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

Mark was polite, tidy, efficient and so easy to deal with. I would highly recommend his company.

Mark refurbished my sash windows. He and his team worked quickly and very tidily. I am very pleased with the result and Mark was great to deal with - honest and went the extra mile to make them perfect.

We used LDN Sash Window Company to carry out a mix of refurbishment and double-glazed replacements at our offices - around 30 in total. Mark and Elliott who carried out the work were both excellent and we built up such a rapport with them - they were flexible with their start/finish times and hard working! We found LDN competitive, and we are very happy with the finished product too! We would go back to LDN every time! Thanks Mark and Elliott!
