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!!
