What Does It Cost to Clear a Clogged Drain?

If a sink won’t drain, a tub is full of standing water, or more than one fixture is backing up at once, one of your first questions is probably: “How much will it cost to clear this?”

There isn’t one price that fits every house. In Kalispell and throughout the Flathead Valley, two homeowners can have the same clogged kitchen sink and still have very different jobs in front of them.

That’s because the work depends on the line, the house, and where the blockage sits.

Here are the five biggest things that affect the cost.

1. One Drain, or the Whole House

A single fixture line serves one part of the house: one kitchen sink, one bathroom, one tub. When that line blocks, that part of the house stops working and the rest usually carries on.

A mainline is the line between your house and the sewer or the septic. Everything drains into it. When it blocks, nothing upstream has anywhere to go, so the trouble often shows up in more than one place at once.

If more than one drain is backing up, tell us that when you call. That is one of the most useful things you can say before anyone reaches the house.

2. The Size of Your House

A smaller house has less pipe in it. Less pipe usually means less time finding the clog, and less time clearing it once it has been found.

A bigger house simply gives a blockage more places to be. The same slow sink can be a longer job in one house than in another.

3. The Size of the Line

The line under a bathroom sink and the line your whole house drains into are not the same size. Pipe diameter is its own factor, separate from how much pipe the house has and separate from whether the blockage is in one fixture or in the mainline.

You are not expected to know the diameter. If you know whether this is one fixture or several, that is enough to start.

4. The Age of Your House

What age really tells you is what is likely to be in the ground underneath.

Many homes around Kalispell were plumbed decades ago. Original drain lines in this valley are often near the end of their life rather than simply blocked. Age on its own does not mean a line has failed. It does mean what the pipe is made of matters more.

5. What Your Pipe Is Made Of

Drain lines in this valley can be galvanized, cast iron, PVC, ABS, Orangeburg, or terracotta clay. Most homeowners have no idea which of those is under the house. You are not expected to know, and it is not the kind of thing you can tell by looking at a sink.

Different materials last different lengths of time, and an older material can change how carefully a line should be cleared. That is a judgment made at the house, not something to guess from a photo of a faucet.

Same sink. Different house. Different job. One homeowner may have a kitchen line in a newer house on city sewer. Another may have the same slow sink in an older house, on a longer run, with a line that has clogged before. It is normal for those two calls to be different jobs.

Why a clog that comes back is a different conversation. A line that blocked once is one kind of visit. A line that blocks again a month after it was cleared is another.

In older Kalispell neighborhoods, tree roots can get into underground sewer lines. A line roots have found, tends to block again and again rather than stay clear. Grease, hair, wipes, and food scraps are the other common causes, and those start inside the house. Two of them you can keep out yourself: put grease in a sealed container in the trash, and fit inexpensive screens over the drains that catch hair.

The rest is on our page about common causes of clogged drains.

When clearing turns into something else. At some point a line stops being something to clear and becomes something to repair or replace. Where that point falls is a judgment made at your house. We will tell you what we are seeing before that conversation goes any further. There is a separate page on when to replace your home’s plumbing pipes.

What about a camera? A camera inspection is a service of its own. On a sewer-line clog, a camera can be the way to see what is actually in the line. Whether one is worth having depends on your line, not on a rule we can give you before we know what you are dealing with.

If water is where water shouldn’t be. Cost is not the first question when a drain is backing up into the house. Whether it can wait is. When to call a plumber covers the problems that need a plumber, and how soon. Read that one first if there is water where water should not be.

What should you have ready when you call? You don’t need to know everything about your drains. Just tell us what you can see. If you have these details, they can help us give you a useful answer faster:

• Which drains are affected, and how many
• Whether the house is on city sewer or a septic system
• Roughly how old the house is
• Whether this line has clogged before, and when it was last cleared
• Photos of the fixture or the cleanout, if you can send them

Can you get an exact price over the phone? Usually, not down to the dollar. The final cost depends on the five factors above, and some of those details may need to be seen in person. You can still call us and get a straightforward conversation about what may affect the price of your particular job.
