The short answer
Drain cleaning clears a blocked or slow drain by running a cable or water jet through the pipe from the nearest access point. In Seattle ours runs $200–$600 flat for a kitchen, bath, laundry or floor drain, with no trip fee and the same rate evenings and weekends. The owner answers 8 AM to 8 PM, seven days, and same-day service is available when the schedule allows.

One flat price for the whole job, quoted after we see the line and before any work starts.
We clear the drain from the access point that reaches the whole blockage, not just the part you can see, then run water to prove it flows. On a main line, the visit ends with a camera pass.
Most single-fixture clogs are cleared with a cable in under an hour. When the cable comes back coated in grease or root hair, that tells us the line needs hydro jetting to stay open, and we will say so before you pay for a second visit.
Four causes account for most of what we pull out of drains in this city. Each one is backed by a public source you can check.

01
Seattle Public Utilities says roots are a common problem in side sewers, and older concrete and clay pipe built without watertight joints is especially at risk.

SPU calls it a myth that liquid oils will not clog pipes. Many cooking oils, like olive and coconut oil, harden in cooler pipes and cause blockages.

Bellevue Utilities notes the drain connecting a home to the sewer is only about four inches wide, which is why grease, wipes and food scraps add up fast.

An N.C. Cooperative Extension urban forester notes that highly caustic drain cleaners can damage older sewer pipes, creating openings roots can use.

What you do now decides how much there is to clean up later. Most of this comes straight from Seattle Public Utilities’ sewer backup guidance.
01
No flushing, no washer, no dishwasher, no showers upstairs. Every gallon you send goes to the lowest drain in the house.
02
Keep children and pets away from sewage. SPU says to turn off power to a flooded area and not to stand in water near electrical equipment.
03
SPU advises against trying to stop sewage coming up through a floor drain. It will find the next lowest opening.
04
Tell us which fixtures are affected and whether anything gurgles. That usually tells us branch line or main before the truck moves.
05
SPU’s guidance: call Puget Sound Energy at 1-888-225-5773 before clearing a side sewer blockage, to avoid damaging a gas line.
06
Photos and receipts matter for insurance. If the city’s sewer caused it, SPU explains how to file a damage claim with the City.
Most drain calls are cleared in one visit. A single fixture is usually under an hour; a root-blocked main line can take three.

Every clog has a cause, and you get to see it. These are from real calls.
A mechanical cable with the right cutting head opens most branch and main line blockages the same visit.
4,000 PSI water scours the pipe wall clean, and older clay and cast iron get a camera pass before any jetting.
Main line calls end with a camera pass, so you see what caused it, how far out it sits, and that it is gone.

Drain cleaning with us runs $200–$600, flat, for a kitchen, bath, laundry or floor drain. Hydro jetting runs $500–$700 when grease or roots keep coming back. There is no trip fee, and evenings and weekends cost the same as a weekday. Seattle Public Utilities’ homeowner guide says side sewer cleaning generally costs less than $1,500.
No. The Drain Authority answers the phone 8 AM to 8 PM, seven days a week, and takes online bookings around the clock. For an overflowing public sewer or sewage coming from the street at any hour, Seattle Public Utilities runs a 24/7 line at (206) 386-1800.
Same day when the schedule allows. Morning calls generally go out the same afternoon, and late-day calls get the first slot the next morning. Calling instead of booking online is the fastest way to learn the earliest arrival time.
Stop using water everywhere in the house, keep people and pets away from any sewage, and turn off power to a flooded area. Seattle Public Utilities says not to try to stop sewage coming up through a floor drain, and to document any damage for insurance.
Not in older pipes. An N.C. Cooperative Extension urban forester notes that highly caustic drain cleaners can damage older sewer pipes and create openings roots can use. Chemicals also sit in a full line and end up in the way of whoever clears it.
One slow fixture with everything else draining normally is a branch line. Several fixtures slowing together, a toilet that gurgles when the washer drains, or water coming up the lowest drain in the house points to the main line, which is a main sewer line cleaning instead.
A single sink or tub, often yes. For the main line, Seattle Public Utilities advises calling Puget Sound Energy at 1-888-225-5773 before clearing a side sewer blockage so a gas line is not damaged, and a cleared main line should get a camera pass to show the cause.
No. We clean drains and sewer lines, jet them, descale cast iron and run cameras. We do not dig up or replace sewer pipe, so we have nothing to gain by recommending a replacement you do not need.
