Why Oxfordshire homeowners are upgrading their windows
Oxfordshire took 696mm of rain and 35 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 288,108 households, 84% live in a house (detached, semi or terraced) — that's a lot of Oxfordshire homes with 8 – 12 windows each, most fitted with early double-glazing units that are well past their sealed-argon life.
