Unhappy in Saint Albert

So, you call EZ Plumber thinking they sound reputable, but you get some other plumber. Why do plumbing companies do this? Yes, they fixed the problem, but $625 for 1 hr! Are we paying for the plumber and a referral fee as well? If the City can send a crew and clean the line for $340 then $625 seems excessive. If you call one plumbing company and get another you should be told they use subcontractors.
