TRADE SUPPLY
Our aim is simple: preserve the heritage of the property while introducing the benefits of modern timber, glazing and manufacturing techniques.
TIMBER WINDOWS & DOORS FOR INSTALLERS
At Landmark Windows, we work with professional installers, builders and window companies looking for a reliable UK manufacturer to supply high-quality timber windows and doors.
Our supply-only trade service gives you access to bespoke joinery at competitive trade prices, manufactured in our own workshop and built to your project requirements.
Whether you need a one-off order or are looking for a long-term manufacturing partner, we can support you with consistent quality, reliable communication and practical technical advice.

Bespoke casement windows

Front, rear and French doors

TRADE PRICES
Approved trade customers benefit from dedicated supply-only trade pricing across our window and door range.
Our aim is to build long-term relationships with installers who want to offer their customers premium timber products without having to manufacture them in-house.
The more we understand your typical projects and requirements, the easier we can make the quoting and ordering process.
YOUR MANUFACTURING PARTNER
Think of Landmark as an extension of your own business.
You manage the customer and installation. We manufacture the products.
Our team can assist with specifications, measurements, glazing options, materials and technical details before your order enters production.
Products are manufactured, spray finished and glazed through our own workshop processes before being prepared for collection or agreed delivery.
A DIFFERENT OPTION FOR CUSTOMERS
Our trade partners can also offer Landmark’s Sash Upgrade Service.
Where an existing traditional box frame remains in good condition, we can manufacture replacement moving sashes rather than requiring the entire window to be replaced.
This gives installers another option to offer their customers, helping preserve original frames while providing improved glazing, draught proofing and performance.
It can also provide a more cost-effective solution than complete replacement.
