LDN sash window co Avis 

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.

A pleasure doing business with Mark & Andrew. Great product with great communication from start to finish. Installation was quick & tidy. I would highly recommend.

The team reburbished 4x 120 year old sash windows and redesigned an 8 year old casement window as well as draft proofed it. All work exceeded my expectations. Ben

Mark made and installed 2 new sash windows at our flat in West London to replace to that were single glazed and getting old. From start to end the process was easy and great and we are very happy with the final result. Recommended.

Superb. Mark replaced the original sashes throughout the house for new doubled glazed and renovated the original frames such that the windows now look like new (for a much more reasonable cost than a full replacement)

Mark and his team were efficient, polite and always extremely careful to keep things as clean and tidy as possible, including cleaning up after themselves at the end of each day. A pleasure to have around the house - they are as unobtrusive as possible. The work product is of a fantastic quality - I am delighted. I would actively recommend anyone to use him in a similar job.

Great service and workmanship. Punctual, clean. Great re-furb on victorian Bay windows. Would use again and would recommend.

Mark replaced our main bedroom bay windows and side window with double glazed windows. He did a very professional job, all done in less than two days, lovely finish and a real pleasure to deal with.

Mark did a great job of installing new, double glazed, replacement sash windows in a Victorian terraced house. His carpentry is excellent and his pricing is very
Competitive. He’s trustworthy, helpful and I would definitely recommend him.

We needed to remove our sash window in order to move our sofa which we couldn’t fit through the front door and hall. Mark understood exactly what was needed and turned up early on the day of the move to do this for us. He is professional and nice to work with, and completed the job quickly and without any issues. I wouldn’t hesitate to recommend this company.

We needed our windows repairing before having shutters fitted.
Mark was very friendly & gave us a quote just a few days after calling, and managed to fit us in the following week! Reasonably priced compared with other quotes and local to wandsworth.
Anthony was very nice and did a great job with the windows - we were very pleased!

Excellent work. We had our sash windows renovated. The communication was good and the work was done on time, to a high standard.

Delighted with my new sash windows. Mark and Anthony have done a fantastic job. The windows are lovely and they have finished off to an amazing standard, way beyond what I expected. They were very accommodating about delays to the installation caused by delays to other work on the building, and then working around various commitments out of my control. They were also very good value for money. I thoroughly recommend LDN Sash Windows.

Excellent service throughout. Windows were installed to a high quality standard and Mark was very accommodating and understanding of our situation with a 9 months' pregnant woman in the house, and made every effort to be flexible around our needs. Definitely recommend this company.

The service we had from Mark was exceptional from start to finish and we are delighted with the French Doors which he made and fitted for us. He understood exactly what was required and was helpful and communicative throughout the process. I would highly recommend Mark and the team at LDN Sash Windows.

Our refurbishment required the re-installation of 8 complete sash windows and box frames. Although I sent dimensions, Mark wanted to visit the site and discuss the project before providing quotes. Mark talked through our options, how his windows were made, glazed, installed and finished. He was extremely thorough which combined with his friendly manner, virtually guaranteed him the work even before quoting. Throughout the project, Mark provided regular updates and delivered on or ahead of the agreed schedule despite this being a period where most other trades on the project were delayed by material shortages. As the refurbishment was not as advanced as we had hoped at installation of the windows, Mark and his colleague Elliot returned to re-touch the window finish after the heavy site work had finished, which definitely went over and above my expectations. I received many quotes for the work and LDN were very competitive on price. I would highly recommend LDN Sash Windows for anyone looking to replace or repair their windows.

I'm very happy with my refurbished windows. LDN was recommended by a friend. Before finding them I had thought that my only option was to completely replace my lovely old sash windows with new ones, at vast expense. Mark came round and explained in detail all the possibilities and prices for dealing with them and gave me a date for the works, that he kept to. Anthony was reliable, arriving when he said he would, tidy, polite, and nice to have around. He did a beautiful job.

Mark was very organised in facilitating the work and keeping me in touch with how things were going. Anthony, who actually did the work, was friendly, efficient, thorough and cleaned up well after he had finished the work. The job ended up being a bit more complicated than first anticipated but there was no question of charging us more. I would definitely recommend LDN to anyone. You may get cheaper quotes elsewhere but LDN provide excellent value for money.

Mark & his team were great. The work was of a high standard, they turned up when they said they would, worked hard, tidied up after & were generally pleasant to have around. Thanks Mark & Elliott
