Highly recommend RJ O'Neil! They replaced our water heater and were on time, efficient, professional, cleaned up after themselves, and were so friendly. Will definitely hire them again!

I hired RJ O’Neil to conduct our backflow testing on our irrigation system the past two years. They are very responsive, consistent, and professional. They arrive on time and submit the required report right to the city for you. Very polite and nice to work with. I would highly recommend.
