We recently had a water softener installed, and the entire experience with Advocate Plumbing was outstanding. From start to finish, the professionalism was clear. They arrived on time, communicated every step of the process, and made sure we understood how the system worked before they left.

The installation itself was clean, efficient, and clearly done with care. They treated our home respectfully, kept the workspace tidy, and double checked everything to ensure the system was running perfectly. It’s rare to find a company who combines skill, courtesy, and genuine pride in their work—Brian and Vance absolutely did.

Our water softener is working beautifully, and the whole experience was smooth and stress free. We highly recommend Advocate Plumbing to anyone looking for quality plumbing work and true professionalism.

p.s. They also flushed out our hot water tank while they were here…and checked all of our plumbing fittings throughout our home.

They did a fantastic job...in most cases without me being there. I had wanted a tankless water softener. I am very glad I reached out to these experts as I saved having to replace a tankless because it would not be sufficient to treat minerals, etc., in my area. I also have a duo system that better filters my shower and tap water as well.

Dylan attached home gas line to new grill. He took time to explain what needed to be done and gave us a price. Reasonable cost. He also checked water pressure and water softener. Thank you Dylan.

Outstanding response, we had water all over our utility room now that there really wasn’t a problem. It was an overflow deal with clogged inspected everything and no charge. Can’t beat that.

Was able to make a quick call, get an answer for the service needed, taking multiple options into consideration. Technician let me know when they would arrive, making it easy on my schedule, and also tested and checked other important plumbing items in the house to make sure they were all in good shape. Install went well and quickly, and couldn't be happier. Thanks Advocate!

I had a water leak and was recommended to Advocate Plumbing. Brian came out and found the leak, fixed it and even took care of a couple other issues I asked about. He was great to work with, answered all my questions and explained exactly what needed to be done. The price was very reasonable and the work was excellent. I highly recommend Advocate Plumbing.

I recently had Advocate Plumbing replace my water heater and couldn't be happier with the experience. From the first call to the final install, their team was professional, knowledgeable, and easy to work with. The technician walked me through exactly what needed to be done, gave me a clear and fair quote upfront with no surprise charges, and completed the water heater replacement efficiently. They cleaned up thoroughly before leaving and took care of the old unit too.

Brian came out to check an outside faucet- only needed a little tweak. Then flushed our tankless water heater and set up a condensation filter. Wonderful company. Excellent customer service. Outstanding communication, even days after Jeremy was happy to answer my questions. I will call them anytime I need a plumber 👍😁

Brian did excellent work. He replaced a broken garbage disposal, fixed a leak on an outdoor spigot, and took the time to walk me through the condition of other fittings around the house.What stood out was his approach. No pressure, just clear information so I could make informed decisions. He pointed out areas that might need attention down the road and explained what to watch for if I chose not to address them now.It is not easy to find someone you trust for home repairs, but Brian earned that. As my house gets older, I feel confident calling him for future plumbing needs.

We had several plumbing issues and they were local and when i called them somebody answered right away. Set an appt to come out next day. The plumber was prompt and on time and very courteous and sincere. Included my husband per my request and communication was great. The estimate price was fair for all the work done. We bought our own faucets and they knew exactly what to do. Everybody was on the same page and the plumber was very knowledgable and ansered all my questions and did a great job, got everything working perfectly. I would definitely recommend them for your plumbing needs because they seem to care about their customers.

We have used Advocate Plumbing multiple times over the last couple of years. Once for a drain issue, another for a sump pump line repair and then again for a hot water replacement. Every time they have been quick to schedule service. The most recent time I was able to schedule online an appointment for next day service. They are knowledgeable and friendly. They clean up after themselves and have fair pricing. I appreciate that Jeremy the owner calls and explains the estimates before any repairs are done. We will definitely continue using them!
