I was having new counter-tops put in and had purchased a sink and a new faucet. When it came time to have them connected I came on homestars and chose waterworks because they were the highest rated. I'm from Kingston originally so I didn't really know any companies in Toronto. I called on Monday or tuesday and they were able to come on a Friday which was perfect. The plumber arrived on time and seemed very knowledgeable. At first i was put off by the estimate of what it was going to cost me as it seemed high but after looking around on this site and others it looks like it was a fair price. Like I said, I didn't have a lot of experience with plumbers in Toronto. Its worth it to know that you're getting a professional to do the work and knowing that if anything goes wrong there is someone there to call who will back up their work. Others might have been cheaper but I think you take a risk when you play that game.
He completed the work very quickly and was quite friendly. It took only 2 hours to connect both the sink and faucet and he made sure that they both worked before he left.
