01Who we are and what we do
This website, drainauthority.pro, is operated by The Drain Authority LLC (“The Drain Authority,” “we,” “us”), 5608 17th Ave NW, Suite 2025, Seattle, WA 98107. We are drain and sewer specialists serving Seattle and nearby communities across King and Snohomish counties. See the full list of cities we serve.
We are a registered contractor with the Washington State Department of Labor & Industries, registration number DRAINDA756MA. You can check our registration, bond and insurance status any time with L&I’s Verify a Contractor tool.
Our work is drain and sewer cleaning, clog clearing, hydro jetting, pipe descaling and sewer camera inspection. We are not a general plumbing company. If we find a problem that needs repair or replacement outside that work, we will show you what we found and tell you so plainly.
By booking service with us or using this website, you agree to these terms. If a written estimate, invoice or signed agreement for a specific job says something different, that written job paperwork controls for that job.
02Using this website and our tools
Our guides explain how drain and sewer problems work and what they typically cost. Price ranges in articles such as our Seattle drain cleaning cost guide describe typical jobs at the time of writing. They are not a quote for your property.
The Free Drain Diagnostic gives general guidance based on the answers you enter. It cannot see inside your pipe, and its result is not a diagnosis. If sewage is backing up into your home, stop using water and call us.
Please do not try to disrupt the site, access areas that are not public, or submit false service requests.
Our content
The text, photos, video and research on this site belong to The Drain Authority or are used with permission. You are welcome to link to any page and quote short passages with credit and a link back. Reporters and researchers may cite our reports the same way. Please ask before republishing full articles, images or video.
03Requesting service and scheduling
You can request service by phone at (206) 590-1455, through our contact form, or with online booking. A request is confirmed once we confirm a date and an arrival window with you.
- Same-day service is offered when the schedule allows. It is not guaranteed.
- Arrival windows are estimates. Traffic and emergency calls can move them, and we will let you know if we are running behind.
- Access: please clear a path to the affected fixtures, cleanouts and crawl spaces, secure pets, and tell us about any hazards you know of.
- Authorization: someone who can approve the price should be on site or reachable by phone. If you rent, main line and sewer work may need approval from the owner or property manager.
04Pricing, estimates and payment
You get a flat price for the job we have described before any work starts. That price is based on what we can see and what you tell us about the problem. There is no trip fee for us to come out and look.
We do not advertise a low lead price and raise it at the door. Our article on $99 drain cleaning ads explains why that matters.
If the job changes
Drain problems are often hidden. If we find a second blockage, heavy roots, broken or collapsed pipe, or a line we cannot safely access, we stop, explain what we found and give you a revised price before we continue. You can decline the added work.
Payment
Payment is due when the work is complete unless your invoice or a written agreement says otherwise. We accept cash, credit cards and debit cards. Commercial and property management accounts follow the payment terms in their written agreement.
For residential jobs of $1,000 or more, Washington law (RCW 18.27.114) requires us to give you a written disclosure statement before work starts. It explains our registration and bond and your rights regarding liens.
05Cancellations and rescheduling
Plans change. If you need to cancel or move an appointment, call us as early as you can at (206) 590-1455 so we can offer the time to someone else. If a cancellation fee applies to your appointment, we will tell you when you book.
If we need to reschedule because of an emergency call, equipment trouble or unsafe conditions, we will contact you promptly to set a new time.
06Your property and the condition of your pipe
Who owns the sewer line
In Seattle, the side sewer that runs from your house to the public sewer main belongs to the property owner, including the section under the sidewalk and street (Seattle Municipal Code 21.16). Other cities set their own rules, so check with your local utility. Our Ballard Side Sewer Report walks through what that means in practice.
Older and damaged pipe
Many homes in our service area still have decades-old cast iron, clay or Orangeburg pipe. Cleaning removes what is inside a pipe. It cannot strengthen pipe that is already cracked, corroded, offset or collapsing, and pipe in that condition can fail during or after cleaning.
On older lines, and before hydro jetting a line we have not seen, we usually recommend a sewer camera inspection first. It shows whether the pipe can handle the cleaning method before we use it.
We are not responsible for the failure of pipe, joints, fittings or fixtures that were already deteriorated, improperly installed or damaged before we arrived, or for damage caused by conditions we could not see or reasonably detect. This does not limit our responsibility for damage caused by our own negligence.
If there is no usable cleanout, reaching the line may mean removing a toilet, trap or fixture. We will explain what is involved and get your approval first.
07Camera inspections, photos and video
A sewer camera inspection records what is visible inside the pipe on the day of the inspection. It is not a guarantee of the pipe’s future condition, a code or permit inspection, or a substitute for a full home inspection.
Standing water, debris, sharp bends and pipe size can limit how far a camera travels and what it shows. We will tell you if part of the line could not be inspected.
We may take photos and video to document the job. We will not publish images or footage that identify you or your address without your permission.
08Warranties and repeat clogs
Any warranty, guarantee or follow-up visit on a job is the one written on your estimate or invoice, with the length and conditions listed there. Beyond that written warranty and the rights you have under Washington law, we do not make other promises about how long a line will stay clear.
Drains can clog again for reasons outside our control: tree roots growing back, grease or wipes going down the line, or pipe defects shown on camera. A new clog from those causes is not a defect in our work, and we will explain your options for preventing a repeat.
09Limitation of liability
To the fullest extent Washington law allows, we are not liable for indirect, incidental or consequential losses arising from our services or this website, such as lost business income or temporary lodging costs.
Except for damage caused by our negligence or willful misconduct, our total liability for any claim related to a job is limited to the amount you paid for that job.
This website and its tools are provided as they are, without promises that they will always be available or error-free.
Nothing in these terms limits rights you have under the Washington Consumer Protection Act (RCW 19.86) or any other law that cannot be waived.
10Third-party services and links
Online booking runs through Housecall Pro, maps are provided by Google, and our reviews live on outside platforms. When you use those services, their own terms and privacy policies apply. Links to other websites are provided for convenience, and we are not responsible for their content.
How we handle your information is covered in our Privacy Policy.
11Governing law and disputes
If something goes wrong, call us first at (206) 590-1455. Most problems get solved faster in a conversation than in a letter.
These terms are governed by the laws of the State of Washington. Any lawsuit related to these terms or our services will be brought in the state or federal courts located in King County, Washington, unless the law requires otherwise.
If any part of these terms is found unenforceable, the rest of the terms still apply.
12Changes to these terms
We may update these terms from time to time. The date at the top of this page shows the current version. The terms in effect when you booked a job apply to that job. These terms were last updated on September 11, 2026.
