 Trustindex verifies that the original source of the review is Google. Today it was Henry’s turn to save the day! We discovered after an appraisal that we needed to have earthquake straps attached to our water heater, and he came out within 24 business hours and took care of everything we needed. He did it with a smile, and he did it with excellent customer service. We are never going to call anyone else with plumbing issues - this company surpasses all of our wildest dreams of amazingness!  Before and after photos attached!! The whole thing took about 40 minutes from hello to goodbye!

 Trustindex verifies that the original source of the review is Google. We've been Bob Oates customers for a few years, and today Konrad provided excellent service locating a water leak in our home. He is a great communicator and I learned a lot as he described his approach to identifying and solving our problem. Also, even though he had to cut into our wall, he did it in a way that makes it easier for us to repair. It's nice to have a reliable go-to person to call on when we need plumbing help. Update: we had Konrad back last week to replace a faucet, and he's still doing great work! Thank you, Konrad!

 Trustindex verifies that the original source of the review is Google. Highly recommended. I had 3 companies come out to give me a quote for preventative clearing of outdoor drain lines. Mike from Bob Oates was the only one who actually opened the drain covers and used a camera to give me a fair assessment of what needed to be addressed, what considerations and complications there might be, and a realistic price quote. Other companies sent more of a salesperson with quotes of thousands of dollars to clear drain lines that they weren't even sure needed to be cleared or could be addressed through the methods quoted. Mike from Bob Oates was knowledgeable, helpful and trustworthy where other companies felt like they were just trying to sell me something.

The polite, patient receptionist got me an appointment in one day even though I knew they had no openings.   Henry was on time and completed the work in less than an hour.   On top of that he is a nice guy to be around.

Prescott was a great project manager and kept us updated and informed the entire process. We're so glad we contacted them first!

What Happens When Drain Cleaning Is Neglected?

By Bob Oates | September 23, 2026

Your drains handle wastewater every day, and normal use gradually leaves grease, food particles, hair, soap residue, and other material behind. Without occasional drain cleaning, that buildup accumulates, restricts water flow, and makes drainage problems increasingly difficult to ignore. Neglecting drain cleaning doesn’t mean every plumbing system will develop the same problem on the same…

Recurring Clogs and Their Causes

By Bob Oates | September 22, 2026

Clearing a clogged drain is one thing. Having the same drain clog again a few weeks later is another. A recurring clog often means that the original blockage wasn’t completely removed — or that another problem inside the drain or sewer line is causing it to return. Instead of repeatedly treating the symptom, identifying the…

What Counts as a Plumbing Emergency?

By Bob Oates | September 12, 2026

A dripping faucet probably doesn’t require a plumber in the middle of the night. Water pouring from a burst pipe certainly does. But plenty of plumbing problems fall somewhere in between. When something suddenly goes wrong, homeowners often have to make a quick decision: Can this wait until tomorrow, or do I need an emergency…
