Why UPVC Fades and What Spraying Fixes
White UPVC does not stay white. Years of UV exposure break down the surface of the plastic, and the result is the familiar yellowed, chalky, blotchy look that makes an otherwise sound window frame drag down the appearance of the whole property. The frames themselves are usually still perfectly functional — the seals hold, the units are intact, the mechanisms work — and only the surface has aged.
Replacing windows purely because the frames look tired means throwing away serviceable double glazing at a cost that easily runs into five figures for a whole house, plus scaffolding, disruption and making good internally. Spraying addresses exactly the problem you actually have, at a fraction of the cost and in a fraction of the time.
It also unlocks colour options that were never available when the windows were installed. Anthracite grey, black, cream and heritage shades transform the character of a façade, and are frequently what buyers and neighbours read as 'new windows' even though the frames are the original ones.
