When you call most drain companies with a backed-up main sewer line, here is what typically happens: a technician shows up with a cable machine, runs a three or four-inch blade down the line, cuts through the blockage, confirms flow is restored, and leaves. The call takes thirty to sixty minutes. You pay the invoice. The water drains.

That’s the standard. And for a lot of companies, that’s the entire service model — quick, repeatable, and deliberately incomplete.

The business case for not fixing it

A drain company that clears your line and sends you on your way has created a customer who will call again. If the root cause is never addressed — the cracked joint letting roots in, the grease buildup coating the pipe wall, the belly where waste accumulates — the line will back up again. Maybe in six months. Maybe in a year. But it will back up again.

That repeat call is revenue. The company gets paid the same rate to clear the same line a second time. And a third time. The customer keeps calling because the problem keeps recurring. The company keeps coming because the call keeps coming.

This isn’t necessarily intentional. Many companies simply operate the way the industry has always operated — fast clearings, no diagnostics, move to the next call. But the effect on the homeowner is the same regardless of intent: you spend more money over time on a problem that was never actually solved.

“A company that clears your line without a camera has no idea what’s actually in it. Neither do you.”

What a blade through the line does and doesn’t do

A cable machine with a cutting blade is effective at restoring flow. Put the right blade on the right cable, run it through the blockage, and water moves again. That part of the service works.

What it doesn’t do is clean the pipe wall. A three or four-inch blade cuts a path through the centre of the blockage. The buildup coating the pipe walls — grease, scale, compacted debris — stays. The roots that were cut are still rooted in the pipe joints. The crack that allowed them in is still open. Flow is restored but the pipe is in the same condition it was before the service, minus the specific blockage that caused the backup.

This is an important distinction. Flow restoration and pipe restoration are not the same thing. Most standard drain services deliver the first one. They do not address the second.

No camera means no diagnosis

The most revealing part of the standard service model is what doesn’t happen at the end: there is no camera inspection. The technician confirms that water flows, packs up the equipment, and leaves. Nobody looks at what’s in the pipe. Nobody documents the condition. Nobody tells you whether the line has a structural problem that will cause the next backup, or whether it’s in reasonable shape and just needed a routine clearing.

That information gap is where homeowners get stuck. Without a camera, there is no way to know whether the right next step is annual maintenance, a more thorough restoration, or a structural repair. Every decision is made blind — by the technician and by you.

A camera inspection after clearing takes an additional fifteen to twenty minutes. It produces a documented record of the pipe’s condition. It tells you what caused the backup, what the pipe looks like now, and what the realistic outlook is. That information changes the conversation entirely. Instead of “we cleared it, call us when it backs up again,” it becomes “here is what is in your line, here is what caused this, and here is what we recommend.”

What a different standard looks like

Imperial was built specifically because this standard was not good enough. The approach here is different in a few specific ways.

First, a diagnostic assessment before the service determines which approach is right for the line. Not every line needs the same thing. A line with a simple grease blockage and no structural issues needs a different service than a line with years of root intrusion and compacted buildup. Treating them the same way produces inconsistent results.

Second, camera inspection is included in the Imperial Standard and Imperial Restoration tiers — not as an upsell, as part of the service. You see what is in the line. You receive a written report. The findings are documented before you leave the conversation.

Third, the recommendation is based on what the camera actually shows — not on what produces the most repeat calls. If the line is in reasonable condition and just needs annual maintenance, that is what we recommend. If it needs a full restoration or a referral for structural repair, we say that too.

The goal is a customer who understands their line’s condition and can make an informed decision — not one who calls back every six months because nobody ever told them what was actually wrong.

What to ask the next time you call

Before booking any main sewer line service, ask these two questions: Does the service include a camera inspection after clearing? And will I receive a written report of the findings?

If the answer to both is yes, you are dealing with a company that is interested in diagnosing your line. If the answer is no or vague, you are likely getting a blade through the centre and an invoice — and you will probably be calling again.
