About 100% Plumbing

35 Years. Same Faces. Same Standards.

We're not a call center or a franchise. We're a family-owned plumbing company built on 35 years of hands-on experience serving Peoria and the Northwest Valley — and most of our team has been here for years.

From the Owner

I've Been Doing This a Long Time — And I Still Show Up

I've been a plumber in the Northwest Valley for 35 years. In 2016, I started 100% Plumbing with one truck and a pretty simple idea — show up when you say you will, do the job right, and treat people the way you'd want to be treated in your own home. That's still the whole business model.

We're based in Peoria. We work in Peoria, Surprise, Sun City, Sun City West, and the communities around them. These are our neighbors — people we've been fixing pipes for across multiple generations of the same family. That means something to us.

When you call 100% Plumbing, a real person answers. Not a machine, not an answering service — someone on our team who can schedule your service, answer your questions, and get you taken care of. We show up the same day on most calls, we tell you what's going on before we do anything, and we back every job with a 2-year labor warranty.

I'm proud of the team we've built. McKinley has been with me for 15 years. Tim has been our head technician for 6. These aren't just employees — they know this work and they care about doing it right.

If you've got a plumbing problem in the Northwest Valley, we'd be glad to help.
