“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++++++ ”

“This place is amazing. I live in San Antonio, Texas and there are a few plumbing stores with vintage parts but they never have what I need and the ordering process takes them weeks. I found a rare part at Noels by reverse image search but they will do it for you. I've used them 3 times. Their agents are knowledgable and polite. They will find you the same part or the after market part and get you going on your way. They have 2-3 day shipping. My house was built in the 30's and they know exactly what the after market parts are that I need. I save money and time going to them. I sure wish they were in San Antonio! I will just go directly to Noel's next time - they are LEGENDS! ”
