I was impressed with Advocate Plumbing's speed, efficiency, communication, politeness and punctuality. They arrived on time, explained what they would be doing to my gas line and completed the job on time. The team was courteous and kept me updated throughout the visit. I appreciate how organized and responsive they were, and I will call them again if needed in the future.

I had my bathrooms remodeled by people I realized are scam business people. I am a military veteran and always prefer to do business with local small businesses. I found Advocate Plumbing on the BBB website and gave them a call. I spoke with Jeremy and told him about my situation. He was very caring and had his business manager Tyler reach out to me right away to schedule for a technician to come check out the amateur work that was done. Dylan came and let me know what needed to be done to fix one of the problems. To make an extremely long story short, Dylan took care of a major problem the remodelers made in my wet areas of my bathrooms. It took longer than we all anticipated to complete repairs, due to having to order special supplies, but I am so grateful and feel more at ease with how my shower/bath faucets are working. They honored my military service and showed me respect as a female homeowner. I HIGHLY recommend Advocate Plumbing for your plumbing needs! Thanks Gentlemen!!

Jeremy Robinson, the owner, contacted me and asked if they could have one of his guys come in and look at our toilets because he could see something was wrong. He was able to go in and fix the problems. He donated his time and service.

They did some work for us out at Noblesville Babe Ruth. Work was outstanding, Jeremey and his team were very communicative throughout the entire process. They also gave us some suggestions on where we could save money and where we might have to spend a little more, but be able to save money in the future which we appreciate appreciated!!! Cannot recommend this company enough.
