The man that came out was quick and very respectful and the price was reasonable.

“BEWARE!! This nightmare of a company came to my house on 2 consecutive days to fix a leak. I paid them the 1st day, even though the plumbers didn't have a snake to unclog the line. (What kind of plumbers don't carry a snake to a home with a leak.) The next day a different plumber came to snake the washing machine line and said everything was all fixed. Whew was he wrong!! Later, I washed a load of clothes and heard …”

“Rob provided excellent service. I needed a new water maker shut-off valve installed. Rob evaluated the situation and provided me with solutions. The work was done quickly and cleanly. Rob also provided me with knowledge about my home and gave me some ideas and suggestions. Very satisfied.”
“Rob Richter from Prime Plumbing came to install our dishwasher when Home Depot bailed on us due to finding (older style) push pull valves under our sink. Rob came and upgraded all our valves for the price of one and then installed our dishwasher. He also hauled our old dishwasher away for no extra charge! Rob stayed with us for several hours making sure the fitting was correct, checked for leaks, and even helped sus …”
