Why homeowners in Greenwich replace their windows
Energy efficiency. Many homes in Greenwich still have older double glazing fitted in the late 1990s or early 2000s. Modern A or A+ rated units cut heat loss significantly and reduce annual energy bills.
Noise reduction. Acoustic glazing reduces traffic and street noise by up to 75%, a common upgrade on properties near main roads, railways or busy junctions.
Curb appeal and value. Estate agents in Greenwich consistently cite new windows as one of the highest-return upgrades before listing a property for sale.
