At Camden Box Sash Windows we provide a comprehensive sash window restoration service, upgrading the thermal and acoustic performance of a building through in-depth repairs, draught proofing systems and full restoration. With the support of our joinery and glazing workshops in both Finsbury Park and Hertfordshire, we are equipped to manufacture any necessary components to rebuild your timber 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 two part filler being applied directly to damp and decayed timber, then painted over.

​

As standard, we will quote for refurbishment, in-depth repair and installing draught proofing systems. This will go a long way in bringing your single or double glazed sash window to properly function and if carefully painted, should give many more years of service.
