Why the Camera Comes First

Why it is first and not second

Every decision about a sewer repair hangs on four facts: where the problem is, how long the line is, what the pipe is made of, and whether it still has its shape and slope. None of those can be learned from a backup, a wet lawn or a conversation. The camera learns all four in under an hour. A contractor who proposes a repair before running one is proposing a repair to a pipe he has not seen, and you would not accept that from a mechanic or a dentist. Do not accept it from a sewer crew.

How the equipment itself works, the self-leveling heads, the sondes and the locators, is covered on the lining site's camera page. This page is about what you, the buyer, should insist the inspection deliver.

What a recorded inspection must show

• The full length. From the cleanout or the point of entry all the way to the public main or the septic tank, not just to the first defect. A problem at 30 feet does not mean the pipe is sound at 60.
• Distances on screen. A running footage counter burned into the video, so that each defect has an address in feet from a known starting point. Without the counter, nobody can find the problem again, and nobody can check a bid's footage against the pipe.
• A level picture. A self-leveling head keeps the water at the bottom of the frame, which is how you tell a crack on top from a crack on the bottom, and how standing water reveals a sag. A spinning picture hides both.
• A surface locate with depth. At each defect, and at the connection to the main, the technician walks the yard with a locator, finds the camera head from above, marks the spot and reads the depth. Those marks are what turn a video into a plan: they decide where a pit goes, how deep the dig is, and whether the trouble is under your grass or the city's street.
• A pause at each problem. Long enough to see it clearly, with the technician's narration or a written note identifying what it is.
• Material and diameter. Noted at the start and wherever they change, since a line that starts cast iron and turns clay at the foundation wall is two problems, not one.

Own the footage

The recording belongs to you. You paid for it, it depicts your property, and it is the only evidence anyone will ever have of what the pipe looked like before work began. Ask for the full file, not a highlights clip, by link or on a drive, before the technician leaves. Keep it with the house records along with the written report.

Owning the footage is what makes competition possible. Hand the same video to two more contractors and ask each one to quote from it. They will see the same pipe and bid the same footage, and the differences that remain between their proposals will be real differences in method, warranty and price rather than differences in what each one imagined. Our bid checklist explains how to line those proposals up. A company that keeps the video or charges extra for a copy has made it harder for you to get another bid, and that is usually the point.

Reading the report

Some reports are a page of plain language; others, especially on commercial and municipal work, use the coding system that the trade associations publish for pipe condition. You do not need to memorize the codes, but the common ones translate easily.

• Crack or fracture. A line in the pipe wall. A crack is closed; a fracture has visibly separated. Fractures in several places along a run usually point toward lining or replacement rather than a spot fix.
• Offset joint. Two pipe sections no longer line up. A small offset catches debris; a large one lets soil in and makes lining harder, since the liner has to bridge the step.
• Root intrusion. Roots inside the pipe, which means an opening somewhere lets them in. Cutting the roots fixes the symptom for a season; the opening is the actual defect.
• Sag, belly or standing water. Water pooled in the pipe after the flow stops. The pipe has settled and lost slope. This matters enormously for method choice, because a liner takes the shape of what it is installed in.
• Deformed or collapsed. The pipe is no longer round, or is blocked. Lining is off the table for the deformed section.
• Scale, grease, debris. Buildup rather than damage. Cleaning fixes it, and the camera should go back in after cleaning to see what the buildup was hiding.
• Infiltration. Water entering the pipe from outside, often visible as a trickle at a joint. It indicates a defect even where the wall looks intact.

A report that lists defects without footage marks, or that gives a severity without describing what was seen, is not a report. Ask for the version with the numbers.

When a second camera run is warranted

One good recording is usually enough. Run a second one when the first did not reach the main, because of a blockage or because the technician stopped early; when the line was so dirty that the wall could not be seen, in which case clean first and then look again; when the recommended repair is a full replacement and you have not had an independent set of eyes on the video; when the footage was not given to you; or when a bidder's scope quotes a length that does not match the counter on your recording. A second run by an unrelated company is a small cost against a trench or a full-length liner, and it answers the question of whether the first contractor read the pipe or read the room.

Also expect a camera run after the work. The post-repair video, with the same footage counter, is the baseline the warranty rests on and the proof the connections were reinstated and the slope holds. It should be written into the bid.

Why there is no honest price without it

A sewer price has only a few ingredients: feet of pipe, diameter, depth, access, method, restoration and permits. Every one of those comes off the camera and the locate. Length and diameter come from the counter and the head. Depth comes from the locate. Access and restoration depend on where the defects are marked on the surface. Method depends on whether the pipe is round and sloped, which only the level picture shows. A contractor without the recording has none of those inputs and is quoting from what similar houses have cost. If the guess is high, you overpay. If it is low, the scope grows on the day of the work. Neither outcome is a price; both are a bet, and you are the one holding the stake.

So the order is fixed: camera, then footage in your hands, then a scope that cites the footage, then a number. Skip the first step and the rest cannot be trusted. The hiring guide walks through the steps that follow, and the red flags page covers the contractors who would rather you skipped this one. Your state page lists a verified contractor where one has been checked; where none is, the national line will find one who records every inspection and hands you the file.
