Had some gas lines run and Dylan did an excellent job. Jeremy returned initial referral contact call quickly and was very friendly and responsive. Dylan was on time, efficient and professional. Service pricing was excellent and we were extremely pleased with Advocate Plumbing and would highly recommend the company! Had a shower leak repair done a year later and again received excellent customer care and service.

We recently engaged Advocate Plumbing Company to complete the rough-in plumbing for our new master bathroom shower. From the initial consultation to the final cleanup, the entire process was seamless. Zach R. was prompt, courteous, and demonstrated exceptional craftsmanship. He took the time to walk us through the work and ensured everything was perfectly up to code. A truly professional and reliable service—we couldn’t be happier with the result and would highly recommend Advocate Plumbing to anyone for all of their plumbing needs.

We had a great experience with Brian from Advocate Plumbing. He came out and gave us individual price estimates. We had a new diswasher installed, a water heater flush, and a couple of pipe valves replaced. The price charged seemed quite reasonable for the amount of work involved. The work was done quickly and efficiently. Brian also performed some routine maintenance and verified our water presure and water hardness level for free. That was much appreciated!

We’ve worked with Advocate Plumbing twice now (once for a tankless water heater installation and an RO system install) and are incredible! They are reliable, professional, and very knowledgeable in their work. Each time they’ve come out to the house they are friendly and respectful of the property, prompt in their work and very honest of their assessments of the house and the work that needs done. We would highly recommend them for any plumbing needs!!

I had a great experience with Advocate Plumbing. My house is over 100 years old with a lot of weird plumbing and Brian did a great job. I had my water heater flushed and some other small but needed replacements done. Brian was friendly, efficient, and knowledgeable. I would absolutely recommend them to others and I would use them again in the future.

Jeremy the owner is a stand-up guy. He obviously cares about doing a good job, and that culture is reflected with his employees as well. He is knowledgeable and honest and I would recommend Advocate to any of my friends and family who needs a plumber.

I saw water bubbling up between our meter pit and the house. A friend recommended Advocate Plumbing. Jeremy sent a tech out immediately to confirm the break, gave me a quote, and scheduled the work for the next morning. The crew arrived on time and completed the line replacement and interior work in less than 7 hours. They were all professional and polite. They cleaned up after and minimized damage to the yard. Like my friend, I will not hesitate to recommend Advocate Plumbing to anyone.
