About Us

Owner and founder Sean Doncaster started Precision Plumbing & Supply back in 1999, and has been running the family-owned and operated business ever since. Sean brought years of experience with him to the table when creating the company, and now has three additional employees as well. Between them, they have enough professional experience to tackle any job. However, what truly sets this business apart from any other is the dedication first and foremost to helping people with homes – even if that means repairing a furnace at 11pm for a family without heat.

When it comes to residential and commercial plumbing services, as well as fixture and parts supply, there is no one else better in Richland, WA or all of the Tri-Cities area. We currently hold an A+ with the BBB, are a member of the Home Builders Association of Tri-Cities, and have a “Preferred” rating on Angie’s List. But what makes us the most proud is the number of our jobs that are from repeat customers. This just goes to show that we did the job right the first time, and they trust us to do so again. Our customers have told us that our response rate is outstanding, and our reliability unparalleled – just send us an email or give us a call, we’ll set up a time, and when we say we’ll be there… we’ll be there. It’s as simple as that!
