"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!"

"I had a water heater emergency on a Saturday, and my four girls were frantic with no hot water.  I called several plumbers who were not able to come out on the weekend or wanted way too much money.  When I called Steve at All about Plumbing, he was very nice and was able to come out the sameday.  He did not charge an estimate fee, gave me an estimate to fix the problem.  He installed a new heater that night and we were back in business and ready for Sunday morning showers before church.  He promised to be there at a certain time and was.  He was professional.  I would recommend to my friends and family."

"Jesse was great to work with and very knowledgeable. Pleasure to have work done. He ensured that I had no other problems with plumbing by going into the crawl space. New toilet put on and leak fixed! Affordable and will work well with you."
