"Just had my water heater replaced by these guys and honestly, they were awesome. They showed up on time and got everything done way faster than I expected. The whole team was respectful and easy to have around. They worked efficiently, cleaned up after themselves, and just made the whole experience stress-free. If you need a water heater replaced or repaired, I highly recommend these guys. I had called around a few places and Water Heater SOS was the quickest to get back to me with the best price as well. Solid work and just a great crew all around."

"Rafael came and was able to get our water heater pilot working quickly in a very professional manner. He the took extra time to go over its operation. There was no push to replace the heater which is eight years old, if I have more serious plumbing issues in the future, I will definitely call Diamond first."
