Top quality replacement windows
Customer Service
Steve, Tom and their team replaced our original late-Victorian bay windows with hand crafted, modern double-glazed units. Top quality workmanship, considerate and friendly workers and great attention to detail. Would heartily recommend Landmark to anyone who wants high quality windows.

Front Bay Windows
Customer Service
Excellent job, the windows look great and very conscientious and professional. Would definitely recommend them. I am using them to make bespoke bifold doors for the rear extension.

Replacing windows
Customer Service
I had all my windows replaced in my flat. Steve and Tom came highly recommended. They sent me a quote soon after they had seen my flat and had taken the measurements of the windows. The work was done to a very high standard and the work was completed on time and the flat was left in a clean state and I would highly recommend Landmark Windows Co. Ltd.

I had three windows completely replaced and I couldn't be more satisfied! Nothing was too much trouble and they were a pleasure to have in the house (not something one can say often about builders). They left everything clean and tidy, and were happy to move heavy furniture for me. The windows work beautifully and I would recommend them to anyone.

Purpose made windows
Customer Service
Landmark made me several wooden double glazed windows for a job I had in a conservation area. The windows were of a very high standard and were passed by the Hampstead Suburb Garden Trust, not an easy task.

Excellent attention to detail
Customer Service
We had one large window redesigned and replaced in hardwood, plus another three casements replaced in hardwood. The attention to detail was outstanding. We were extremely pleased with the results.
