COMPANY HISTORY

Masterdor Limited was established in 2014 when Synseal Group bought the assets of the door business based at Nether Heage in Derbyshire.

With an investment of £1.5 million, Synseal Group has transformed Masterdor into one of the UK’s best known door brands, working with housing associations, councils and new build developers across the UK to provide secure yet stylish entrance door solutions.

The company’s flagship products – Masterdor engineered timber doors and Suredor GRP composite doors – are two of the most highly specified entrance doors in the UK, and have been designed to offer specifiers a wide choice of colours and style without compromising quality, security and longevity.

In 2018, Masterdor launched Warden Fire Doors, the first timber fire doors in the UK to be comprehensively furnace tested on both sides to 2018 British Standards. In response to the findings of the Hackitt review, Warden Fire Doors are only sold with a valid 2018 test report for your exact specification.
