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!

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.

Jeremy and his staff are amazing to deal with. We could not operate Noblesville Youth Baseball without them. Whenever we have an issue Jeremy and his staff are on it and involve us by educating us on the different solutions and options that they are suggesting to fix the issue. I really appreciate the time they take helping us understand what the problem is, what the options to fix it are, and the pros and cons of each option.
