I had a pre-sales inspection done where some plumbing items were called out as being in need of repair, and I contacted Advocate for a quote. Not only did they come out quickly, they got me sorted out on the same day after giving me a super reasonable price! Highly recommend!

We had a plumbing repair need in our master bathroom. The original quote from our established home service company was a discounted $2800 member price for the labor. At the recommendation of a co-worker, we contacted Advocate Plumbing. Their quote was just over $1200 (nearly 60% less)! We went with Advocate Plumbing and have no reservations recommending them. The work was performed quickly, cleanly and economically. The two plumbers required to do the job were professional and courteous. The owner contacted us during the job to ensure it was progressing as we expected and at the end of the day to ensure that we were happy with the work done. The repair is functioning flawlessly and we saved almost $1600. We will definitely use Advocate Plumbing for any future plumbing needs.

Jeremy was able to come out and install a gas line to my stove on the same day he came to give me the estimate. He was very honest and clear about the work to be done and completed in a professional manner.

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!

Advocate Plumbing was incredibly honest from start to finish. Their plumber explained the problem clearly, for a sump replacement, gave a fair estimate and never tried to upsell unnecessary work. I appreciated the transparency and would highly recommend them for any needs

I had the “pleasure” of replacing two water heaters on the same day. Normally that would make it a terrible day but the team at Advocate Plumbing were champs. New water heaters were installed in both properties before noon and everything was clean and neat when they finished. I really appreciated the explanation of why the particular units were recommended. They did make the entire process a pleasure. Thank you, Jeremy and team!

The Advocate Plumbing crew is awesome. Had them out to install two outside hose faucets with service access panels, install a new Main shutoff in the garage, install a new kitchen faucet and install a new shower faucet in our 2nd upstairs bathroom. They did a professional job and cleaned up after themselves all in about 4 hours. Advocate Plumbing were the most reasonably priced and gave me a package deal. I had a couple quotes from other companies that were outrageous and double what Advocate charged us. If you're looking for a professional plumbing company, look no further. Advocate is the best!
