"Experienced Staff! Raymond over the phone was amazing! The plumber that came to my house was Rick, highly recommend him! I had a water filtration and tankless water heater installed by this company and couldnâ t be happier with it. This was the second time iâ ve used this company , The first time was for a 3rd opinion on my hot water leak under the slab. Two well known large companyâ s in OC wanted to charge me $24,000-$31,000 for a repipe with no other options and said i had multiple leaks without pulling out a single tool!! Had this company out and right away Rick preformed a ultrasonic leak detection and found my leak (Only one i actually had) and provided me with a quote for a reroute of the hot water line and a quote for a repipe. Price was Very fair and saved me tens of thousands. Me, my family and friends will use this company for all of our needs going forward."

"This was a tough decision for me to spend a lot of money to fix my seeer line. But the people at Mother Modern made me glad I did this, that I chose them. Tyler was top notch and Jerry was the best plumber I have ever hired and the excavation crew were the best."

"We hired them because we wanted to see if we could purchase an inhome ice maker and needed a plumber to see if the waterline would work. The tech was honest and told us that in order to install the icemaker we would have to break building codes, which he would not do nor recommend we do. He was thorough, professional and friendly."
