Who is responsible for the line out to the street?

In most cases the property owner owns the lateral from the house all the way to the connection at the main, which surprises people. Responsibility does vary by jurisdiction, so we confirm with the city before any work starts.

Do you offer trenchless replacement?

It depends on the line. Trenchless methods need the existing pipe intact enough to work with, so we camera the lateral first and tell you honestly whether it is a candidate or whether an open trench is the sounder option.

What happens to my yard or driveway?

We talk through the route and what has to be opened before we start, so there are no surprises. Restoring the ground is part of the job, though matching finished surfaces like stamped concrete may need a specialist.

How long does a replacement take?

The dig itself is often a day or two for a typical residential run. Permitting and inspection scheduling usually decide the overall timeline more than the digging does.

Will the city need to inspect the work?

Yes. Lateral work is permit work and gets inspected. We pull the permit and meet the inspector as part of what we quote you.

Alexandra replaced the waterline from the meter to my house and under the house too. She did it all in one day and at a very fair price. No more leaks! I am very happy I used Northwest Plumbing Solutions and will be calling her back for more work soon. I highly recommend Alex.

My hot water heater fizzled on me Saturday and I called this morning. Christina said Alex could come out today, which was great. She checked out what was wrong and said she could replace it today. Which she did. I was impressed how she got the work done. And I got hot water! Yay! I will Definitely use them in the future, and I will refer them to friends and family. Great to support a local woman owned an operated business.

Alex and the team at Northwest Plumbing are outstanding. We had an emergency with a significant leak on our side of the city water main, discovered first thing the morning by city crews. I reached out to Northwest via their web interface, and Alex and her office team both called back within an hour and a half. She had availability (thankfully!) in the afternoon, and we were fully fixed and back up before 3 PM - amazing. The project also came in squarely within her estimate range at a very fair price, especially for short-notice work. The little things also really mattered - they send text updates when they are en route, when the service is active and complete, and also sent pictures with the invoice via email of the repair before and after the work. It was refreshing to have all of this customer-facing communication. Overall the customer service experience on top of the actual high-quality plumbing service was fantastic. The fact that they are local and woman-owned is also a great bonus.
