I've used Capital Plumbing & Heating once before, but it had been a long time. I had a tennant without hot water so I called them up for help. Darren came out and he was very punctual and easy to deal with. He told me the issue, and it turns out the hot water valve was partially closed. So, the issue was minuscule and he was able to take care of it nice and quick. I'd definitely use them again.
