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 Alexandria
Before anyone cables a drain in Alexandria, look at the weather. The City says the overload on its sewer in a heavy storm generally lasts 2 to 6 hours, and August 15, 2021 brought 3 to 5 inches of rain in about an hour and sanitary backups with it. A drain that gurgles in the downpour and settles by supper is the street catching up. A drain that stays slow after the sky clears is a clog, and that one we can open.
Old Town is the long, narrow end of the job. Nearly 3 in 10 of the City’s owner homes predate 1960, and the street sewer under Old Town goes back to the 1800s. In a rowhouse the kitchen is often at the back, so its line runs the whole length of the house to the street. Grease that cools halfway along settles there, a long way from the sink. We start at the nearest cleanout and tell you how far the cable had to travel.
More than half of Alexandria’s owner homes, 53 in 100, are condos or apartments, and 21 in 100 are townhouses. In a building, the slow drain is either the branch under your sink or the stack serving the floors above and below. If the unit next door is fine, it’s your branch. We clear from the sink, tub or washer standpipe and stop where the cable meets the shared pipe.
Toward Kingstowne and Franconia the houses are younger: a third of the owner homes on the county side went up between 1980 and 1999, and a quarter are townhouses. That is mostly plastic pipe, so a stubborn clog there is usually what went down it, grease and wipes and the toy that went in with the bath water. A cable through the cleanout ends most of those in one visit.
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 |
|---|---|---|---|---|
| City of Alexandria | 1970 | condo and apartment buildings, about 5 in 10 | gas, about 6 in 10 | Your branch drains; the building’s stack. |
| Rose Hill | 1969 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Scale in cast iron under the floor. |
| Franconia | 1986 | townhouses, about 5 in 10 | electricity, about 6 in 10 | Wipes and grease in PVC; a low spot outside. |
| Fort Hunt | 1963 | single-family houses, nearly all | gas, about 8 in 10 | Roots in clay joints out in the yard. |
| Kingstowne | 1994 | townhouses, about 5 in 10 | gas, about 7 in 10 | Wipes and grease in PVC; a low spot outside. |
| Woodlawn | 1976 | townhouses, about 4 in 10 | electricity, about 6 in 10 | Scale in cast iron under the floor. |
| Lincolnia | 1982 | single-family houses, about 4 in 10 | gas, about 7 in 10 | Wipes and grease in PVC; a low spot outside. |
| Mount Vernon | 1967 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Scale in cast iron under the floor. |
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 long Old Town row the kitchen branch has the farthest to run, so it’s the one that fills up after a heavy cooking week. Scrape pans into the trash and let the disposal run cold water for a count of thirty. If the sink is still slow tomorrow, it’s past the trap.
In houses this age the line to the street is often clay or cast iron, and roots find the joints. Clearing works, but if it keeps coming back, the camera says whether a repair would end it.
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.

Choosing who clears it
Questions to ask anybody who offers to clear a drain, us included.
Cabling a line the street has overloaded is clearing the wrong pipe. A good plumber asks whether the drain recovers once the rain stops, and puts the cable in when it doesn’t.
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.

Hard to find service like this in Alexandria.
…we had swift and professional responses for multiple plumbing and HVAC needs in our Rosemont Alexandria condo
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
Often it’s smaller: the washer’s trap or the short branch behind it, where lint packs into a mat. Ask whether the units around you have the same trouble. If they do, the stack is the likely suspect and the association handles it. If it’s only you, we clear your branch.
Probably not for the clog, because a drain that clears itself within a few hours of the rain ending was the street sewer, not your pipe. If it happens every storm, a camera look, $89 added to a visit, shows whether a backflow valve belongs on your line.
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.
