WHAT OUR CUSTOMERS SAY…

“Fantastic! I walked in with parts to the faucet in my vintage sink and walked out with everything I needed. Chain hardware stores suggested I get a whole new sink and/or would not be able to do it without a plumber. The employee at Noels took a quick look, knew what it was, and had it in stock. I was able to fix my sink in two minutes with their help! ”

WHAT OUR CUSTOMERS SAY…

“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! ”
