    Do you need sliding sash window installation in Raynes Park, SW20

    Raynes Park in southwest London features a mix of Edwardian and Victorian homes, many of which showcase period architectural details such as bay windows, decorative brickwork, and traditional sash windows.

    Modern developments and contemporary apartments complement the historic properties, offering a diverse range of housing options. We can supply and fit sliding sash windows to suit all properties.

    If your home’s sash windows fail, replacements could be the perfect solution. Draughty windows can cause heat loss and rising energy bills, but new, well-sealed sash windows significantly improve insulation. Double-glazed replacements also provide excellent soundproofing, reducing street noise and disturbances from neighbouring properties.

    Condensation and moisture buildup on your windows may indicate poor insulation, potentially leading to mould – issues that replacement sash windows can resolve. Additionally, if your windows stick, are difficult to open or close, or have damaged frames or hardware, new sash windows can restore functionality while enhancing your home’s aesthetics.

    I had 8 box sash windows replaced and chose London Box Sash Windows because they offered acoustic glass and coloured glass to match the originals. The work was done in 3 days and the job was difficult because the original windows & frames weren’t straight. The guys did a brilliant job and I am really pleased with the new windows. I wouldn’t hesitate to recommend the company.

    What a fantastic company . Professional from start to finish . We have had wood sash windows replaced in our Victorian terrace house . The product and the work carried out was amazing – we are so happy with the result . From the sales team to the fitters, everything went smoothly and we now have beautiful, period appropriate wood sash windows. It was so worth the cost. We couldn’t be more pleased . Would highly recommend the London Box Sash window company.

    Had new double glazed sash windows installed on one floor and came back to them for another floor a year later. A friendly and knowledgeable team, great product and professional service.

    We could not be more pleased with the service we received from London Box Sash Windows. The process from start to finish was very easy from Jake who came to quote, Judith in the office and Andy who came to install were super helpful. The windows are great quality and Andy did a fantastic job, we have rather a "drunk" Victorian house, our bathroom ceiling in particular, Andy has done such a good job, it looks amazing. He was also very clean and tidy. A huge thank you to Jake, Judith and Andy

    London Box Sash replaced all the sash windows at the front of my Victorian house including a dormer, and a kitchen casement window. Every aspect of this company’s service was friendly, efficient and highly professional. The windows themselves are perfect with a 50 year guarantee and the fitters were extremely competent and completed the task very quickly. They also took exacting care not to leave any mess, building a floor to ceiling screen around all the work and covering every inch of floor. I was particularly impressed with the initial survey, where my needs were listened to so that what was installed exactly met my requirements. I chose the company’s ‘standby’ offer since I wanted the work done fairly quickly, and they were accommodating enough to fit it within the dates I could do. The customer service was also everything I could ask for, and when a blind couldn’t be refitted and there was a problem with rehanging a curtain rail, I was compensated. It was one of the higher quotes I received, but completely worth it, and the standby reduction made a difference. I can’t recommend too highly.

    We asked Simon to come and quote for replacing 6 tired windows – 3 casement and 3 sash windows. Simon arrived on time and was very polite. What impressed me most was his honesty and integrity. He asked how long we intended to stay in our home and he did a thorough review of the condition of our windows and then said, we would be better off just repairing them. In this day and age it's rare to find someone not trying to force sell things to you. Chapeau. Rest assured we will use this company in the future when we do need to replace our existing windows.
