They performed draught proofing on my window and did an excellent job, it has solved my issue. They are also very good at cleaning up after the job has been finished, would definitely recommend!

Fantastic company, highly recommended. Mark and his team did a full refurb on my sash windows and draught proofed them all. I couldn’t fault their workmanship and attention to detail. They went above and beyond and nothing was too much trouble. My flat is so much warmer now.

We had the sashes in several windows and two sets of French doors replaced with double-glazed units. Mark was also kind enough to help us with a double-glazed skylight we have. He is a very decent and honest guy, his work is of a very high standard and his prices are competitive. We are very pleased we used him rather than any of the other sash window companies we spoke to.

We are delighted with our new windows. Mark Rhodes was at every stage courteous, informative and professional, inspiring confidence from the first time we met him. The work is of high quality, and was done exactly when and how he promised, leaving my flat scrupulously clean and even helping me to rehang my curtains. I recommend him and his company unresevedly.

Mark did a full replacement of 4 sets of Victorian sash windows, and did a really excellent job. The new double glazed sashes looked completely in keeping with the building and the other (original) windows in it. Work was high quality and service friendly and fast. These sort of windows don't come cheap, but I thought Mark's quote was reasonable compared to others and good value for the quality of the product.

Mark Rhodes is a top guy to work with. Fast, efficient and delivers excellent customer service. He replaced all of our sash windows to a very high standard last year and installed double glazing. He came back this summer for a different window (one he hadn’t replaced) that was faulty and he did the job gratis as a gesture of good will. Highly recommend his services.

Mark inspired confidence from day one when he came to quote on replacing every one of our sash windows with hardwood/dbl glazed. The work carried out by he and Anthony was excellent and on schedule, plus they left the place spotless every day. Cannot recommend LDN enough and will be referring business wherever I can. We are very happy customers.

We hired the LDN sash window co on the recommendation of a friend and I can honestly say it's one of the best renovation decisions we've ever made. We looked at lots of sash window companies, but LDN sash truly are an unbeatable combination of superb product, competitive price and brilliant customer service. We had over 10 windows retrofitted and replaced on our Georgian property by Mark and Elliot who were highly professional: punctual, hardworking, courteous, tidy and fast. We now have stunningly beautiful windows (no more ugly secondary glazing!) that keep out draughts, reduce noise and actually open! I've already recommended Mark and his team to our neighbours because the whole experience from first communication through to final installation was exceptional. Bottom line: They really care about doing a great job - go with them, you won't regret it!

I can highly recommend Mark and his team. They were a pleasure to work with and delivered to a very high standard. A thoughtful and conscientious team - thank you!

Mark and his team did an excellent job of reproducing our street-facing Edwardian windows and door in January 2023. The materials and finishes are of high quality, reflecting great craftsmanship, and the installation was meticulous. Mark made sure we were 100% satisfied and took the time and effort for this to happen. We paid a fair price for the value we got. I would recommend Ldn Sash Windows Ltd unreservedly and would work with them again.
