Our process

How it works.

  1. 01

    Clear the backup

    If sewage is backing up, we open the line first so you can use the plumbing again.

  2. 02

    Camera the line

    We run a camera through the sewer and show you exactly what's in it and where.

  3. 03

    Options and price

    Cleaning, a spot repair, or replacement: you get the options with flat prices.

  4. 04

    Repair and verify

    We do the work, then run the camera or water again to prove the line flows.

Why it matters

Done right, the first time.

See it yourself

Camera footage takes the guesswork out of sewer decisions, for you and for us.

Right-sized fix

Many problems need cleaning or one section repaired, not a whole new line.

Avoid backups

Roots and grease build up slowly. Catching them early prevents a sewage backup into the house.

Buy with confidence

A pre-purchase sewer scope can reveal an expensive problem before you close on a home.

Pricing

What does sewer lines cost?

Every job is different, so we quote it individually: a written flat-rate price before any work begins.

What affects the price

  • Length and depth of the line, and cleanout access
  • Cleaning versus a spot repair versus replacement
  • Roots, grease, or a collapsed or offset pipe
  • Excavation, landscaping or hardscape in the way
  • Permits and connection requirements

Members pay less: the Dam Good Defenders Club waives dispatch fees ($250 business hours, $600 after hours) and takes 10–15% off every repair. See membership

Good questions

Sewer lines FAQ.

Don't see your question? Call or text (425) 845-3535. A real person answers, 24/7.

Who is responsible for the sewer line?

In most Puget Sound cities the homeowner owns and maintains the side sewer that runs from the house to the public sewer main, often including the connection itself. Rules vary by city and sewer district, so check your local utility. On a septic system, the line to the tank is yours.

What are the signs of a sewer line problem?

Several drains slowing or backing up at once, gurgling toilets, sewage odors, water backing up into a tub or floor drain when the washer drains, or unusually green, soggy patches in the yard along the sewer line.

Do I need a sewer inspection before buying a home?

It's worth it, especially for older homes or lots with big trees. A camera inspection shows roots, sags, cracks and old pipe material before you own them, and repairs can cost thousands.
