The secure choice for fire safety

We are UK manufacturers of bespoke, fully certified timber fire and security doorsets and screens.

Est. 1989

Established in 1989, Sentry Doors has built a strong reputation for supplying fully certified bespoke timber fire and security doorsets to the social housing, public sector, commercial and residential markets.

The company was formed by Gordon and Carolyn Yates from a desire to offer a reliable solution to fire door safety. Initially a distributor of fire doors and fire doorsets, Sentry Doors moved into manufacturing in 1996, as a means of controlling the quality of its offering and to ensure that its customers’ requirements, which are almost always bespoke, are never compromised.

Not content to be anything other than the best in the market, in 2011 the company made the decision to specialise further, developing premium ultra-high specification timber fire doorsets and committed to be at the forefront of certification and compliance.

The company celebrated its 30-year anniversary in 2019 which was a key milestone and marked the strategic step to further advance its growth plans. As a result, the business became part of the Cairngorm Capital portfolio in February 2019, reflecting a desire for investment from an established management team, led by CEO Ty Aziz and chairman, Jon Gatfield.

The company is intent on maintaining its family-run heritage and traditional manufacturing methods whilst making significant advancements and marked growth plans. There has since been a programme of investment and expansion, investing in a new CNC machine, optimising its production line to perform and expanding its workforce, all with the goal of increasing capacity and shortening lead times so that Sentry Doors is able to be more responsive to clients. In parallel it has broadened its certified product range, expanding the options available to customers.

In August 2022 the company acquired E. & S. W. Knowles & Company Limited (Knowles), making us the UK’s leader in timber fire safety and security doorsets with a combined heritage of 130 years.

All manufacturing is now undertaken in our state-of-the-art manufacturing facilities in Doncaster and Birmingham, UK. With a combined 100,000 sq. ft these purpose-built spaces allow us complete control when it comes to quality manufacturing and has capacity for expansion. The company continues to invest in order to increase productivity and efficiency whilst maintaining our reputation for quality, compliance, and service.

Compliance and certification are the cornerstones of our philosophy, so we test every component of our products as we develop and enhance them.

This commitment to providing reliability in our sector, is why we have invested heavily over the years in both our processes and our people. This, teamed with our family ethos, is why we continue to lead the way in timber fire door safety and security and why we are the supplier of choice for many long-standing partners across all sectors.
