“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 ”

“Just before an event, we had a 9 7/8" round drain cover snap in half. It was an odd size and Noel's was the only place that seemed to have one that would fit. We couldn't leave the hole exposed during the event, and Noel's was kind enough to make sure it was overnighted to us. Their effort was truly appreciated and the cover fit perfectly! I highly recommend them! ”
