Sash Window Restoration, Refurbishment & Repairs in Angel, Islington

At Barnsbury Joinery we provide a comprehensive sash restoration service, upgrading the thermal and acoustic performance of a building through in-depth repairs, draught sealing and restoration across Angel, Islington. With the support of our joinery and glazing workshops, we are equipped to manufacture any necessary components to rebuild your sash windows to their original detailing.

Problems commonly encountered include water ingress, decayed or painted shut components, rotting sills (particularly on south and west elevations), draughts and damaged glass. These sash windows have often been neglected for long periods, and show signs of poor quality repair in the past, with filler being applied directly to damp and decayed timber, then painted over.

As standard, we will quote for refurbishment, in-depth repair and draught seals. These go a long way to bringing a single glazed window to proper functionality and if carefully painted, should give many more years of service. At Barnsbury Joinery we provide the following sash restoration service across Angel, Islington:

  • Remove beading and carefully remove top and bottom sashes​
