Why Greater Manchester homeowners are upgrading their windows
Greater Manchester took 1,146mm of rain and 20 frost days in 2025. Those freeze / thaw cycles lift seals, warp frames and let moisture creep in behind older glazing. Across the county's 1,178,246 households, 81% live in a house (detached, semi or terraced). That's a lot of Greater Manchester homes with 8 to 12 windows each, plenty of them still on early double-glazing units well past their useful life.
