“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! ”

“This place rocks! I have replaced two parts for an old Gerber faucet in the laundry tub. After the spout was leaking, I could not find the right washers anywhere. I had to replace the whole spout, which they had in stock, and it was priced competitively. Now, not a drop leaks. ”
