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. 56% of the county's 1,280,870 homes were built before 1965, back when single glazing was the norm. Retrofitting those windows is usually the single biggest heat-bill saving a homeowner can make. The county also carries 3,943 listed buildings on the National Heritage List. On those homes a full window replacement is not an option and secondary glazing is usually the route.
