"The gentlemen was very friendly and helpful. I had previously accidentally ran over the vent pipe breaking the top off and leaving a ring inside the pipe. He kindly removed it for me at no cost. They seemed to do a good job emptying the septic tank even having us flush the toilets to make sure everything was draining properly. All in all I would recommend Mr. Rooter, who was able to come the day after I called."

"Removed old water heater and installed new water heater and brought water heater up to code. They arrived on time and performed the work efficiently and neatly. The price for the direct vent water heater plus installation was about $250 less than another local quote. Overall I am very satisfied with the price and quality of the installation."

"The technicians are amazing at Ethical Plumbing. My mother passed away and the next week I found a water leak in her basement. I called Ethical Plumbing and they got me on the schedule the very next day and made everything so easy. We have since found a different problem that they also helped us with. Always shows up on time and diagnoses the problem and offers different solutions. Thank you!"

"Stephen was great, my tub backed up with water and my toilet would not flush, turns out my septic field needed replacing. Very responsive, reasonably priced and best of all. I didn’t have to leave my home during the repairs. I’d give 10 stars if I could."

"We had another plumbing company come out due to a leak. Rather than do any diagnostics, they just replaced the pressure valve. It still leaked. I called the next Monday and was told oh, you need a new water heater. Johnny Gavilan from Preferred Home Services checked a couple things and found our expansion tank was bad. He did warn us there still could be a problem with the water heater but at least he checked first. If we need the water heater replaced, our expansion tank will be new!"
