Anthony T showed up on time and was very courteous and professional. He was able to fix our issue and gave great recommendations on how to avoid future clogs without damaging our old pipes with caustic drain cleaners. I'm very satisfied with the service we received and appreciate the quality and timeliness of Anthony's work.
