“Prompt, professional and expert service”

Prompt, professional and expert service. Very impressed with their responsiveness to emergent issues. I’ve had a few issues (new hot water heater and bath tub drain in need of repair) and they were available to help almost immediately. Prices were fair and the work was top notch. Highly recommend!

Professionalism, Punctuality,  Quality, Responsiveness

Port City Plumbing is excellent. We had an emergency plumbing issue and they immediately responded and were able to send two people right away. Tim and Shane were excellent, professional, and efficient, they found the source of our leak and fixed it right then and there. We are very grateful for them! Thank you guys so much for your help!!

“Friendly, dressed professionally and wore a smile the whole time”

When we moved into our new store location, the toilet was broken. The handle had snapped and the gasket worn through. I called up Port City and Leanne answered right away with a calm, friendly voice. She made an appointment for the next morning. Joe arrived ready with tools in hand. Our toilet was fixed in under 30 minutes. Friendly, dressed professionally and wore a smile the whole time
