WHAT OUR CUSTOMERS SAY…

“After trying all over my area, I couldn't find the part for the faucet in my older house. The part I needed was found on the first try on their website and ordering was very easy. It was after hours, but someone responded to my text right away. The part was shipped the next business day. After putting the new part in the faucet works better than it has for years! ”

WHAT OUR CUSTOMERS SAY…

“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! ”
