chat iconWHAT OUR CUSTOMERS SAY…

“It is so nice to see you guys are still rocking and providing the best service for unique plumbing parts. I first used you guys 20 plus years ago when my brother turned me on to you. I live in Nashville now and was searching the entire region for a particular cartridge and you are the only one that had it. Hands down there's not many like you and you've always provided a great service and I'm glad to see you doing it now even online! ”

“Y'all are amazing. I live in Texas and it's faster to order express from Noel's than go to local parts stores. Customers can text Noel's a picture of the part they need and Noel's will find that part or the equivalent and text the link. They have 2-3 day shipping available. The staff answers the phone quickly, politely and they know their stuff! The unit I needed plumbing parts for was built in the 30s. No matter, Noels has me covered. I highly recommend them. Thank you Noel's for your efficient, old school excellence combined with current technology! You have saved me so much time, money, and aggravation! A++++++ ”
