About Us

In 1989, David and Eddie Martin set up Design Window & Door Systems. Having both worked in the glazing industry, their aim was to provide a first-class fabrication and manufacturing service to the window installation trade. Originally established in Mayland, Essex, and employing only a couple of engineers, it was a drive for delivering a cost-effective, high-quality product that determined the direction of the business.

27 years later, Design Window & Door Systems is still a family business. David and Eddie are still directors and work from the much larger 25,000 sq. ft. facility near Chelmsford, Essex.

With over 50 employees and a strong senior management team, we supply uPVC windows, doors and conservatories to installers all over the South of England and beyond.
