I have had to call King out for two minor emergencies over the past few years. The most recent time was a Friday night, not during business hours. John had his employee Scott on scene within an hour and the issue was resolved within an hour upon his arrival. I have dealt with Scott twice and he is extremely professional and friendly. I was expecting to be raked over the coals for the last repair due to the late hour, but was pleasantly surprised when the price came to what I’d expect for a non-emergency repair. If you are searching for a plumber, stop your search and call these guys. Small town service like this doesn’t exist anymore.
I have had John for several jobs. The big one was putting in a new water pump. He & his team go over and above what they need to do to make sure the job is done to perfection. He listens and understands just what the customer needs and wants. I would highly recommend him.
John came by to give my husband and I an estimate on some heating and plumbing work in our home. He is by far the most professional person I have ever had the pleasure of meeting. Not only can you tell he is honest, he makes sure to put all that important information right on his business card. He also makes sure to hand it to you right away. I'm looking forward to John fixing our heating and plumbing issues.
They were awesome! Fast and friendly
John and his crew have a professionalism and attention to detail that you can only find in a small family owned business. After being a customer for over 20 years I find no reason to change.
