Why Somerset homeowners are upgrading their windows
Somerset took 864mm of rain and 24 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 424,018 households, 83% live in a house (detached, semi or terraced) — that's a lot of Somerset homes with 8 – 12 windows each, most fitted with early double-glazing units that are well past their sealed-argon life.
