Super service

I don't share opinions often when it comes to service so it has to be pretty good in order to get me to take the time to write something. Let me say I am extremely pleased with the service I got from Toby. He was prompt, courteous, knowledgeable and went above and beyond when it came to my service situation. I would recommend him personally and his company Imperial Plumbing wholeheartedly to anyone in this area. My broken water heater and the resultant upgrades to bring me in line with code happened promptly. No hot water makes for a pretty bad day in my opinion. Thanks Toby, you made it much easier!

Excellent in all ways

Jay called to let me know he was coming. Arrived exactly when scheduled and as confirmed by his call. Worked tirelessly all afternoon in the heat! Gave honest assessment of situation and did not try to take advantage of my lack of knowledge about the water system. Was polite and well spoken. Couldn't have asked for a better experience! Very highly recommend without reservation.
