“Gabriel was very professional. He was friendly, left everything clean, he was also trying to be quiet with the tools when I was on the phone in the next room.
The price seemed high, but he at least made me feel like I was getting better service for it.”

“I have been a customer for 5 years now. This company is excellent. They make sure the job is done right. Their workmen are competent, knowledgeable, and courteous. When I have an issue with plumbing, the air conditioning equipment they installed, or anything else in my home, it is Joseph Frederick and Sons that I call. Thank you all!”

“I was impressed with John Ratcliffe. He listened attentively to me explaining our situation and offered various possible causes and fixes. All things considered, he assured me that our heater would be repaired that very evening. That was what I, as the customer, wanted to hear. Kudos to John!
Olaf arrived and introduced himself. We discussed the problem. He had been briefed and was prepared. He set to work and repaired the circulation pump and capacitor quickly. He also addressed an issue with two valves, determining that an inner washer on each had loosened. He was tidy. He also listened to what I was saying. Again, this is what I as the customer wanted.
All in all, my experience was excellent. 5 stars all the way!”

“Dennis was great!! Surely one of the best servicemen I have ever had. He replaced my 40 year old sump pump…was so efficient and knowledgeable. Because of him, I will use this company for other issues in the future.”

“Excellent customer service. Professional and courteous. Dennis came up with a great solution for the bathroom shower issue until we are ready to do a full remodel.”

“Want to compliment Lucas Kemp. He’s your first service tech to ever ask me if my radiators were all heating properly. Have owned my home since 1992 & have had furnaces serviced annually. Please pass this on to his supervisor. He was both courteous & pleasant. Hoping he does my maintenance next year.”
