“Fantastic! I walked in with parts to the faucet in my vintage sink and walked out with everything I needed. Chain hardware stores suggested I get a whole new sink and/or would not be able to do it without a plumber. The employee at Noels took a quick look, knew what it was, and had it in stock. I was able to fix my sink in two minutes with their help! ”
