"Guy who came gave me good advice and advised that he felt my issue was not needed for repair. He didn't try to sale me any service as he saw no need. I appreciate a plumber who isn't trying to get work out of people whom don't need it."

"I highly recommend this company!!! He responded within minutes of my searching for a plumber. He came the next day and installed a new tankless water heater. He also found a faulty electrical outlet and repaired it as well. Quality workmanship. I will keep his number. His name was Harry."

"Oak Plumbing did excellent work and is very expensive. The guy, Zachary, they sent was very nice at first. He was here approximately 3to 4 hours and our bill was 2,000.00. We felt that was a bit expensive. Zachary was nice but he never pumped water through the washing machine to check if his work fixed our leak or there were other problems. Turned out a pipe was broken under the house. Zachary wanted an additional $500.00 to fix the broken pipe he missed. His personality changed when I asked him to lower the price. It was a PVC drainage pipe that needed to be replaced and the joints glued. I had to get another plumber. Zachary turned nasty, turned around, and walked away mad. He should have looked at the whole job and tested the washer after he was done. Fixing the pipes involved."

"Did an excellent job overall, Replaced the service line from meter to house. Arrived before schedule, started the job early, were very quiet and did not disturb the neighbors, or me! Had me inspect as they went along. Did not disturb existing old plumbing for our well,, or the PVC for the sprinklers. Would definitely use them again and have given another neighbor their contact info for possible future problem they are concerned about."
