They came out a fix the pipe in my rental that was causing the kitchen sink to run slow. They even took the time to look at the main line to make sure everything was okay before leaving. The price was reasonable and they explained everything and sent photos to me as well before and after the work was completed.

I want to give a huge shoutout to Sierra Line Plumbling! I had a water heater that was going out and contacted them to have it replaced. They got in contact with me right away and got everything set up. The day of installation they called and said they could show up earlier than scheduled. Installation was quick. Everyone was very professional and they even hauled away the old one for free. Very good price for the work they do and it included a 1 year warranty on labor.

Details: Yes, the location has an existing heater • Gas tank (standard) • I already purchased the water heater • House
