What’s the Cost to Unclog a Main Sewer Line in Michigan

Oct. 10, 2019
Stuck with a clogged sewer line?

If so, the first question on your mind is probably, “How much is it going to cost to unclog it?

In Michigan, the cost to unclog a main sewer line ranges from $99 to $2,000.

We know—that’s a pretty big price range. The price varies because of the following factors:
  • The severity of the clog
  • The distance of the clog
  • The number of clogs you have
Below, we’ll go into more detail about each of these factors. We’ll also share how to verify if you have a main sewer line clog.

Factors that determine the price to unclog a main sewer line

Let’s look at each of the factors we mentioned above in more detail.

Factor #1: The severity of the clog

Here's the bottom line: A severe clog will be more expensive to unclog than a standard clog because severe clogs require more time and specialized equipment.

If you have a standard clog, a plumber will likely be able to punch a hole through the clog using a plumber's snake or rod, which is the easiest and least expensive way to dislodge a clog.

However, severe clogs (often caused by an intruding tree root), require a plumber to use special equipment. Often the plumber will use hydro jetting, which involves shooting water at high pressure inside the clogged pipe. Since this equipment is expensive and requires more labor to operate, it will increase the overall cost.

Factor #2: The distance of the clog

Generally speaking, the farther the clog is from the sewer cleanout (the access point to your sewer line), the more expensive the service will be.

Why? The reason is simply because the farther away the clog is, the more effort it will require on the part of the plumber to break up the clog.

Factor #3: The number of clogs you have

Before the plumber even starts to unclog your sewer line, they will usually perform a camera inspection to pinpoint the clog’s exact location.

During this camera inspection, the plumber may find that you have multiple clogs, or multiple areas that are at risk of clogging in the near future.

If you have multiple clogs, the total cost of the project will be more expensive because it will require more time and labor from the plumber to break up all the clogs.

How to tell you have a main sewer line clog

Your home’s plumbing system consists of a main sewer line and several secondary lines that feed into the main line.

As a homeowner, you’ll want to know which of these lines is clogged because it’s typically more expensive to unclog a main line compared to a secondary line.

Here’s the difference between the 2 types of sewer lines:

The secondary lines transfer waste from plumbing fixtures (such as a toilet, bathtub or sink) to the main line. The main sewer line then carries this waste out of your home to the city sewer line.


Secondary plumbing lines feed into the main sewer line

You’ll know you have a clog in the main sewer line if you notice the following signs:
  1. Standing water in multiple locations: If you see water backed up in multiple sinks or tubs, that indicates your main line has a clog.
  2. Multiple sinks or tubs won’t drain: If you’ve noticed multiple fixtures that won’t seem to drain, that’s usually a sure-fire sign your main line is clogged.
  3. Gurgling noises: Loud gurgling sounds could indicate your main line is clogged or the flow of sewage is highly restricted.
  4. Bad odors: An unpleasant smell could indicate your sewer line is backed up.

If you notice any of the signs above, but only in one location or with one fixture, it's likely a secondary line that's clogged.

Either way, you should contact a plumber for assistance.
