Seattle drain cleaning, at a glance
Home Comfort Alliance's licensed plumbers do drain cleaning in Seattle homes. We clear clogged indoor drains: kitchen and bathroom sinks, tubs, showers, toilets, laundry drains and the drain pipes inside your house. We clear indoor drains, including main drain lines from an indoor cleanout. We don't do sewer line work.
Drain cleaning is $148 and hydro jet cleaning is $399 to $574. The $99 plumbing dispatch fee is charged on top of the drain cleaning price, and you get the price before any work begins. Book by phone or online. Our plumbers work Monday to Friday, 8 AM to 5 PM, with same-day service when possible.
Water backing up right now? Stop running water and flushing in that part of the house, and don't keep plunging a toilet that is close to overflowing. Then check one thing: when you flush a toilet, does water come up in a tub, shower or floor drain on the lowest level? If it does, the clog is probably in the main drain line, not one fixture. Tell us that when you book. If sewage comes up from a floor drain or the yard, see what we don't do below.
Signs you need drain cleaning
- A sink, tub or shower that drains slowly
- Standing water in the shower or tub after you finish
- A toilet that clogs again and again
- Gurgling from a drain when water runs or a toilet flushes
- A bad smell coming from a drain
- The same clog coming back after plunging or store-bought cleaners
- Water backing up into a nearby fixture, such as the tub when the sink drains
One slow drain is usually a quick fix. Several slow drains at once tell us where to look, as the next section explains.
One slow drain or the whole house? How to tell
Where the water backs up tells you where the clog is, and who can clear it. Seattle Public Utilities splits it the same way: a plumber for fixtures and the pipes inside the house, and a rooter service or side sewer contractor for the side sewer that runs from your house to the city sewer.
| What you see | Where the clog usually is | Who clears it |
|---|---|---|
| One sink, tub, shower or toilet is slow or blocked | That fixture's drain or trap | Our plumbers (drain cleaning, $148) |
| Two fixtures on the same floor are slow, such as a sink and a tub | The branch drain line they share | Our plumbers |
| Flushing a toilet backs water up into a tub, shower or floor drain on the lowest level | The main drain line inside the house | Our plumbers, from an indoor cleanout |
| Sewage comes up from a floor drain or yard cleanout, roots keep returning, or the pipe outside is broken | The side sewer outside the house | A rooter service or side sewer contractor (we don't do sewer line work) |

What our plumbers clean
Kitchen sinks
Grease, food scraps and coffee grounds build up in the trap and the pipe behind the wall. Kitchen lines that clog again and again are the most common reason we recommend hydro jet cleaning.
Bathroom sinks, tubs and showers
Hair, soap and toothpaste collect in the trap and the first few feet of pipe. A cable usually clears these in one pass.
Toilets
Wipes, too much paper or a dropped object. If the toilet backs up into a tub or floor drain when you flush, the main drain line is the likely spot.
Laundry drains
Lint and soap from the washer can slow the standpipe and the drain it empties into.
Main drain lines from an indoor cleanout
When several drains back up at once, we clear the main drain line from a cleanout inside the house. That is where our work stops: we don't do sewer line work.
Drain snake or hydro jet: which does your drain need?
| Method | How it works | Best for | Our price |
|---|---|---|---|
| Drain cleaning (cable or snake) | A rotating cable breaks up the clog and pulls it out of the pipe | Single-fixture clogs: hair, wipes, a toilet blockage, a dropped object | $148 |
| Hydro jet cleaning | A high-pressure stream of water scours build-up off the inside of the pipe walls | Grease and sludge build-up and clogs that keep coming back in indoor drain lines | $399 to $574 |
Your plumber looks at the drain first and recommends one method. You get the price before any work begins, and nothing is done until you approve it.
What we don't do: sewer lines and side sewers
We clear indoor drains, including main drain lines from an indoor cleanout. We don't do sewer line work. That means we don't repair, replace or camera-inspect sewer lines or side sewers.
In Seattle, if you own your home, you also own your side sewer, the pipe that runs from the house to the public sewer (Seattle Public Utilities). For a clog in that pipe, SPU suggests a rooter service. For a broken or leaking side sewer, it suggests a side sewer contractor. Tree roots in the line, sewage coming up from a floor drain or a yard cleanout, and drains on every floor backing up at once are signs the problem is in the side sewer. If sewage is backing up into your home, SPU asks you to call them as well; their contact details are in the SPU troubleshooting guide.
Not sure which side of the house the clog is on? Tell us what you see when you book, and we'll tell you honestly if it isn't a job for us.

Why Seattle drains clog
- Kitchen grease. Seattle Public Utilities names cooking oil and grease as a main cause of blocked pipes. Grease cools and sticks to the pipe walls, then catches food and soap.
- Wipes and other non-paper items. SPU lists wipes among the things that block pipes, including wipes sold as "flushable".
- Hair and soap in bathroom sinks, tubs and showers.
- Older houses. Many Seattle homes have older drain piping with more joints and bends where build-up collects.
- Roots are a side sewer problem, not an indoor drain problem. If roots are in the line, you need a side sewer contractor.
How to prevent clogs
- Wipe greasy pans and put fats, oils and grease in the trash, not the sink.
- Use strainers in tubs, showers and the kitchen sink, and empty them often.
- Flush only toilet paper. Wipes go in the trash, even "flushable" ones.
- Run plenty of water after using a garbage disposal.
- Don't rely on repeated chemical drain cleaners. If a drain keeps clogging, have it cleared mechanically.
- Call while the drain is slow, before it stops completely.

A recent Seattle plumbing job: Central District
In October 2026 one of our plumbers visited a home in Seattle's Central District where the kitchen garbage disposal was leaking from the bottom. The plumber installed a new 1/2 HP disposal, reconnected it to the existing kitchen sink drain and power, and tested it: it ran with no leaks. It wasn't a clog, but it was on the same kitchen sink drain our drain cleaning covers.

Seattle drain cleaning FAQ
How much does drain cleaning cost in Seattle?
At Home Comfort Alliance, drain cleaning is $148 and hydro jet cleaning is $399 to $574 (prices as of September 2026). The $99 plumbing dispatch fee is charged on top of the drain cleaning price. You get the price before any work begins. For comparison, Angi's regional estimate for drain cleaning in Seattle is an average of $373 (updated February 2026).
Should I get my drain snaked or hydro jetted?
Snaking (drain cleaning, $148) works for most single-fixture clogs, such as hair or a toilet blockage. Hydro jetting ($399 to $574) scours grease and build-up off the inside of the pipe and suits kitchen lines that keep clogging. Your plumber recommends one after checking the drain.
Several drains are backing up at once. Can you fix that?
Often, yes. If two fixtures on the same floor are slow, it is usually a shared indoor line. If flushing a toilet backs water up into a lower drain, the main drain line is likely blocked, and we clear it from an indoor cleanout. If sewage comes up from a floor drain or the yard, the problem is probably in the side sewer, which we don't work on.
Do you clean sewer lines or side sewers?
No. We clear indoor drains, including main drain lines from an indoor cleanout. We don't do sewer line work, and we don't repair, replace or camera-inspect sewer lines or side sewers.
Who is responsible for the side sewer in Seattle?
According to Seattle Public Utilities, if you own your home you also own your side sewer, up to the public sewer. For a clog in the side sewer, SPU suggests a rooter service; for a broken or leaking side sewer, a side sewer contractor.
Do you offer emergency drain cleaning?
Our plumbers work Monday to Friday, 8 AM to 5 PM, and we don't offer after-hours plumbing service. Book by phone or online: a request made after hours is scheduled for the first available business-hours appointment, with same-day service when possible.
Are chemical drain cleaners safe to use?
They may loosen a clog for a while, but repeated use can leave the blockage in place. If a drain keeps clogging, have a plumber clear it mechanically.
Are "flushable" wipes safe to flush?
Seattle Public Utilities lists wipes among the items that block pipes. Only toilet paper should go down the toilet.
Why does my drain keep clogging?
Usually because the build-up was only partly cleared, or the same things keep going down the drain: grease, hair and soap. Hydro jet cleaning removes build-up along the pipe walls in indoor lines. If clogs keep returning across the whole house, the side sewer may be the cause.
Is your plumber licensed?
Yes. Home Comfort Alliance holds WA Plumbing Contractor License #HOMECCA751QG (residential) and WA Contractor Registration #HOMECCA785BD, and is licensed, bonded and insured in Washington.
Are there any discounts on drain cleaning?
Yes: 10% off indoor drain cleaning, and $50 off same-day plumbing repairs. Offers cannot be combined with other offers or Club pricing and do not apply to the trip charge. Home Comfort Club Plumbing members ($15 a month) get member pricing on repairs and priority scheduling.
I rent my home. Can I book drain cleaning?
Yes, when you're the one paying for the visit. Otherwise we'll take your landlord's details and call them.
