“I was at my witts end with a 39 year old American Standard faucet. It had been leaking for many, many months so I contacted American Standard. They referred me to Noel’s Plumbing. My faucet would not have been able to be replaced without removing the whole tub. They immediately contacted me and told me what to do. They stayed with me the whole time till I found the problem although they didn’t get a sale out of me they did fix my problem no more leaky faucet, I have them in my contacts now and will use them anytime I have a plumbing problem. Thank you Noels Plumbing for the best service I’ve ever had!! ”
