I've used Lee for a number of jobs over the last few years, and if I wasn't happy with what he did I wouldn't use him again. Nice guy that he is. The most recent job last week was to replace a radiator with two smaller ones. This was the first time I had met Mark, Lee's colleague. I can only say that he was nothing less than excellent in every respect. The work he did was very impressive and equally as important his ability to not make someone who knows nothing about plumbing, feel like they know nothing about plumbing. As I was curious as to how exactly the job would be done and how it would look, he was very calm and patient in explaining everything. I was very happy with the end product (again), and wouldn't hesitate to recommend them to anyone.
