“I had three new windows made and fitted into the existing sashes in a bay window in a first floor flat. The windows were made of wood and double glazed and partly in stained glass. The existing, 100 year old sash boxes were repaired. The work was all done to a very high standard and the end product is perfect. Tom and his team were easy to talk through the scope of work and got a quote across quickly. The fitting team was great to chat to and gave updates on the whole process. At the end, the place was spotless. Couldn’t recommend them enough!”

Highlights
“We had several window frames and double glazed windows installed by Landmark Windows over a period of time in 2020. They delivered a high level of craftsmanship and were extremely considerate and timely, always on time, always leaving the our home spotless and their team are always extremely friendly and go above and beyond. The frames themselves are of an extremely high quality finish and we are extremely pleased with them. Would work with Landmark again without question.”
“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.”
Detailed reviews
Steve and Tom have done small jobs for us in the past. like building a bookcase. This time, we asked them to replace all the frames, doors and double-glazed windows at the back of our four-storey warehouse-type house. These had been constructed from softwood, which had deteriorated over the thirty years since construction. It was a huge job. Steve and Tom and their team did it to an extraordinarily high standard of craftsmanship. They manufactured everything in their workshop off-site and then installed it all in a week, all to budget. They were extremely courteous and careful of the security of our house. Their work could not have been bettered. I gathered from Steve that this job, essentially rebuilding the exterior of a warehouse with hardwood and double-glazed windows and doors, was new to them in terms of its scale, and that they are keen to do more work like it. I see a lot of buildings in Docklands that need renovating, like ours. I cannot think of any other company that I would trust to do it.
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.
New wooden sash windows
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.
New patio door and stained glass windows.

Replacement of staircase handrail and spindles
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.
