"I needed a part replaced on my water heater due to some leaking. Rob came out quickly and was able to fix the issue within 30 minutes. He was incredibly knowledgeable and gave me a breakdown of how the parts work which was nice to know. Pricing is very reasonable and aligns well with other competitors. I will be using RJS for future servicing needs moving forward."

Customers say: Quick response

"A pipe burst on our third floor. The water went downstairs thru the two lower levels and ruined the kitchen and bathroom and also caused a lot of damage in the laundry room. Anthony and Mark were polished and professional and gave us the kitchen and bathroom of our dreams. We were able to remain within budget, while choosing an updated look. Anthony and Mark were professional and have a great sense of humor. They did great work and we had a lot of laughs too. You will LOVE the work that they do and will end up calling them back for other projects!!"

"Outstandingly! The installer from Orbit, a young man name JOHN did an outstanding job of installing, providing helpful information, and providing and extra service which required repair of a leak in the main water line coming into the house. Great job of coordinating with the American Water Company worker to manage water shut-off and turn-on. I can't thank Orbit enough for sending JOHN to install my system. Anyone receiving his services in the future is in for a treat. John deserves a "Beyond the Zone" (Military personnel will understand that terminology) pay raise he is well worth retaining as a skilled technician and one H***-of-a-nice person, a great public relations entity for ORBIT!"

"The install could not have gone better. The technician was at my home at exactly the time given. My water heater is in a carpeted hall way and the technician was careful and considerate to ensure that carpet was not damaged. The installation took about 2 hours and when done, I would never have known the technician was in the home except that I now had hot water."
