John Barnett started in the glazing trade in the late sixties, after helping his dad sell china at Petticoat Lane Market.
In 2004 he set up Advanced Glazing Systems with his son Andy, and in 2021 Andy's son Tyler joined them.
Three generations, and John is still a managing director.
Ring the office and you'll most likely get Ella, Our Office Administrator. Peter will survey your job, and he's worked with John and Andy for thirty-five years. Gavin runs the installations and spent twenty years fitting before that.
That's the part we're proud of. Twenty-two years, and the same people are still here.
Bailey, Andy's dog, comes in part time and spends most of it asleep in the middle of the floor.
