Contract Works

Our Contract works team undertakes projects in the Commercial, Education, Leisure, Health and Residential sectors. We have carried out contracts on some of the countries most recognisable buildings, from new innovative designs to the restoration of listed buildings steeped in history


Small Works

Our small works team deals with small projects and refreshments below £15,000. In addition we provide tailored proactive and reactive maintenance packages specific to client needs and a highly responsive 24 hour call-out team dedicated to dealing with emergencies.


Metal Works

Our Metal works and fabrication team meets the growing need for specialised components required for the cladding industry, enabling shorter lead in times whilst delivering consistent quality and negating reliance upon external suppliers.



Thornton is a leading roofing and cladding company based in Northern Ireland delivering projects across the UK and Ireland.

Established 50 years ago Thornton prides itself it in its ability to deliver high quality workmanship, exemplary customer service and value for money.

We employ more than 80 people and in 2016 initiated an ambitious business development strategy aimed at growing our capacity and presences in our three core operating sectors of contract works, small works and metal works.

We are proud of our reputation as being the go-to one-stop construction services company for building clients.
