Owner / Operator Sean Doncaster got back to me via email per my appointment request within 24 hours of that request. He and his assistant arrived promptly and indicated what they would implement in terms of my service request. The work was completed in under the expected time and everything was in order on conclusion of the appointment. I recommend Precision Plumbing and Supply to anyone that has a need in terms of plumbing services. Cheers.

Believe it or not No one from Precision came to my home but I would call them in a heartbeat. I called them due to no water pressure. We were baffled. On the phone they helped us to find our problem. They could have easily come to our house and charged us hundreds of dollars but instead they helped us solve our problem on the phone. We spent 3 days straight repairing ourselves. Thanks Sean!

Sean and his worker showed up exactly when they said they would. Removed an old and hooked up a new dishwasher in a very short time. Ran it thru the test cycle, hauled the old one away. They're going to be coming back to install a toilet and vanity sink! Very pleasant to work with.
