"My hot water heater went out. I called several plumbers and was being quoted astronomical amounts along with quite a wait time to get to me. Brice was able to get the job done quickly (since no hot water sucks) and at a price I could live with. He was super funny and professional and made me feel like a friend had come over to help. I will always call him first for any of my plumbing needs "
