About the company

After spending his entire working life in the double glazing industry, Jon felt that there had been a change in the market with window repairs becoming a cost-effective way of keeping existing windows fresh and new.

In 2019, Jon was joined by his son, Jack, to make it a truly family run business, having grown it to a size that can sustain both father and son in employment.
