"John Mahoney was recommended to us by a brilliant restorative stained glass expert who sadly damaged her hand and could not take us on. We met John and he gave us a fantastic and reasonable quote within a few days and came round to help us with a big project on the front door and lounge area. John worked quickly but more importantly with immaculate precision and high production values. He advised on the glass replacements due to our glass being over 100 years old, and found decent replacements. I found John to be trustworthy, timely and good value for the quality. We will definitely be using him again."
