St. Matthews Plumbing is a five-star company. They're really responsive to my calls. I've used them in the past and I continue to go back to them. Their technicians do a lot of troubleshooting. This time, the issue wasn't what I thought it was. The plumber took the time to talk to me using appropriate language that I could understand. No technical jargon or complicated details that might go over my head. I'm not a plumber and I appreciate the plain explanation. He was very patient with me. He identified the problem and said it isn't a plumbing problem at all. It is most likely a caulking issue and cosmetic in nature. So I still need a fix but it's not a plumbing problem. I'm happy with the great service from St. Matthews Plumbing. Their plumbers are great guys.
