A trade supply service that never compromises

Here at Dempsey Dyer, we successfully combine high quality products, efficiency and reliability – without compromising on any of these aspects. Part of this success stems from our experience – the company has been offering a high quality trade supply service since 1977. We also have a genuine passion for positively impacting the fenestration and home improvement industries.

How do we ensure that our product line is always up to date?

We are proud to manufacture many of our own products, and to supply others from market leading systems companies, including high performance uPVC conservatory roof designs. This means that quality control and high standards are also a priority.

To ensure that you are always supplied with the latest advances available, we have a dedicated Research & Design team. These experts go above and beyond to continually develop our products, whether timber or uPVC in composition. We have recently widened our product line to offer aluminium bi-fold doors too, meaning you can target more customers than ever before.

The development of our timber products includes researching the potential of new finishes, new ironmongery and the latest wood species available, such as Accoya.

In terms of uPVC products, the R & D department are constantly improving the design of products and also developing new options. For example, in 2011 we launched the Beaumont Range. This high performance patent-pending design highlights our duty to providing the most up to date products available, and those that will help you to enhance your business.

A fantastic team behind a fantastic service

The success of our trade supply service wouldn’t be possible without our team of experts. Whether researchers, customer service, sales-based or in other sectors, every one of our 120 employees brings something key to Dempsey Dyer.

We are a company that not only values its staff, but one that values its customers. It is this ethos that lies behind our reliable trade supply of windows, doors and home improvements.
