About Durable Doors

Durable Doors supplies made-to-measure composite door sets manufactured by Hallmark, a long-established UK door fabricator. Every door is a solid timber-core slab — not a foam-filled skin — hung in a reinforced frame and manufactured to the millimetre sizes you provide.

How it works

• 1. Choose and measure. Pick a style and colour, then measure your existing frame following our guidance. We manufacture to the sizes you enter.
• 2. We order from the fabricator. Your door is manufactured to order by Hallmark and delivered to your address, UK mainland.
• 3. Your installer fits it.We are supply-only: you arrange fitting. Don’t book a tradesperson until the door has arrived and been checked over.

Something out of the ordinary?

Side panels, toplights, stable doors, fire doors and out-of-range sizes aren’t sold online — but we can usually still help. Request a quote and we’ll come back to you.
