  • We were actually considering replacing our sash windows when we met with Gary to discuss renovation. They were able to offer exactly what we wanted - replacing the glass in the sash frames with double glazed units. The wood and sills were repaired and the windows really do look and work great again. We are so glad we decided to keep them. Gary and his team were really helpful and informative and got the work done very quickly. Thanks!

  • Very impressed with the service from Sash Window Preservation. Staff dealing with the quote were very helpful and professional nothing was too much trouble even when I changed the requirements. The work was completed on time to a very good standard and the refurbished sash windows have really improved the overall appearance of my Cambridge house. The windows are no longer draughty and the house is quieter - now looking forward to cheaper heating bills
