Sash Window Repairs for Islington’s Period Properties

Islington is known for its elegant terraces, townhouses, and conversions, many of which still retain their original sash windows. Over time, these windows can develop common issues due to age, weather exposure, and general wear.

Homeowners in Islington frequently contact us about:

  • Draughty sash windows
  • Windows that stick or won’t stay open
  • Broken or frayed sash cords
  • Timber decay and frame rot
  • Rattling windows and heat loss

Our approach focuses on repair rather than replacement wherever possible, helping you maintain the value and authenticity of your property. To learn more about how sash windows work, see our guide on what are sash windows.
