A sewer scope on a typical house with an accessible cleanout usually takes about 45 to 90 minutes on site, covering set-up, the camera run to the main, locating defects, a walk-through of findings and clean-up. A toilet pull, a backed-up line, cleaning before the camera, several branches or a camera that stops early add time. The video is often handed over the same day; a written report can take one to several days.
- The camera run itself is often the shortest part of the visit; access, locating and explaining findings take most of the time.
- A toilet pull, a seized cleanout plug or a backed-up line can double the time on site or turn one visit into two.
- Book the scope the day an offer is accepted; spring and early summer are the busiest weeks for drain companies.
- Ask before booking when the video and the written report will arrive, because the report is what a condition deadline needs.
- Clear access, no water use and a short history from you are the three things that make the visit faster.
01 /How long does a sewer camera inspection take on site?
A sewer camera inspection on a house with an open, reachable cleanout commonly takes 45 to 90 minutes from arrival to departure. The camera push to the main may only take ten to twenty minutes of that. The rest is arrival questions, opening the access, stopping at each observation, finding the camera head from the surface, marking defects, walking you through the video and resealing everything.
| Stage | Typical time | What happens |
|---|---|---|
| Arrival and history | 5 to 10 minutes | Questions about symptoms, backups, past cleaning and the purpose of the scope |
| Opening the access | 5 minutes for a cleanout; 20 to 40 minutes if a toilet must be pulled and reset | Plug loosened slowly; toilet removed and the flange plugged |
| Camera run to the main | 10 to 30 minutes | Steady push with pauses at joints, transitions and every observation |
| Locating and marking | 10 to 20 minutes | Sonde found from above at defects and the end of the run; marks and depth recorded |
| Review with you | 10 to 15 minutes | Replay of key frames, plain explanation, questions |
| Clean-up and resealing | 5 to 10 minutes | Cable cleaned, plug reinstalled or toilet reset, video file handed over |
Two houses on the same street can take very different times. A 1990s house with an exterior cleanout and a short PVC lateral may be finished in under an hour. A 1940s house with a seized plug, a clay lateral full of roots and a long run to a lane main can take the better part of a morning.
02 /What makes a sewer inspection take longer?
A sewer inspection takes longer when access is hard, the line is not flowing, the pipe has several branches, or the camera cannot get through on the first attempt. The table shows the common causes and roughly how much they add, so you can plan the day around them.
| Situation | Typical effect on the visit | Why |
|---|---|---|
| No usable cleanout | Adds 20 to 40 minutes | Toilet removal, flange plugging, reset with a new seal and test flush |
| Seized cleanout plug | Adds time or forces a toilet pull | Old brass plugs in cast iron often will not turn without risking the fitting |
| Line backed up | Clearing first, often an extra hour or a second visit | A camera cannot inspect a pipe full of standing wastewater |
| Heavy roots or grease hide the wall | Cleaning plus a second camera pass | The pipe beneath has to be seen before judging it |
| Several branches to inspect | Adds 15 to 30 minutes per branch | Each run is entered, recorded and located separately |
| Camera stops before the main | A second access point, or a return visit | Obstruction, collapse or a deep sag blocks the head |
| Winter conditions | Adds time to locating | Snow over the route, stakes instead of paint, cold equipment |
| Occupied multi-unit building | Scheduling and access add hours | Residents must stop water use; mechanical rooms need keys |
03 /How far ahead do you need to book a sewer scope?
Book a sewer scope as soon as you know you need one. In many Canadian cities a scheduled residential scope can be booked within a few days, but spring thaw, early summer storm season and the busiest weeks of the resale market fill calendars quickly. Emergency backups take priority over routine inspections, which can push scheduled work back at short notice.
- Gather the basics before calling
Address, approximate year built, purpose (purchase, backup, renovation, routine), any known cleanout, and your deadline.
- Call two or three providers
Ask for their earliest date, what the price includes, and when the video and report are delivered. The guide to choosing an inspection company lists the questions to ask.
- Confirm access in writing
For a house you are buying, your agent arranges access with the seller and confirms whether a toilet can be pulled.
- Book the same day as the home inspection if you can
One appointment at the seller's house, and each inspector can flag clues for the other.
- Hold a back-up slot
If the first visit reveals a blocked line, a second visit after cleaning has to fit before your deadline.
04 /When will you get the video and the written report?
The video is often available on the day, either on a USB drive left with you or as a download link. The written report varies more: some operators produce a short summary on site, others send a formatted report with stills, distances and a sketch within one to three business days, and a coded report for a larger building can take longer.
| Deliverable | Typical turnaround | What to ask |
|---|---|---|
| Raw video file | Same day | What format, and does it play on an ordinary computer? |
| On-site summary or verbal walk-through | Same day | Can you note distances for anything significant before you leave? |
| Written report with distances and stills | Same day to a few business days | Will it arrive before my condition deadline? |
| Surface locate marks | Made on the visit | Can you photograph the marks and add measurements to the report? |
| Coded report for a building or long run | Several business days or more | Is coding included in the price, and when is it due? |
Whatever the turnaround, check the report against the report checklist the day it arrives. Missing distances or locates are much easier to add while the job is fresh.
05 /How should a buyer budget time inside a condition period?
A buyer should plan the sewer scope as a three-part sequence, not a single appointment: the scope, a quote or second opinion if anything significant turns up, and the negotiation. Condition periods in Canadian resale purchases are often short, so each part needs room. The example below assumes a typical inspection window; yours is set by your contract.
| Day | Task | If it slips |
|---|---|---|
| Day 0 | Offer accepted; call sewer inspection companies | Every later step compresses |
| Day 1 to 2 | Home inspection and sewer scope, same visit if possible | Ask for the earliest slot with any provider that delivers video the same day |
| Day 2 to 3 | Video reviewed; repair quote or second opinion requested if needed | Send the video to a second company rather than waiting for another visit |
| Day 3 to 4 | Decide: proceed, ask for a price change or credit, or walk away | Your agent or lawyer may seek an extension; do not assume one |
If the camera stops early and the line needs cleaning before it can be judged, that alone can use two days. It is one reason to book the moment the offer is accepted. The wider decision is covered in should you scope before buying.
06 /How can you make the inspection faster and more useful?
You make the inspection faster by clearing the way to the access point, stopping water use, and telling the operator what you already know. Each of these saves minutes on site and makes the result more reliable.
- Clear storage boxes, laundry and furniture away from the cleanout and the stack, and leave a light on in the basement.
- If a toilet will need to come off, empty the vanity area around it and remove bath mats.
- Ask everyone in the house not to flush, shower, run the dishwasher or start laundry during the visit.
- Keep pets away from the work area and the open front door.
- In winter, clear snow along the likely route from the house to the street so locate marks can be made.
- Have your lot survey or real property report handy so the operator can relate distances to the property line.
- Write down the symptoms, dates of any backups and past cleaning invoices before the operator arrives.
Being there helps too. You can see problem spots live, ask for a pause or a second look, and confirm that the marks on the lawn match what you saw on the monitor. When you are ready, request an inspection quote and mention your deadline.
FAQQuestions people ask
Can a sewer scope be done on the same day as the home inspection?
Often, yes. Some home inspection companies offer the scope themselves, and others coordinate with a drain company. One visit to the seller's home saves time for everyone.
Why did my sewer inspection take three hours?
Common reasons are no usable cleanout, a seized plug, a backed-up line that had to be cleared first, roots that needed cutting before a second camera pass, or several branches inspected separately.
How long does a sewer scope take for a condo building?
A building survey usually takes a half-day or more, because there are several runs, larger pipes, access to arrange and residents who must limit water use. A single townhouse lateral can be similar to a house.
Do I need to be home for the whole sewer inspection?
It is not essential, but being there for the camera run and the review is the best way to understand the findings and ask questions while the operator is on site.
How long does it take to get sewer scope results?
The video is usually available the same day. A written report can come the same day or within a few business days; ask before booking if you have a deadline.
Does winter make a sewer scope take longer?
The camera run is similar, but locating and marking take longer in snow, and a seized exterior cleanout cap is harder to deal with in the cold.
