I have had an awful experience with these guys. I had pipes vibrating in my century old income property in cabbagetown - I feared pipes might burst so I called ermerg number in the evening - they came at 3 am and said it was not a plumbing problem - and they charged me 400$ - I have had hydro and an electrician take a look and both say it is plumbing - now plumber.ca wont take my calls - I used my wife's phone to reach them and they keep promising to send a tech out - they are not reputable - I am contacting ellen roseman at the star to expose them
