Prime are a local family business working to the very highest of standards.

In 2005, Jason and Samantha Coates moved to North Devon to be closer to their extended family. From 1994, they have been involved in the double glazing industry. Originally in Hampshire and Surrey, their considerable experience has since proven invaluable within Devon and Cornwall.

In August 2011, Prime Windows opened their new showroom in Holsworthy – the showroom has been meticulously built and the attention to detail is simply stunning. Each display has been designed and finished to an exceptional standard. 


Prime Windows and Doors have, for quite some time, worked in partnership with Origin-Global who manufacture the Easifold aluminium bi-fold door system allowing Prime to cover the entire South West region with their products. Origin-Global have stringent vetting procedures in place for such a partnership and Prime are delighted to have met their criteria. Their customers comment that the team offer an honesty and reliability of service that is second to none. 

Why not let Prime guide you through your double glazing, conservatory or bi-fold project? They believe the best decisions follow the best advice.
