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 Leesburg
Leesburg’s biggest group by age is the 1980s and 90s: four homes in ten, and the typical owner house dates from 1996. That’s the age where PVC kitchen lines have had thirty years of dinners on them. They don’t fail, they fur up. A sink that used to clear in seconds now takes a minute, and one more big meal tips it over. Opening that line with a cable and then jetting the grease off the walls is the usual fix.
Around King and Market streets and the blocks beside them, the houses are older, and a drain call is a different job. A bathroom added in the 1950s upstairs at the back, a kitchen stack in cast iron, a basement with a floor drain that connects who knows where. We cable these slowly and tell you what comes back. Rust flakes and clay grit in the cable are the pipe talking, and we’ll say so before anyone suggests more.
Three in ten Leesburg homes are townhouses, and close to two in ten are in condo or apartment buildings, a bigger share than most Loudoun towns. In a townhouse row, a first-floor half bath or basement drain filling is the sign of a clog on the line your house owns. In a building, water coming up in a bottom-floor unit while the building does laundry above you is the stack, and your manager’s call.
Lansdowne is its own case: nearly nine in ten homes built since 2000 and close to four in ten in condo buildings. A drain there is almost always a branch clog, hair in a tub, grease in a kitchen sink, a wipe in a toilet. We clear it from your fixture. If the cable wants to keep going into the building’s stack, we stop at your wall and tell you who to call.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and where houses that age usually clog.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Inside the town limits: the Old and Historic District downtown, Exeter and Carrvale inside the bypass, Potomac Station and Edwards Landing outside it.
Lansdowne only. It’s the one Census place outside the town limits, so the farms and lots beyond it aren’t in these figures.
Which clog it is
Holiday weekends are when a Leesburg kitchen line gives up, especially in a house with a disposal and thirty years of grease inside the pipe. If the sink holds water the morning after, don’t pour a chemical down it. Call, and we’ll clear it before the next meal.
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.
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.

Choosing who clears it
Questions to ask anybody who offers to clear a drain, us included.
The answer decides whose pipe the clog is in, and where the cable stops. A plumber who asks has run into a building stack before. One who doesn’t may clear your unit and leave you with the same backup next week.
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.

Questions
Usually the line past the trap is coated with grease and the opening is narrower than it should be. A cable punches through it, and a jetter pass washes the walls so the slowdown doesn’t come back in a month.
Yours, most likely. If only your tub is slow while the other fixtures are fine, the clog is in the branch, and that’s the part we clear. Several units slow at once would point at the stack.
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.
