Professional, honest, trustworthy...I will not think twice before hiring again.
I asked for some work to be done based on my knowledge and what other "big name" company plumbers told me was required. First, the quote I received was based on an explanation of what had to be done and the time such activities would take, which made sense to me (as opposed to a random figure coming out of nowhere). Then, after having seen the problem in details, I was given an alternative approach that would require less parts to be bought as actually not adding any benefit. So, I had a great work done (my problem had initially been poorly addressed by some "big name" company after 5 plumbers coming), I saved money, I was educated, and even I can tell the difference of quality of work between what I got this time compared to what I got from other plumbers. I was so impressed I felt I had to pay more than I was billed.
There are many things that go wrong in a house and I am usually reluctant in getting them addressed as I am usually afraid of the cost and the risk of being conned. After this experience, I actually am thinking about some big change projects as I feel I have found someone I can trust.
