External Doors
Welcome in Style
The entrance to any home serves many purposes – from providing essential security to creating a strong architectural statement. At Derwen Joinery, we manufacture external timber doors that bring lasting value to every type of property, whether it’s a traditional country home, a period townhouse or a contemporary new build.
Crafted to the highest standards and available in a wide range of bespoke styles, our timber doors combine timeless design with outstanding durability. Designed to impress and built to last, each door is made to enhance both the appearance and performance of your home.
To complete your entrance, we also manufacture bespoke sidelights, fanlights, architraves and porch surrounds. Every element is tailored to complement the architectural style of your property, creating a cohesive and elegant finish that elevates your home’s character.
Have a Project in Mind? Let’s Talk.
At Derwen Joinery, we believe every exceptional piece begins not with timber, but with a conversation. We are genuinely interested in your ideas, your questions, and the unique details that will make your project a perfect fit for your space. Understanding your vision is the most crucial part of our craft. Get in touch with us today to discuss your plans and let’s begin the journey of bringing them to life.

Secure, Stylish and Durable
Our external timber doors are crafted from premium timbers including Accoya, Abodo, Prime European Oak and a selection of high‑quality hardwoods. Each material is chosen for its stability, durability and suitability for long‑lasting external joinery.
To ensure a flawless and resilient finish, every door is treated with our in‑house, high‑performance three‑coat spray system. All components are fully end‑grain sealed and can be finished in any RAL colour or a range of translucent timber tones, with dual‑colour options available for added design flexibility.
For convenience and complete peace of mind, all doors are supplied with factory‑fitted glazing and high‑specification locks and ironmongery sourced from leading hardware manufacturers. These premium components ensure smooth, secure and effortless operation, enhancing both longevity and day‑to‑day reliability.
Bringing together timeless craftsmanship and robust functionality, our doors create an entrance that is both beautiful and secure.
