"My gas water heater was 12 yrs old and needed to be replaced. Since I had prior experience with Mr. Rooter installing a water filter under my sink, I felt confident that the job would be done professionally. Rohan and Derick did an excellent installation of the Water Heater. The office was excellent too in informing me of their arrival time. I high recommend Mr. Rooter."

"Every time it would rain the side of my yard would flood and get into my house. A close friend recommended Napolitano Brothers Contracting. Jim, James, and Michael Napolitano were great to work with. They installed a exterior drainage system and also water proofed the side of my house. After, I hired them to do a paver patio and driveway, both of which I constantly get compliments. I am glad to have found them!"
