"Friendly, knowledgeable people. Fast response. Competitive price. Same day service. Excellent installation, better than original. Ethical Plumbing was recommended by a coworker (Harold D.) and they have great reviews on Angie's List so I chose them for this job. Perfectly satisfied with the project and I highly recommend them."

"The men were thorough and efficient. The materials were high quality. The job was carried out fast, no corners were cut. My main complaint is that they had to install a dehumidifier or the encapsulation wouldn't work. It runs 24 hours a day which impacts our electric bill."

"Water pressure was too high causing an awful noise when toilets flushed and faucets running. Called Angi's list t I find a plumber for an estimate. 5 choices came up. Johnson Brothers was the first on the list. Called and Jacob responded immediately. He was able to come over, access the issue and repair all in the same day. Some sort of pressure valve was needed. Jacob explained every step, as if he were a surgeon explaining the procedure. He checked for leaks, there were none. Finished the procedure and no more awful noise. Plumbing issue solved all in a few hours. Very professional I every way. Highly recommend as far as work done right. Price was reasonable I suppose. But worth the no worry mentality."
