Lee Stewart at Stewart & Stewart has been amazingly helpful, kind and responsive to my plumbing problems and not only was the firm referred to me by a wonderful electrician to begin with, but Stewart & Stewart have also referred me to a good warm air heating specialist to help with an ongoing issue. They will go above and beyond to help their customers and do understand the human (and often urgent) element of what they do. I wouldn't hesitate to refer them to friends and family.

I have used Lee and his company for a few years now on a boiler refit and several small jobs. First class work, good price, friendly and quick. What more can you ask for ? 5 stars from me.

I have used Stewart and Stewart for a number of years now and they have always been super reliable and dependable. Lee in particular has been fantastic in understanding clients’ needs and explaining the pros and cons of different available options. Jobs were executed in the most efficient manner with minimal disruption. But above all, it’s the trust that I value most. Thank you Lee and great job!
