A guest bath that never gets used still clogs
Big houses have bathrooms nobody uses for months. Water in an unused trap evaporates, and a dry trap lets sewer smell into the room. Run the water in every drain once a month.

What it costs
What drain cleaning costs in Great Falls.
Where the clog sits decides the price. A sink, tub or shower drain is one fixture. When every drain in the house is slow or water comes up the lowest one, it’s the main line, and that’s a bigger machine and a longer run.
Drain cleaning, one fixture
$200 to $800
Main sewer line cleaning
$550 to $1,650
Sewer camera inspection, added to a visit
$89
Prices checked .
If the main line clogs again inside a year, or the cable comes back with roots, a camera look for $89 on the same visit tells you whether it’s a clog or a broken pipe. We show you the picture either way.
Comfort+ membership is $199 a year for four visits: a dryer vent cleaning, a water heater flush with a sewer camera inspection, a heating maintenance visit and a cooling maintenance visit.
What’s different in Great Falls
In Great Falls there is no association stack and no neighbor’s line, so every clog is yours.
Great Falls is the most single-family town we serve. Fewer than one home in a hundred is anything but a detached house, so there are no condo stacks, no townhouse rows and no shared lines to sort out. A slow drain is yours, and what we do is trace it: one fixture, one branch, or the main run inside the house. We start by asking which drains are slow and which are fine, because that map points to the clog.
The houses come in three ages. About four in ten predate 1980, with cast iron and scale in the older kitchen lines. Close to half were built in the 1980s and 90s, and another one in six since 2000. An older Great Falls house is often a big one that has been added onto, so the drain from a far wing may run forty feet before it joins the rest. A long run with little fall is where grease and paper settle.
Large houses also mean large entertaining. A holiday dinner for twenty can push a kitchen line that has been marginal for years over the edge, with a dishwasher, a disposal and a prep sink all feeding one branch. Run it hard before the party and you’ll know. If the sink holds water, call us earlier in the week.
For homes on the larger lots, the drains inside the house are what we do, and what we clear. If the cable runs clean to the first cleanout and the trouble persists, we’ll tell you plainly and show you what we saw, so you know who to call next. The first cleaning is a price you hear before we start, and a main line is priced separately from a single fixture.
By the numbers
Great Falls houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Great Falls
- Median home built1986 Census
- Built before 1980about 4 in 10 Census
- Built since 2000about 2 in 10 Census
- Most homes aresingle-family houses, nearly all Census
- Heated withgas, about 5 in 10 Census
- Rentedhardly any Census
- Houses from the 80s and 90s mostly drain through PVC, so a main line clog there is usually what went down it, or a low spot in the yard.
Which clog it is
One slow drain, or the whole house backing up in Great Falls.
Only one sink or tub is slow
If the kitchen sink backs up but the bathroom drains fine, the clog is in that branch, usually grease or food in the kitchen, hair and soap in a tub. That’s a one-fixture clearing.
Water comes up the lowest drain
When the washer drains and water shows up in a basement shower or floor drain, or flushing a toilet bubbles the tub, the clog is past the branches in the main line. Stop running water until it’s cleared.

Choosing who clears it
How to pick the best plumber for drain cleaning in Great Falls.
Questions to ask anybody who offers to clear a drain, us included.
Do they ask which drains are slow and which are fine?
In a house with many bathrooms, that map tells the plumber whether it’s a branch or the main run. If they skip it and just push a cable, they’re guessing.
Do they price it before they run the cable?
You should hear whether it’s a one-drain clearing or the main line, and the price for it, before anybody feeds a cable in. A price that shows up after the work is a bad sign.
Do they push chemicals or a new line on the first visit?
A clear drain doesn’t need a bottle of anything, and a single clog is not a reason to dig. If someone jumps to replacing the sewer line without a camera picture, get a second look.

Questions
Drain questions from Great Falls.
The basement bath in my Great Falls house gurgles when the washer drains. What is it?
The basement bath is the lowest fixture, so a partial blockage in the main run shows there first. Stop running water and call us; clearing it now is simpler than after it backs up.
How do I know if my Great Falls house needs a main line clearing or one fixture?
If only one drain is slow, it’s a fixture. If two or more are slow, or water rises in the lowest one, it’s the main line, and the machine and the price are bigger.
How much does drain cleaning cost in Great Falls?
One clogged sink, tub or shower drain is $200 to $800. A main line backing up into the house is $550 to $1,650. Where the clog is and how far down it sits moves the number inside that range.
Should I pour a drain cleaner in first?
Better not. The strong ones can sit in the trap, damage older pipe, and splash back on whoever opens the drain next. Try a plunger on a sink or tub, and if that doesn’t move it, call.
