I called Dad's Plumbing and left a message one evening. They called back early the next morning, and arrived later the same day. Three plumbers arrived promptly. All were very personable and professional. They checked my plumbing stack in the basement, unclogged my kitchen sink, and checked my pipes 70 ft out to ensure no future problems. They also guarantee their work, so no worries for me. They explained their findings, and made suggestions for the future. I am keeping their business card, and highly recommend them to others.
