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.

What’s different in Catharpin
Catharpin is small. The Census counts 377 housing units in ZIP 20143, all of them in Prince William County, and they come from every era: a farmhouse from long ago, a 1980s build next to it, a house put up in the last twenty years across the road. That mix means no rule of thumb about drains around here holds. A 1950s kitchen line and a 2010s one fail in opposite ways.
In an older house the drain pipe inside is often cast iron, sometimes galvanized steel, and the trouble is narrowing: a bit of scale each year until the kitchen sink empties like it’s draining through a coffee stirrer. In a newer one the pipe is smooth plastic, and a clog is whatever went down it, grease or wipes. A two-minute call about the house’s age lets us bring the right tool.
These are detached houses on larger lots, and larger lots mean houses that spread out. A bathroom at one end and the laundry at the other can sit on a long, shallow drain run, and shallow runs hold what the rest of the house sends down them. A tub at the far end can clog while the kitchen is fine, and that’s a branch, not a main line.
There’s no neighbor sharing your wall to compare notes with out here, so when every drain in the house is slow at once, the trouble is on your own line, and we treat it that way. A clog we can reach with a cable clears in one visit. One that returns inside a year means the pipe has changed, and we’d rather show you with a camera look, $89, than clear it a third time.
Which clog it is
In a big house with a guest bath used a few times a year, a dry trap can smell like a sewer and send everyone looking for a clog. Run the water for a minute first. If the smell stays gone and the drain runs freely, there was no clog.
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.
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
Questions to ask anybody who offers to clear a drain, us included.
In a farmhouse with an addition, the original pipe and the newer branch behave differently. A plumber who asks about both is planning where to put 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.
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
Not likely. If the bathrooms run freely, the main line is open. The kitchen has its own run, and it’s usually grease, or scale in an older iron pipe. That’s a one-fixture clearing.
Does it clear for a few weeks, then slow again? That’s usually grease or hair rebuilding, and it points to habits we can help change. Does it never run right even after clearing? That points to the pipe, and a camera shows it.
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.
