"Water heater failed on a Sunday. Called Rooter just after lunch and they said they would be at my home by 4:30 to give me an estimate. Their technician got here at 4:00 and I had a new unit installed by 7:30 pm. Great work, great Technician!"

"This group was hired by repipe to repipe my house and they did an outstanding job! I am a very picky person but I was very satisfied with their work not to mention the extras that were put in to bring my house up to code as a courtesy! I rate them as five stars and would recommend them to anyone that needs work done. They were courteous and very respectful towards my premises."
