Amazing service from start to finish. Staff are knowledgeable and trustworthy! The final product is truly amazing, I would not hesitate to use Landmark Windows again.
Elizabeth Bailey
Landmark windows were great! They made us some bespoke floating shelves and fitted cupboards that look amazing and have transformed our living room. I can’t recommend them enough!
Nathalie Krouglikoff
Quality product and great installation (8 hardwood, double glazed sash windows on the first floor of a Victorian house) at a reasonable price. Product made in North London. Very impressed all round.
Ashley Wright
Over the years Landmark Windows have made perfect concealed cupboards in my office, remade beautiful sash windows, added custom made fitted bedroom cupboards with draws & glass fronts, plus I have stunning french doors onto the garden and there’s nothing that they cannot make in wood!
Margaret Hunt
Landmark Windows have done nothing but exceed my expectations for Service, Value and quality every time that I have used them, both for Window complete replacements and on a restoration/repair job. I would have no hesitation in recommending them to anyone wishing to transform the look and feel of their home. Thank You!
Ian Larke
Outstanding service! Getting quotes were completely hassle free and Steve couldn’t have been more friendly and helpful. Originally replaced and fitted my back bedroom window and got them back to do my front door and downstairs windows. Couldn’t recommend more!
Talia Meisha

I have always used Landmark Windows and their joinery is astounding. I am so happy with my french doors, sash windows, loft storage, bedroom and office cupboards.
Maggie Hunt
Steve Hunt at Landmark Window Co is a very thoughtful and painstaking craftsman. He did an excellent job designing and replacing some windows that were starting to rot. I thoroughly recommend him and his firm.
Paul Butler
We hired Landmark Windows to make some custom made fitted cabinets and shelving in our living room. From the design to the installation they made sure they created exactly what we wanted whilst also informing us, from their experience, what was best for the space…
