We are a 120-strong team today, many of whom have been with us for more than 20 years.

How has Dempsey Dyer changed over the years?

1977 – 1980

The first few years were spent developing timber products for trade customers.

1981 – 1990

The 1980’s saw the introduction of uPVC production to Dempsey Dyer Ltd. Our trade customer base began to increase with orders from across the country.

1991 – 2000

This period saw business increase as Dempsey Dyer became well known in the Fenestration Industry for the quality of our products.

2001 – 2010

Our commercial customer base expanded providing Dempsey Dyer with a solid understanding of commercial customer requirements. From 2005 a large investment was placed into upgrading the uPVC area of Dempsey Dyer featuring new machines linked together with industry software to streamline our quoting, ordering, production and loading processes. As from 2009, similar investment will be seen in the timber production area of Dempsey Dyer.

2011 – Present

Arguably the most exciting period in the company’s history, 2011 onwards has so far seen the introduction of a new patent-pending product; “The Beaumont” together with the launch of several new products in both timber and uPVC. In the second quarter of 2012 a contract was signed with two well established software firms to provide one common platform for the company to help streamline efficiencies.
