Choices, choices, choices...

There are so many options for you to consider, from the door style and glazing to the colour, furniture and locking systems, that the question will not be "do I want an Endurance Door" but "which one do we want, and with which knocker?"

Where do we start?

We suggest either designing your own door using out state of the art online door designer, browsing the Endurance Doors brochure, looking at some of our existing work in our Gallery, checking our range of special offer doors or even just emailing us a photograph of your current door and asking for some design inspiration!

Through colour - not paint!

The skins of our premium Endurance Doors range of solid core composite doors is moulded over actual timber using a mix of coloured thermoplastic, meaning your door will be the same colour should you accidentally scratch it and will not fade, peel or require painting or touching up in the future. These colours are available on the inside of the door as well, and most are available on the door frame. 

Lok out for the 2 brand new colours in the collection - Sage and Brilliant Blue!

Rob was helpful from the start always there for any questions I had. 
I work with multiple pvc manufacturers as I own and run a property improvement company and Cardiff composites service was professional with a quality product will definitely be using them again.
