What it costs
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

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 Warrenton
Warrenton’s town code spells it out. The Town clears stoppages in the public main, and the owner clears the house sewer. If a house sewer stays blocked, the Town can give 48 hours’ written notice, clear it, and bill the owner the cost plus 20 percent. That is a good reason to deal with a slow main drain before it becomes a backup, and a clear reason to call us and not a letter.
The town is a real mix. About 28 percent of owner homes were built before 1960, and that’s cast iron and old clay in the older streets near downtown, where roots and scale are the usual causes. Another 35 percent went up from 1980 to 1999, in plastic, and the median is 1993. For each, we choose the cutter or cable by pipe type, not by guess.
Warrenton has plenty of attached housing too: about one in five owner homes is a townhouse, and more than one in ten is a condo. In a townhouse row, the house sewer often joins a shared run before it meets the main, and a clog there can back up into more than one house. Knowing who shares the run matters before we start.
The Town’s own standards help us here. A lateral is supposed to be 4 inches, laid at a 2 percent slope, with a cleanout at least every 50 feet. Houses that follow that give us an easy start. Houses without a cleanout we work from a fixture or the roof vent, and we’ll tell you where one should go so the next clearing is quick.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and where houses that age usually clog.
| Place | Median home built | Most homes are | Heated with | Where it usually clogs |
|---|---|---|---|---|
| New Baltimore | 1999 | single-family houses, nearly all | gas, about 5 in 10 | Wipes and grease in PVC; a low spot outside. |
| Warrenton | 1993 | single-family houses, about 5 in 10 | gas, about 6 in 10 | Wipes and grease in PVC; a low spot outside. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Inside the town limits, a little over 4 of the roughly 110 square miles the two Warrenton ZIP codes cover: the Historic District around Main Street, Leeds Square, and the streets off Broadview Avenue and Alwington Boulevard.
New Baltimore only. It’s the one Census place on the county side with mostly Warrenton mail, so the farms and lots beyond it aren’t in these figures.
Which clog it is
A basement drain is the lowest opening on the house sewer, so it shows a partial blockage first. If it bubbles during a wash and the toilets are slow, the house sewer is narrowing and a cable should go in soon.
New PVC rarely fails, so in a house this young a clog is almost always something that went down: wipes, grease, a toy. One clearing usually ends it.
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.

Choosing who clears it
Questions to ask anybody who offers to clear a drain, us included.
A crew that works in Warrenton should. Ask where the cable stopped, in feet from the cleanout. If it passed the property line, the stoppage may be in the Town’s main, and that one is the Town’s to clear.
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.
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.

Plumber showed up on time and fixed my drain clog without issue. Very reasonably priced as well. Highly recommended.
Questions
Yes, if the sewer stays blocked after 48 hours’ written notice. The Town clears it and bills cost plus 20 percent. Clearing it yourself first avoids that.
Yes. We work from a fixture or the roof vent, and we can show you where to add a cleanout so every clearing after is simpler.
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.
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.
