“Hey these guys are awesome! If you need a part for a fixture they have it send a picture and they can tell you what it is, they know their stuff, they have the weird obscure things you can't find unless you get a whole trim kit or whatever. Worth the trip and the money. They save you tons of time definitely visit ”

“The cartridge in my kitchen sink broke last week so I've been without that sink for a whole week. I ordered a replacement from Noel's, which I could not find anywhere else and it worked perfectly. Thank you! You saved me! ”
