was watching their house price go up and ignoring the fact that their windows were slowly turning opaque. The great British moan of 2002 was: the weather's terrible, but at least the house is worth more. It was also the year of the October gales. Fences down. Tiles off. Classic.
Fine persistent drizzle with no wash-off action accelerated surface mineral bonding without flushing deposits; biological bloom velocity building (BBV 3/10); October gales created first fascia stress points; approximately 440 stewardship hours available before the grime began to set.
BIO-BLOOM VELOCITY
BBV 3/10 — Building. Fine drizzle deposits without flushing. First layer of organic film forming.
INFRASTRUCTURE STRESS COEFFICIENT
Primary Stress: Surface Staining — 50%. Persistent fine rain with no flush-through creates permanent organic film on UPVC and glass.
STEWARDSHIP WINDOW
440 hours. Standard workable year. The fine drizzle that created the staining also made many potential treatment days marginal.
MOAN-O-METER
5/10. Gale on 27 October briefly elevated national irritation. Otherwise the standard British complaint issued on repeat.
