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.

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 Sterling
In Sterling, 35 in 100 owner homes are townhouses and another 15 are in condo or apartment buildings. Fewer than half are detached, which is rare for Loudoun. That puts a question ahead of the machine: is this your branch, or a line you share? A slow tub is yours. A basement drain that fills when a neighbor runs the washer is not. We ask on the phone, because the answer tells us where to start.
More than half of Sterling’s homes date from the 1980s and 90s, a bigger share than anywhere else in the county, and about three in ten renters live in them. Rentals change what a clog is made of. Turnover means grease from a thousand different cooking habits, wipes, paper towels and hair. Landlords and property managers get the same answer from us as owners do: we’ll show you what came out of the line.
Sterling Park, the oldest part, is where many ramblers and split-levels from the 1960s and 70s sit. Houses like that are often on a slab or have a shallow crawlspace, so the drain runs under the floor and the cleanout, where there is one, is outside. The first sign of trouble in one is the lowest tub on the main floor draining slowly. We’ll cable from the cleanout, not through a toilet, when we can.
North of Route 7, Countryside, Cascades, Sugarland Run and Lowes Island are mostly townhouse clusters and 80s and 90s single-family streets. Those lines are plastic, and the clogs sit at the kitchen, where a disposal has fed the pipe for thirty years, and at the laundry. One in four Sterling homes is from 2000 or later, and those get wipes and toys far more than anything else.

By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Which clog it is
In a Sterling townhouse row, the middle unit’s floor drain is the first to show a shared-line clog, because the end units sit closer to the street. If yours is the middle unit and the others are fine, the trouble may be at your own connection. Tell us which unit you’re in.
Townhouse rows often share a line before it reaches the street. If a neighbor is fighting the same clog, tell us, because the fix may be on common pipe the association handles.
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.
In Sterling the answer decides where the cable stops and who gets the call. A plumber who asks has cleared a building stack before. One who doesn’t may clear your unit and leave the shared line for the next backup.
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.

Nii is the best. He’s been to the house twice – once for a galvanized to PVC piping change-out, and another time for a badly clogged kitchen line that wouldn’t budge with my snake and a good bit of effort. Super nice guy, very skilled, fair, calm, etc. Exactly what you want in a plumber.

Questions
Call your landlord first, since the pipe and the bill are theirs to decide. If they want us to handle it, we’ll work with them directly and show them what came out of the line.
If only the kitchen is slow, it’s the kitchen branch. If the lowest tub on the main floor gurgles too, it’s the main. Either way we clear it from the sink or the outside cleanout, and we’ll tell you which it was.
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.
