After a bad sewer scope, a Calgary buyer should confirm the finding from the full video, locate it and check which side of the property line it sits on, get a written repair or replacement quote, and then decide before the condition deadline: waive and budget, ask for cleaning, a repair before closing, a credit or price reduction, a holdback, or let the condition lapse and walk away.
- A bad result is a negotiating position only while the condition is open; once waived, the line is yours.
- Location decides the next call: a City-side defect goes to 311, a private-side defect goes to a contractor for a quote.
- A written quote turns a scary video into a number the seller can respond to.
- If time runs short, ask your Realtor about a written extension before the deadline, not after.
- Walking away is a legitimate outcome; if the condition is not waived by the deadline, the offer becomes void.
01 /What counts as a bad sewer scope?
A bad sewer scope is one that finds something a buyer would have to pay to fix, or that leaves part of the line unseen. That ranges from roots at a single joint in otherwise sound pipe, which may mean nothing more than a cleaning schedule, to a collapsed or flattened section that means replacement. Most results sit in between: an offset, a sag holding water, cracks in clay, scale in cast iron.
| Finding | Usual seriousness | Typical path |
|---|---|---|
| Roots at one or two joints, pipe sound | Low to moderate | Clean; plan lining later |
| Single offset or crack | Moderate | Spot repair quote |
| Sag holding water over a short stretch | Moderate | Monitor or excavate the low section |
| Heavy scale or channelling in cast iron | Moderate to high | Descale and line, or replace the run |
| Many defects along the run | High | Lining or replacement quote |
| Collapse, deformation, fibre pipe flattening | High | Replacement quote |
| Camera could not finish the run | Unknown | Clear and re-scope before deciding |

02 /What should a buyer do in the first 24 hours?
- Get the full video and report
Not a clip. Check where the camera stopped and whether it reached the City main.
- Make sure the defect is located
You need a surface mark and depth. If the visit was camera-only, ask for a locate before the deadline.
- Check which side of the line it is on
Measure from the foundation to the mark and compare with the Real Property Report; see city vs. private.
- Tell your Realtor
Share the findings and agree who will contact contractors and when the listing side hears about it.
- Book a quote
Send the video and marks to at least one contractor for a written quote.
Resist two reflexes in these first hours. One is to forward a frightening still image to the listing side before you have a quote; it starts the negotiation without a number. The other is to assume the worst finding means the worst repair. A single offset can look alarming on screen and still be a modest spot repair once it is located and priced.
Run the numbers against the calendar. The Condition Deadline Scope Planner assumes two business days for this stage; if the finding is complex, that may not be enough, and the time to raise an extension is now.
03 /What if the defect is on the City side?
If the defect is on the City side, the City owns that section of pipe, from the main to the property line. Call 311, describe the finding and its measured position, and ask what the City needs to assess it. Keep the video and photos of the mark ready. The City decides whether and when it acts, so do not assume a date, and consider whether an unrepaired City-side defect affects your decision anyway.
A defect at or across the property line needs the boundary confirmed first. Until it is, treat the cost as possibly yours. Who pays sets out the split and the grey areas.
04 /What are the options for a private-side defect?
For a private-side defect, the options run from accepting it to walking away, and the right one depends on the size of the quote, the market and the seller. Each is set out below; the terms of any arrangement belong with your Realtor and lawyer.
| Option | When it fits | What you need |
|---|---|---|
| Waive and budget | Minor finding, or a price already reflecting it | The quote, so the budget is real |
| Ask for professional cleaning before possession | Roots in otherwise sound pipe | Video of the roots; a post-cleaning camera run |
| Seller repairs before closing | Isolated, well-defined defect | Agreed scope of work, invoice, post-repair video |
| Credit or price reduction | Seller prefers not to manage the work | Written quote supporting the amount |
| Holdback | Work cannot finish before closing | Terms set by the lawyers |
| Walk away | Replacement needed and seller will not move | Let the condition lapse, or act as your contract provides |

05 /How do I get a quote fast enough?
Get a quote fast by making it easy to give. Send the contractor the full video, the report, photos of the marks with measurements, the depth estimates and what covers the ground at each mark. Ask for a written quote that names the method, the length, the surface restoration, permits and any City-side work, and says what happens if conditions underground differ.
- Ask for the method and why. Lining, bursting, spot repair and open cut suit different defects.
- Ask what is excluded. Landscaping, driveway repair and basement floor work are often extras.
- Ask about timing. A seller-funded repair before closing needs a date that fits possession.
- Consider a second quote for anything large, especially if the first comes from the company that did the scope.
06 /What if the deal goes ahead with a known problem?
If the deal goes ahead with a known problem, plan the work and the insurance before possession. Book the repair or cleaning, confirm any holdback conditions with your lawyer, and ask your insurer about sewer backup coverage. The Insurance Bureau of Canada says basement water damage from a sewer backup is covered only with optional sewer backup coverage, and a known defect may affect what an insurer offers.
Keep the scope video, the quotes and the invoices together. After any repair, a follow-up camera run shows the work was done and gives a new baseline. If a backwater valve is part of the plan, the City recommends one on below-grade fixtures to reduce backup damage.
The scope does its job when it gives you a choice; the choice is only yours until the condition is waived.

FAQQuestions people ask
What should I do if my sewer scope fails before I go firm?
Get the full video, make sure the defect is located, check which side of the property line it is on, get a written quote, and decide with your Realtor and lawyer before the deadline.
Can I back out of a Calgary purchase because of a bad sewer scope?
If you have an unwaived sewer or inspection condition, not waiving it by the deadline means the offer becomes void. Confirm how your specific contract works with your Realtor and lawyer.
What amount should a buyer request from the seller after a failed sewer scope?
Base it on a written contractor's quote for the repair the footage supports. A number backed by a quote is far easier for a seller to accept than an estimate.
Should I get a second opinion on a bad sewer scope?
For a large repair, often yes. Another contractor or inspector can review the same video and quote independently, which also checks the first recommendation.
Does the City fix sewer defects found during a home purchase?
Only on the section it owns, from the main to the property line. Report a City-side finding through 311 with the evidence; the City decides whether and when to act.
