chat iconWHAT OUR CUSTOMERS SAY…

“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! ”
