Déblocage Montréal

We are drain specialists, fully insured and bonded. For years we have worked as plumbers, but recently gave up the glamour of plumbing to focus our efforts on one aspect: drains.

Cassidy & Cassidy
About Us

Mike and Sean Cassidy, father and son, have not only spent many years working in the drain unblocking business, but have over 50 years of combined experience in customer service. Realizing however, that this industry, as with many others, left a lot to be desired with regards to customer service, they branched out on their own last year and built Cassidy & Cassidy Déblocage/Unblocking.

This is a family-run business that has put everything on the line to bring back the level of customer service that today, sadly, has been largely lost and missed by many.

That being said, Cassidy & Cassidy not only brings expertise and state-of-the-art equipment to the table, they stand out because of the gold-standard level of customer service that they provide with each and every service call. This is a company that does uniquely stand out, at a time when honesty, integrity, dedication and respect for the customer is so hard to find.

Should I have my drains checked?
  • I’m selling my house. Why not let the purchaser incur the expense of inspecting my pipes?
  • If my main sewer is blocked will the city pay some or all of the bill?
  • What is a back-water valve and how can I tell if I have one?
  • Is there any advantage of using a pressure machine over a rotor rooter-type machine?

Our Services
Montreal Drain Unblocking | Cassidy & Cassidy Déblocage
We offer camera inspection of main drains, when people are buying or selling a house.

We can locate pipes before renovations are being done. We are locating backwater valves, as this has become a requirement in some municipalities, as well as locating main cleanout access points. We have also used camera technology to locate air ducts that have either not been installed properly or have become disconnected.

We offer maintenance contracts in areas where drainage systems are more prone to blocking.

For example, iron ochre, oil and grease for restaurants, industrial chemicals, apartment and condo buildings, hospitals and centre d’accueils. We also offer maintenance contracts for French drains.

Although some municipalities are no longer responsible for blockages on what used to be considered their side of the sewage line, many municipalities still assume that responsibility.

Therefore, it is in the homeowner’s best interest to determine exactly where the blockage is. Often this can save them hundreds, perhaps thousands of dollars.
