"⭐⭐⭐⭐⭐ Water Heater SOS was a lifesaver! When our water heater broke down, they responded quickly, diagnosed the issue, and had it fixed the same day. The technician was professional, knowledgeable, and took the time to explain everything clearly. Pricing was fair, and the service was top-notch. I highly recommend Water Heater SOS for anyone needing fast, reliable water heater repairs!"

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."
