Why Warwickshire homeowners are upgrading their windows

Warwickshire took 670mm of rain and 32 frost days in 2025 — the freeze / thaw cycles that lift seals, warp frames and let moisture creep in behind old glazing. Across the county's 253,262 households, 85% live in a house (detached, semi or terraced) — that's a lot of Warwickshire homes with 8 – 12 windows each, most fitted with early double-glazing units that are well past their sealed-argon life.
