Frequently asked
Is $850 a fair price for sewer line hydro jetting in Washington?
Yes. $850 is right around what most homeowners in Washington pay. Anything from $252 to $1,870 is inside the normal range for a licensed plumber; above $1,870 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Line length and severity of the buildup or root intrusion. Access through an existing cleanout versus installing one. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.
When should I get a second quote?
Any time a quote lands above $1,870, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
