Sewer repair in Calgary
Something downstairs is wrong. The floor drain is wet and nothing was running. The basement toilet burps when the washing machine drains upstairs. There is a smell in the utility room that was not there last week, or a patch of lawn that is green and soft in a season when nothing should be. One of those is what brought you here, and the phrase you typed was the most obvious one available, which is usually the right instinct.
We are a Calgary trenchless company. We do one thing before we quote anything: a camera goes down the line and you see what it sees. No method gets named on the phone, because the three facts that decide this job — what the pipe is made of, where it has actually failed, and what is buried alongside it — are all invisible until somebody looks. A quote given without footage is a guess with a number attached to it.
We dispatch around the clock and a person answers. Most of what follows on this page is about what happens after that call, in the order you will actually meet it. Read the verdict table first if you are short of time: two of the five outcomes on it are not repairs at all, and on the newer side of this city those two are the common ones.
What happens next
Your decisions, in the order you actually meet them.
- 1
Decide whether this is tonight or tomorrow
Sewage coming up through a floor drain or a shower is a stop-everything call and it belongs on the emergency page, which covers what to shut off and what to leave alone. A drain that is slow, gurgling, or backing up only under load is genuinely a morning problem. The difference matters because the second one buys you the time to get the line looked at properly instead of buying whatever is available at midnight.

Get the line looked at before anyone quotes it
This is the step people skip, and it is the one that costs the most to skip. A camera run with a locate puts a depth and a position in the yard against the defect. Until that exists, every number you are given is priced against a guess, and the guesses are not conservative in your favour. If a contractor will quote a replacement over the phone, that is information about the contractor.

Watch the footage, and ask to be shown the good pipe
Anyone can point a camera at a root ball. The question that separates a diagnosis from a sales call is what the rest of the line looks like: how much of the run is sound, whether the defects repeat at a regular spacing or sit in one place, and whether the camera got all the way to the connection or stopped short. Ask to see the parts where nothing is wrong. What is absent from a video tour is usually the answer.

Find out where the defect sits relative to the property line
A defect out near the street and a defect under the front step are the same repair technically and a completely different conversation about who pays for it. Confirm with the City of Calgary who owns the section that failed before you agree to any scope that crosses the property line. We will show you on the footage exactly where the defect sits. We will not tell you whose section it is in, because we do not have that on paper and will not invent it.

Take the scope in writing, against the footage
The scope should name the run it covers, the point it starts and stops at, the method, and what happens to the surface that gets opened. Reinstatement is frequently the largest part of a dug job and the easiest thing to leave vague. If the scope and the video disagree about how much of the line is being touched, the video is the one that is right.
What the camera comes back with, and what it means
| On the footage | What that is | What it routes to |
|---|---|---|
| The lateral is fine. The problem is inside the house. | A partly blocked branch, a failed fixture, or a vent problem producing exactly the gurgle and slow drain that a failing line produces. The camera goes out to the connection and comes back with nothing to report. | Not a sewer repair. We will say so, put the footage in your hands, and you will owe us for an inspection and nothing else. This outcome is more common than the internet suggests. |
| Long clean plastic pipe with one blockage sitting in it. Long clean runs. A defect in PVC is usually one identifiable event at one location, not a line-wide condition. | The pipe is doing its job. Something is in the way of it — grease, wipes, sediment, a root that found one badly seated joint. This is what a service call in a post-1980s Calgary community usually turns out to be. | A cleaning, not a replacement. Where the camera shows PVC and a single blockage, the answer is usually a cleaning rather than a replacement. If the same blockage returns in the same place, that is when the camera goes back down and the conversation changes. |
| Roots entering at regular intervals, with sound pipe between them. Root masses entering at regular intervals, matching the joint spacing. Offset joints showing a step in the pipe wall. Often a long run of sound pipe between two bad joints. | The pipe barrel is intact and the joints are not. This is the classic inner-city Calgary finding and it is the one case where the trenchless options are genuinely competing with each other rather than with a shovel. | Either a liner or a replacement, and the camera picks. A structurally sound but leaking pipe — the classic case being clay with root intrusion at the joints and good pipe in between. A line that is failing along its whole length, or one too deformed or collapsed to line. One bad joint in an otherwise sound line is a smaller job again: One crack, one offset joint, or one root intrusion in an otherwise sound line. |
| Standing water sitting in a low spot with sound wall either side of it. Standing water sitting in a low spot with the pipe wall sound either side of it. Clean pipe with one specific defect, rather than a line failing all over. | A belly. The bedding under a section of pipe settled and now the line holds water where it should be draining. Nothing is broken, and that is exactly what makes it awkward — there is no defect to patch. | Not a cleaning and not a lining job. A bellied ABS line is the clearest case there is of lining being the wrong answer: a liner follows the host, so it will faithfully reproduce the belly and the water will still sit in the same low spot afterwards. That is a bursting or a dig job. The honest options are a replacement of the affected length or leaving it alone and managing it, and which of those is right depends on how much it is actually costing you. |
| An oval or deformed bore, a blistered wall, or a camera that cannot pass at all. An unmistakable oval or egg-shaped bore. Blistering and peeling of the inner wall. Often the camera simply cannot pass. | The pipe has lost its shape or lost its integrity. In Calgary this is most often clay that has offset badly, cast iron that has corroded through along the bottom, or a material that was never going to last as long as the house. | A replacement, and the method is largely decided for you. A line that is failing along its whole length, or one too deformed or collapsed to line. A dig is the alternative and is sometimes the cheaper one — the full comparison is its own page. |
Which Calgary you are standing in changes the likely answer
This city is effectively two markets for buried pipe, and the line between them is roughly the age of the neighbourhood. Inside the older rings the lateral is commonly vitrified clay — commonly found in homes built before roughly the 1960s, and in some areas later than that — and it is jointed every few feet under one of the healthiest mature elm populations anywhere. Those lines genuinely fail, and they fail in a way that trenchless methods are unusually well suited to fixing.
Out in the communities built from the 1980s onward the same house has PVC or ABS in long runs with very little for a root to enter. Where the camera shows PVC and a single blockage, the answer is usually a cleaning rather than a replacement. Plastic of this age has not run out of service life, and what has gone wrong is almost always one identifiable event rather than the pipe giving up. That is not a modest thing to publish on a page selling sewer repair. It is the reason the recommendation is worth anything when the footage does show a finished line.
Cast iron sits in between and is the one that most often surprises people, because it can look sound from above while the invert has gone. Lining works only if enough sound wall remains to carry the liner while it cures, and heavy channelling can mean there is not. Descaling first is often required, and sometimes descaling is what reveals the pipe is past lining.
The lot decides more than the method does
An inner-city lot with lane access, a narrow side yard and a garage at the back constrains what equipment can physically reach both ends of the run. That is not a reason to dig instead — it is frequently the reason not to — but it does decide where the access pits can go, and on some lots it decides that one of them lands somewhere inconvenient. We work that out on the first visit rather than on the morning of the job.
What is sitting on top of the line is the other half of it. A driveway, a patio, a mature tree or a finished yard is where trenchless pays for itself, because the reinstatement on a dug line is routinely the larger half of the bill. A short shallow run across bare ground with nothing on it is the opposite case, and we will tell you so.
A water main break is not your sewer line
Calgary has spent recent winters with municipal water main breaks in the news, and the vocabulary has leaked into how people describe problems at home. They are different pipes doing different jobs. A sanitary lateral carries waste away from the house under gravity; a water service brings pressurised drinking water in. A failure in one does not look, smell or behave like a failure in the other, and they are not repaired the same way.
If what you actually have is a wet patch in the yard with no drain symptoms at all, or a drop in pressure at every tap in the house, that is a water line conversation and it has its own pages. Worth sorting out before booking anything, because the wrong specialist will still turn up.
The authority, and the season
The authority having jurisdiction in the city is the City of Calgary, and in the surrounding municipalities it is that town. Locates go through Alberta One-Call before anything is opened, and that has to come back clear. We do not set that schedule and will not pretend to a timeline we do not control.
Work happens year-round here and the ground being frozen changes the day rather than cancelling it. What winter genuinely changes is access, spoil handling and reinstatement, because ground that comes out in winter goes back in differently and a lawn opened in February does not look settled until spring. If the failure can safely wait for better ground, that is a legitimate thing to ask us and we will give you a straight answer.
When not to call us
Do not call us if the fixture is the problem. A single slow sink, a toilet that runs, a tub that drains badly while everything else in the house is fine — those are inside-the-house jobs and a general plumber is the right and cheaper call. Do not call us for a first blockage on a plastic line in a newer community either, at least not for a replacement conversation: get it cleared, and if it comes back in the same place, then the camera is worth paying for. And if somebody has already put a camera down your line and given you footage, bring the footage. We would rather read it and tell you the last verdict was right than sell you a second inspection to confirm it.
Questions about sewer repair in Calgary
How quickly can you get someone out for a sewer repair in Calgary?
We dispatch around the clock and a person answers the phone, including at three in the morning. Inspection and clearing work can usually start as soon as we are there. Anything that involves opening ground waits on Alberta One-Call locates coming back clear, and that is not a schedule we control or will promise on.
Do you have to dig up my yard to repair a sewer line?
Usually not the length of it. Most of this work is done from small access pits at each end of the run, or through an existing cleanout, so the driveway, the trees and the lawn between the pits are left alone. It is not excavation-free — the pits are real holes — but the trench is what costs, and the trench is what goes away.
Will you quote a sewer repair over the phone?
No. We will tell you on the phone what the likely range of outcomes is for a house of that age in that part of the city, and that is genuinely useful. We will not attach a number to it, because the material, the defect location and what else is buried near the line are all invisible until the camera has been down.
Can sewer lines be repaired in winter in Calgary?
Yes, and they are, every winter. Frozen ground makes the excavation and the reinstatement harder rather than impossible. What it changes most is what the surface looks like afterwards: ground opened in the cold settles differently and a lawn will not look finished until the following spring.
Do you work outside Calgary?
Yes — Airdrie, Cochrane, Okotoks, Chestermere and High River. The pipe and the methods are the same; what changes is the authority having jurisdiction, and outside the city the runs are often longer, which matters to how a job is laid out.
My drain backed up once. Does that mean the line is broken?
Not on its own. A single backup on a plastic line in a newer Calgary community is almost always a blockage, and the correct response is to clear it rather than to camera it. A backup that repeats in the same place, or one on an older clay line, is the one worth looking at properly.
Footage first, quote second
You watch the screen, you keep the recording, and you are free to take it to somebody else. That is the point of doing it in that order.
