“Noel's Plumbing Supply found this place on Google maps. In and out service. The person I was speaking to the desk offered me a selection knew exactly what I needed price was really reasonable. You don't know how much it means to a homeowner to be able to come in without any run around trying to sell you something you don't need. I recommend this establishment to all my family and friends. ”

“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++++++ ”
