Choosing Advocate Plumbing was a great experience all around. I had an emergency gas situation on a day when the temp was going below zero and I was going to have no heat in my home. Dylan was at my home within 45 minutes of my call to Advocate and he got things figured out quick enough that the gas company was out and had us turned back on before unlivable home conditions, frozen pipes, or other disasters occurred. Advocate not only knew what they were doing, but also cared about the welfare of me and my family.

The team did a fantastic job of identifying a drainage issue that had gone undiagnosed by the builder for over 2 years. This is what I needed to feel confident in my warrantee conversations and offered me a sense of relief that I was not overreacting in regards to the severity of the issue. Thank you!!

Loved the explanation and care they took in getting our new water softener. I had also had other companies come out and they were priced the best. Hometown business are the best and Advocate Plumbing was top notch! Thank you!

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!!
