“I have come here as a maintenance technician countless times. NOT ONCE did these guys fail to impress me with their knowledge. They are across town for me and I don’t complain due to their unmatched service. I can bring in a busted chewed up cartridge or part and within 10 seconds the guys are like “ yup we have one right over here” and will bring me the exact match from what I had. Simply top tier. -SNS management ”

“I was very happy with Noel’s Plumbing. I was searching for a fairly rare part and saw it listed on their website. After placing my order, I was informed that the item was actually on backorder. Noel’s Plumbing was upfront and honest right away, letting me know it might take some time to arrive. Throughout the wait, they consistently kept me updated, which I really appreciated. When the part finally came in, they shipped it out immediately. It arrived exactly as described and was precisely what I needed. Excellent communication, honesty, and follow-through. Thank you, Noel’s Plumbing! ”
