Established in 1998, Window Mart has gone from strength to strength, culminating in the opening of our new show complex at Old Barn Garden Centre near Horsham. All Window Mart staff are employed by the company and drive fully equipped company vehicles. We have our own building team for groundwork and brickwork. In our showroom, an extensive range of conservatories, doors and windows can be viewed. Excellence is our commitment, and we are here to make sure you get the very best in service and quality.
