I have now used plumbing kings twice and both times they were on time, very knowledgeable, kept you informed on what they were doing, and their prices were very reasonable. I am a Navy veteran and was given a military discount. The first time they came out last july when my main line was backed up. I first called another plumbing company who could not fix the problem. I spoke to my best friend in southern calif who owns Timberwolff Construction and mentioned Plumbing kings to me, so I googled them and called them out. They not only cleaned out my line, but also ran the camera and found out the problem. They then came out again 2 days later and water blasted my main line with 4000 psi which cleaned out the line and made it look like new. I would highly recommend these guys to come out to your home or business.
