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

I’m delighted with the final product, hot water from a new, professionally installed water heater. The people at Sierra Line, Jessica and Marc, are wonderful to work with. Everything from start to finish, vender/bid selection to warranty registration, went smoothly. At a very reasonable price, a new,, cleanly-installed water heater now quietly resides in the corner of our garage, doing its job.

Details: Yes, the location has an existing heater • Gas tank (standard) • I would like to discuss with the professional • House
