    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

    What Our Customers Say

    Excellent service from beginning to end. I had 4 UPVC sash windows with broken mechanisms. Joe was quick to respond with quotes and the work was done quickly and efficiently by Mike and Everton, who were friendly and left everything clean and tidy. I am very satisfied with the company and highly recommend them. Good value and great work.

    Penny Allen

    It was very easy to deal with Joe, easy to get a quote and arrange a date. Everton carried out the work – he was very polite, clean, timely and did an amazing job. Would definitely recommend.

    David C.

    We used Save Our Sash to refurb seven Victorian single glazed windows and replace one window in full.

    We are so happy with the work- and so pleased we could keep the original timber frames which Joe’s team lovingly sanded and restored. One frame was part rotted which Joe’s team fixed for a very reasonable amount. Couldn’t recommend highly enough.

      Penny Allen

      We had two very old and rotten sash windows replaced with new double glazed wooden sashes and one sash window repaired where the cords had snapped. Everyone from quotes to fittings was very friendly and knowledgeable about sash windows.
      The work took about 3 days to do. The guy that came to do the windows arrived on time and cleaned up each day before leaving.
      We’re very happy with the job done.

      Susan Sanger

      Highly recommended. Top-notch service, communication and work.

      My very very old sash window was not opening. Many carpenters came and left saying that the window needs replacement or would need to be repaired with abseiling (very expensive) due to it being on the 4th floor.

      Save Our Sash assured they could fix it and they did! They booked me in for the next day, it took them around 2 hours to put the window back in operation. They were unfazed by a few technical challenges and showed very strong expertise.
