Your basement laundry is the canary
A washer dumps a lot of water fast. If the basement floor drain bubbles during a load, the main is partly blocked. Don’t wait for it to overflow before you call.

What it costs
What drain cleaning costs in Oakton.
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 Oakton
Oakton is a basement town, with the bath and laundry at the bottom of every line.
Fairfax County’s records show a basement under 3,953 of the 4,085 single-family homes in 22124, about 97 in every hundred. Basements in Oakton are lived in: a bath, a laundry, a bar sink, sometimes a second kitchen for an in-law suite. Every one of those fixtures sits at the lowest point of the plumbing, so the first sign of a clogged main is a basement drain, not an upstairs one.
The decade splits the town. About 37 percent of homes predate 1980, and nearly half went up in the 1980s and 90s. A 1970s Oakton house usually has cast iron under the basement slab, and the kitchen branch narrows with scale. A 1980s or 90s house is plastic, and a clog is hair, grease or paper. We ask the year of the house first, because it sets our expectation of what the cable will bring back.
One in five Oakton homes is a townhouse, and nearly three in ten across the Oakton CDP are condo or apartment buildings. In a townhouse row, ask the neighbor. When two basements back up at once, the clog is somewhere past both, and we stop at the edge of what’s yours. In a condo, call management first, since a clog in a stack serves several units.
Plenty of Oakton basements were finished years after the house went up, with a bath or a bar sink tied into the nearest line. When a basement sink fills slowly while the rest of the house drains fine, that added branch is the first place we look.

Which clog it is
One slow drain, or the whole house backing up in Oakton.
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 Oakton.
Questions to ask anybody who offers to clear a drain, us included.
Do they check the lowest drain first?
In a basement house, the lowest drain shows a main line problem first. A plumber who only checks the slow upstairs sink may clear the wrong line.
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 Oakton.
The basement shower in my Oakton house is slow but the upstairs ones are fine. Why?
The basement shower sits lowest on the line, so it feels any narrowing first. If it’s slow with the laundry off, the clog is likely in that branch; if it worsens when the washer runs, it’s the main.
Can you clear a drain in a basement bar sink?
Yes. Those lines are often small and long, and we use a smaller cable so we don’t damage the trap.
How much does drain cleaning cost in Oakton?
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.
