"The plumber showed us a trick for how to clear the food trap using the garbage disposal and water pressure, which I really appreciated! He also, with permission, came early so punctuality was great. Only downside is this business is pretty expensive, twice at least what I have paid out prior plumber."

"Mark was very thorough in researching the system we needed to solve our water issues. I recommend him to anyone that has a water problem, as he does work hard to correct all areas of your water to give you peace of mind . Mark always showed up on time and was diligent to resolve our concerns."

"Mark & Ignacio did a great job with a temporary fix of a water main line that another big plumbing company had given up on – leaving us with no water for 4.5 days. Mark was easy to talk to, responded promptly on a Sunday night, and gave us a very fair price for the work. I would highly recommend him- he was professional, knowledgeable, and honest. Once we get the major trenching work necessary done, we will be calling Mark to lay the new water main pipe and finish the job. You can’t go wrong hiring Sierra Line Plumbing."
