We’ve been designing, making and installing high quality sash windows from our base in South London for over 30 years. We’ve learnt a lot over that time; honing our techniques, sourcing better and better materials and developing a satisfied customer base whose word of mouth fuels a large part of our business. But while we’ve come a long way since our humble beginnings back in 1985, some things haven’t changed a bit. We’re still family run, we’re still just as dedicated to our craft, and we still believe firmly in a customer-led approach to what we do.

But words are words. We like our work to speak for itself. Have a look through our portfolio of past jobs, or head to our sash windows product page to see what goes into each of our units.

“Lovely work completed by a lovely bunch of guys. Our fitter, Jack, was courteous and professional, and the work was done to a very high standard. He stayed with us and made sure we went over, and were happy with, every detail before marking the job as finished. I would highly recommend Sash Windows of London.” – Lucy Aikens 
“The guys at Sash Windows of London were a pleasure to work with – windows were finished on time, on budget and looking fantastic” – Cheryl
“Excellent craftsmanship – they really took pride in their work and it showed. With friendly service to boot, I’d happily recommend to anyone.” – Greg Mitcham
“We were guided through the whole process, from consultation to installation, and ended up with a great set of windows at a very reasonable cost. They brought along a dummy window to show us during the initial planning stage – something that proved very helpful. The team, Patrick (our fitter) in particular, were very receptive to our ideas, and were very patient!” – Ken and Alison, Morden
