“These people were extremely helpful in taking me through replacing a 25 year old hard water frozen cartridge on my Philrich sink faucet. They were able to identify the correct part I needed from a photo I sent (I had it figured out wrong). I was pleasantly surprised they had an obscure part like this, but they also told me how to extract the old one when I couldn’t get it out. They said to unscrew it after I had concluded from YouTube the old cartridge was supposed to just slide out. It threaded out as they said and saved me buying a cartridge extractor and a hernia. The whole experience has been excellent. ”

“Hello, I was in the shop on Tuesday and was greeted and helped by a gentleman named Jackson. He was extremely helpful, friendly and it was really a pleasure to see a young man working in this industry with knowledge and kindness. I run my my own small business and was a first time customer at Noel’s, being greeted and cared for in that manner will definitely bring about my return. I want to send me sincerest gratitude to your team. Thanks again! ”
