"Neo was excellent! My water heater went and a new one was installed by Neo and his team the next day. They were very professional, communicated instantly, and did a fantastic job. Will definitely use S.S Piping n Heat for all of my future plumbing and heating needs. Would recommend this company to anyone!"

"Excellent workmanship and very fair prices. The faucet install required removal of an old faucet from a pedestal sink, the whole thing had to be taken apart and re-installed carefully; Joe (and Kyle/apprentice) did a tremendous job. They also fixed a leaking drain pipe from the bathtub, replaced a pressure gauge, capped a gas line, fixed 3 leaking valves, and replaced my old water booster pump with a new pump that required a slightly different hook up; all done with quality and professionalism. I waited a few weeks for this work, but it was worth it; plumbers, electricians are very busy right now. Joe was also right up-front with his schedule, which was good to know from the start. I highly recommend Buresh Plumbing to anyone needing plumbing work done- great quality work at very fair prices- Thank you!"

"Hello, Yellow Dog Home Services was phenomenal! Jeffrey was able to come the same day, complete an assessment, and define the next steps for the installation of a new hot water heater the following day. He is very personable, professional, knowledgeable and affordable. Yellow Dog is now saved in my iPhone for future project needs! Richard"
