How long does a hydro-jet cleaning last on a Calgary sewer?

How long hydro-jetting holds up depends more on your pipe's condition and what caused the blockage than on the cleaning method itself. There is no standard answer: a sound line with a one-off grease blockage can stay clear for a long time, while a line with root intrusion, offset joints or deteriorating walls will need attention again, however well the jetting went.

What actually determines the result

Grease and soap buildup in a kitchen line can return faster than roots in a clay sewer, because cooking habits do not change. Roots are persistent: they re-enter through the same crack or joint that let them in the first time, and jetting cuts them back without sealing the opening. If the line has a belly (a low spot where water pools), debris will collect there again no matter how clean the rest of the pipe is.

This is why a camera inspection before or after jetting matters so much. Hydro-jetting costs roughly $400 to $800 for a main line in Calgary; adding a camera inspection runs about $200 to $600. Spending that extra amount tells you whether the pipe has cracks, root entry points or a belly that will shorten the result, and whether a spot repair or lining is worth considering before the problem comes back.

Never agree to a sewer replacement without seeing the camera footage yourself. A reputable plumber will show you the recording and explain what they found.

What a fair quote for this work includes

Ask for a fixed price that covers the jetting, the camera inspection (before and after, ideally), removal of the debris, and a written report on the pipe's condition. The quote should state whether the price changes if the technician finds roots or a collapsed section mid-job, and what the warranty covers if the line backs up again within a defined period. Get the warranty terms in writing and compare them across quotes, because there is no industry-standard length.

Permits and who does the work

Drain cleaning and hydro-jetting do not alter the plumbing system, so they do not require a plumbing permit under the Alberta Permit Regulation or the City of Calgary's rules. The work should still be done by a certified journeyperson plumber or a registered apprentice working under one, as plumbing is a compulsory certification trade in Alberta under the Skilled Trades and Apprenticeship Education Act. Ask to see the plumber's trade certificate before the work starts, confirm the contractor holds an Alberta prepaid contracting licence if you are paying any deposit before the job is complete, and request a WCB-Alberta clearance letter; WCB-Alberta says anyone who hires a contractor without coverage could be responsible for unpaid premiums.

Before you book, ask the plumber directly whether a camera inspection is included, what the report will show, and whether the condition of your pipe changes the scope or the price.
