The toilets in my home were leaking. Based on the reviews from Homestars, I called Drainworks. The plumber that came to my home suggested that they all needed to be replaced - that fixing them would not be a good solution longterm. I went along with his suggestion, not really knowing any better. The cost was quite sustantial - over $300 for each toilet. Furthermore, as he was fixing them, he tired to add on more cost by telling me that now the supply valve needed to be changed and he could not warranty the service if there was to be a leak. He told me that I leak could be so severe that it could damage my downstairs ceiling. I felt that he was just trying to get more money from me. Needless to say, after such an expensive repair job, I will not be using their service again.
