Since
1986

We opened as Loyal Mechanical in the Loyal Heights and Ballard neighborhoods. Founder Brian Larson grew up in Ballard and graduated from Ballard High School. In 1991 we acquired Pioneer Plumbing and expanded into service plumbing.

Four decades later we're still family-run, still local, still guided by one line: exceptional service and quality work at a great value.

How do you price a job?

Flat, written price before we start. We diagnose, quote one number, and it doesn't move unless the scope changes — and then we tell you first.

Do you charge to come out?

There's a service-call fee for diagnosis, credited toward the repair if you go ahead. Sample: $XX (Sample).

What are the signs my sewer line is failing?

Multiple slow drains, gurgling toilets, sewage smells, or soggy spots in the yard. Any one of those deserves a camera inspection.
