"He came when he said he would and installed two ceiling fans, replaced two light switches, repaired my basement door, and installed two plant holder brackets in the ceiling. He was a pleasure to work with and I was extremely pleased with his work. His prices were very reasonable for all the work he did. I would definitely recommend him to my friends and I would hire him again."

"Rob and Christine are terrific. Christine handled the appointment and communications until Rob was onsite. I found Rob to be very knowledgeable and professional. He pumped the cesspool and then used a digital camera to check inside the cesspool to determine type. Afterward he applied the chemicals. Unfortunately we don't have an overfill pool so we have to pump our cesspool more frequently. Rob explained in detail the process, cost and time to install and overfill pool and we will definitely use Mid Suffolk Cesspool when we're ready."
