    "I had a break in my water main, leaking about a half-gallon per minute (720 gallons/day). By the time the water company inspector left, it was almost noon and I still had to find a plumber. Do It Right Plumbers scheduled me for immediate service, and Dakota was at my home that same afternoon. He restored the water service to my home, while bypassing the water main. This stopped the leak and allowed me and my family to go on with our day as if there was no water main problem. He explained my options and gave me exact prices. A lot of digging was needed, there were complications, and extra labor and hours were needed because the burst pipe was underneath the sidewalk. All of the dirt was shoveled on to protective tarps. When the water needed to be shut off, the down times were really brief. When everything was done, Dakota had not only replaced the water main, but also the water pressure regulator, the hose faucet, and all of the connections and valves. Then he replaced all of the dirt, re-planted the shrubs that had been removed during the job, and left the area looking as if nothing had happened. As for the final price, it was very fair, and exactly as he had quoted---not a penny more! I had a water main break before, and I remember how disruptive, expensive and stressful the last job was. Dakota really took a lot of the pain out of this latest ordeal. As hard as Dakota worked on the job, he worked equally hard to make this job as easy on me and my family as possible. If any future plumbing needs arise, I will be calling Do It Right Plumbers."

    "Herb was very thorough and made recommendations for the replacement of my faucet . He did not pressure me to do any of the work and discussed options. It was very clear he was working to prevent future issues (leaks) and brought the connections to the industry standard so I no longer needed connectors from 1/2 to 3/8 for the water lines. The job was much more difficult than I thought which made the agreed price even more reasonable. A skilled man, a fair price, and a great job (I don't have a web of water lines under my sink and the shut off valves are much more efficient)."
