Premium timber entrance doors, made to measure
A welcoming entrance, beautifully crafted.
Doors do more than provide access. They welcome you home, connect living spaces and help define teh character of your property.
Grampian doorsets combine bespoke design and lasting performance with the natural beauty of Red Grandis hardwood or Accoya.
With a choice of styles, colours and finishes, each doorset is made to complement your project and create a lasting first impression.

Designed around your project
Explore our range of timber windows and doors, with options to suit different styles, specifications and project requirements. From glazing layouts and finishes to ironmongery and detailing, we’ll help you find the right solution for your project.
Any RAL colour, factory applied
From contemporary to traditional, choose the details that best suit your project.
Every Sashless window and door can be finished in any RAL colour. The shades below are the ones our customers choose most often, but they are a starting point, not a limit. If your project calls for a specific colour to match a scheme, satisfy a conservation officer or carry a developer’s house style, we can finish to it. Colours can also be split. You can specify the same colour inside and out, a different colour on each face, or a contrasting frame and sash, in any combination the design needs. All finishes are spray applied in our Northallerton factory using Remmers water-based microporous paints and stains. This gives an even, consistent coat that on-site painting can’t match.
Factory glazed, specified to suit the building
Every Sashless window and door is glazed in our factory using a dry glazing system to BS 6262, with a fully drained and ventilated bead design. Glazing in controlled conditions means a consistent seal and no site glazing to go wrong.
We offer 24mm and 28mm double glazed units, 28mm and 40mm triple glazed units, heritage slimline units for conservation work, and single glazing where a listed building requires it. Our slimline units are Krypton filled for thermal performance in a narrower profile. Glazing bars can be bonded with a duplex spacer for a true divided look, or fully structural where the specification calls for it.
Low emissivity, solar control, acoustic and obscure glass are all available. If a location needs safety glazing under Approved Document K, tell us at order stage and we will glaze to suit.
The Finishing Touches - Quality hardware, fitted before it leaves the factory
Hinges, locks and handles are fitted in our factory, set up and tested before delivery. Every window arrives ready to operate, with nothing to adjust or source on site.
We use established names including Maco and Titon, with a wide choice of handle styles and finishes to suit contemporary, traditional and heritage designs. Sash windows come with matching sash locks and finger lifts, and all fittings, including screws, are anti-corrosion treated.
Friction hinges with built-in restrictors are standard on our casement ranges. Specialist options cover fire escape hinges and handles, lockable restrictors, extended lever handles and folding cam openers for less able users, and manual or electric operating gear for high-level windows. Concealed trickle vents keep ventilation in line with Approved Document F without an unsightly canopy on the head.
Talk to us about finishes for your project and we’ll match the hardware to your design.
Cover that reflects how long our windows last
Every Sashless factory finished window and door comes with a 24-month standard warranty. When installed and maintained in line with our guidelines, this extends automatically to the cover shown below.
Shorter periods apply to translucent stains and heritage slimline glass units.
The maintenance itself is simple: regular cleaning, lubricating the hardware and checking the finish.

Frequently asked questions
What door products do you manufacture?
Single doors, French doors, bi-fold doors and stable doors, all manufactured to your exact opening rather than adapted from stock sizes.
What's the maximum size for bi-fold doors?
Our bi-fold doors are manufactured up to 6m in length, combining large expanses of glazing with timber’s warmth and character, and running smoothly even at larger widths.
Are your doors factory finished and glazed?
Yes. Every door is factory-finished using a Remmers Induline water-based coating system and factory-glazed to BS 6262, giving a more consistent, weathertight result than site glazing.
