Providing Comfort to Families for over 120 Years

The plumber and electrician they sent were knowledgeable, professional, and equally as important, full of integrity. While they presented various options, they did not try to sell me something that I did not need. I would highly recommend them, the company has come a long way and I appreciate the service men they sent.

The technician helped me with my water heater. He researched the part that is needed, order it and I truly hope to see him again on the install soon. He was very knowledgeable and extremely helpful!!!

I have used John C. Flood for plumbing issues 3 times now. Each time, they're very responsive and reasonably priced. Each time, my technician has been Harry Hudson. He has done excellent work for me. Highly recommend the company and the technician!

I had an issue at my rental property over the weekend. John C Flood is a life saver! They sent someone out right away and he was knowledgeable, friendly and worked quickly for our guests. I will be using them again.

I cannot speak highly enough of John C. Flood and specifically Dale Jr. He has repaired my system twice in a moment of crisis and has gone above and beyond to make sure we are happy with the outcome. He takes the time to explain the situation and lays out all the options and processes so clearly so I feel comfortable with what he is doing. The company is excellent at sending people in a timely matter.
