“Great work! Diagnosed problem , ordered part, fixed the problem. Happy to have a working heater in anticipation of the cold nights ahead. Thank you!”
“Your technicians are always respectful, thorough and excellent in their service.”
“Impressive service. Same day replacement of hot water heater. Dennis did a great job. I could not be more pleased. Thank you so much.”
“Dennis was very polite, knowledgeable and professional. He was very careful to keep the house clean as possible and cleaned up any mess made. He did a very good job making sure the sewer line was clear and would stay clear. Dennis did an excellent job explaining what he was doing and that the sewer pipe was in pretty good condition considering how old it was, Dennis did a fabulous job and I would highly recommend him and Jos Frederick & Sons.”
“As always Donovan does an exceptional job. Explains changes or any problems. Friendly and informative. We request him all the time. Joseph Frederick s company from office staff to service technicians are wonderful and attentive. Great to deal with people who know and do their jobs so well.”
“The work was done efficiently & for reasonable cost + they looked at our main water line – the valve is old & hard to use. They put another valve in upline so its easy to turn the water to the house off now & its safer.”
“Don was knowledgeable, professional and friendly and determined the issue with my AC in short order. He also completed a thorough investigation of my furnace in the basement. He found no issues, but also provided me some tips and information that will come in handy in the future. While down in the basement with Don I had mentioned problems I was having with my sump pump. No problem! Without a second thought, Don went right to the sump pump, identified the problem immediately and suggested a solution. Jos. Frederick & Sons are now scheduled to replace the pump and repair a section of pipe tomorrow morning!
I bought an 80 yo home two years ago. Jos. Frederick & Sons were highly recommended by my realtor, and I am delighted with their service so far.”
“Dennis was pleasant and very skilled. He solved our problem quickly. Thanks to all the great techs that have kept our home running well. Thanks also to Sarah who got us on the schedule quickly.”
“I called this morning about a gas leak at a client's furnace. Gabriel was sent out a short time later & located the 2 small leaks & repaired them in good order.
Excellent service & excellent timing. Thank you.”
“Tim and Anthony came into my house to repair three plumbing problems. They were on time and their work was excellent.
They were efficient and courteous and go the extra mile. This is the third time they have been here for different plumbing repairs including
a new hot water heater. So now I request the 2 of them for the plumbing jobs. Also Jos Frederick & Son's have very reasonable pricing compared to other Company's.”
“Of course, Aaron did an excellent job!!!”
“Aaron was excellent! He knew exactly what the problem was just by hearing my air conditioner try to work. I now have a maintenance agreement and am very happy being with Frederick & Sons . . . thank you.”

“Thanks to Andrew and Cameron for an amazing job installing our new ceiling fans!
In the 2 years we've had this house we've had to call a ton of different contractors to get work done, but finding a good electrician in particular has been strangely challenging. We tried a few different companies and always had issues, from cleanliness to incomplete/incorrect work (and I swear, we aren't extremely picky – imagine paying to get a light switch added, and after they leave, you discover greasy finger prints all over the wall AND the light switch somehow doesn't work!!)
So it's been such a relief to finally have found someone that's reliable and professional to take care of all of our electrical work. We first called a few months ago to get an outlet installed for an electric oven, and Andrew came out, investigated, and delivered the great news that we already had the power hookups we needed and no work needed to be done. His honesty and professionalism in that scenario stood out to us, so we were eager to call again when we decided to get ceiling fans installed throughout the house. Andrew came out again, this time with Cameron, and they did an incredible job from start to finish. They were clean, efficient and professional throughout the entire process. Whenever they ran into obstacles (and this house presents many), they presented a few options to us, let us choose how they should proceed, and got right back to work. And they didn't leave a trace behind when they were done. What more could you ask for?
We're already cooking up more projects for them to come out again. Thanks fellas!”
“Dennis was professional and courteous as he always is when we need any repairs to any of our plumbing issues! This time it was a leaking kitchen faucet. He identified the issue and repaired and replaced the problem within an hour. I am always confident and satisfied that with any plumbing issues I have in my home that the guys will do the repairs correctly and fix the problem! Thanks again for a great job!”
“This was the yearly checking of my air conditioner system – want to say that the Tech was very through with the job of checking the system and advised me on the work done – I have always been very pleased with all the work done by the employees of Jos. Frederick & Sons in all areas for the years I have had them doing all the work in my home – I would recommend them for all areas. Kathleen F.”
“Amazing job by 2 curteous and knowledgable induviduals. Easy to talk to and explained the whole process, including how we were future proofing for a new lamp post.”
“Technician, Lucas Kemp arrived as scheduled. Performed 2024 annual inspection of residence AC unit including thermostat, and filter. Unit systems all in good working order . Reset thermostat for hot weather operation. Technician explained to owner what was done. Technician presented himself well, all questions were answered to my satisfaction.
All contact with Jos. Frederick & Sons front office were satisfactory as usual.
Thank you! Lee Alexander”
“Love this guy! He is a true professional”
“Lucas serviced our air conditioner and heater as well. He was on time, professional, friendly, and easy to communicate with. He was most efficient and replaced a dual capacitor on our air conditioner, which he had with him on his truck. After his explanation of membership, we agreed to join, which saved us money on service and parts. We hope to see him again when the time comes for future service. He is an outstanding employee.”
“So appreciate the plumber coming to same day of my call. Gabriel was wonderful – polite, friendly, professional and easy to talk with. He fixed our toilet and kitchen faucet expertly and made sure everything was cleaned well before he left. Am very happy!”
“Aaron was extremely professional. He explained everything while providing excellent service.”
“I could not be more impressed with the responsiveness and professionalism of these guys. My basement flooded and even though I wasn’t a current client, they dispatched someone quickly and installed a new heat pump quickly at a reasonable price. Highly recommend!”
“Lucas was courteous, professional, and explained everything in detail.
I would let him back into my house anytime.
Thank you”
“Fast an efficient service. Very helpful and explained how to use the new products and checked that it would not be a problen with our system. Very cooperative and a positive experience.”

“Gabe was very professional and did a great job installing my new toilet.”
“Gabriel clearly specified our options, worked hard to discharge the blockage in our kitchen sink pipe, and continued to check if he had succeeded. He spent hours working , decided he needed to use a wider snake, and worked until the blockage was cleaned. I appreciated his hard work, perseverance, and easy going communications style.”
“The office called to let me know Lucas was on his way. He arrived with a smile and promptly set to work. He took care to wear booties when in my home . He was patient with my questioning and the fee for service was exactly what he quoted when he looked at my air conditioning unit during a recent Spring Maintenance call .”
“Tim and Anthony did an excellent job this morning. My toilet no longer rocks from side to side nor does it leak around the bottom. They also replaced my flush handle and the inside workings. Not only that but everything was cleaned up perfectly. I expect my toilet to last me many more years! Thank you!!”

PS they changed their booties going in and out!”

“Service performed on 5/10/24. Main service was to install whole-house surge protector. Additional service was new ceiling fan transmitter and remote and replace sump pump battery. Arrived on time, explained the process, and we had final inspection. This duo is professional, respectful, patient – with a sense of humor.

“I’m very pleased with the service Dennis and Gabe provided. I appreciate how they kept me informed and explained what was causing the drain to continue to clog. I was given a price up front for the cost of the repair. They put down drop cloths to protect my floor and underneath the sink. The sink is draining better than ever now. I’m a very happy I called Jos. Fredrick and Son. The service was great, top notch. Thank you, Ron M.”
“Andrew and his partner were wonderful. Extremely . I had a very tricky light/switch issue. They consulted the operations manual, ON LINE (which I never would have thought to do) to fix it. Fabulous. Kudos to them both. Thanks. Paul J. Arendt”

“Tim and assistant ( sorry, I forgot his name) both very pleasant and courteous)..came on time to replace the sump pump , it was quite rusted (I assume from the age of the pump). They had the replacement on their truck, which is a time saver – the cost for the new pump, was a lot more expensive than anticipated – – therefore, for my reords, and IF I should sell my house.. I 'd like to have a copy of the SPEC's for the "new" pump, (I contacted (Sarah??) to send it via USPS or e-mail) Also,. I don't understand the "Warranty" coverage on this "New" pump, can I get a copy of that also?
Thank you. Lillian Collings.”

“Denis and Gabe were awesome. They were able to fix a hose bib for me without having to replace the whole thing which would have been a much more costly affair. I will continue to use this company and will highly recommend them to all my friends.”
“Lucas came out to check our gas heater for our maintenance agreement. He was personable and efficient. We have been customers of Jos. Frederick & Sons for many years and we have been very happy with their service.”
“I am a commercial Facility Manager with CBRE. Two ejection pumps/sewer pumps failed at a local urgent care center that I manage and because this was a medical center and they had already been closed for the day – it was an emergency. I attempted to use a CBRE approved vendor but he was unable to repair or replace the existing ejection pumps in my sewer pit. I began calling local plumbing/electrical contractors in the New Castle area. I had initially called Jos.Frederick and the woman I spoke with said there wasn't an available tech to do an emergency call. I got off the phone and started calling other local contractors. About 4 minutes later the same woman called me back and said that Tim R. had passed through her office while she was on the phone with me and overheard the emergency request. He said he'd stop by on this way home. Within 20 minutes he was on site at my urgent care center and identified the issue, but only after manually pumping out the pit several times. He stayed for 4 hours trying to work on this problem. He verified the equipment was in stock – and the next day showed up with the equipment and installed it and got us back up and the center opened. I would call this company again and again for help. They were amazing and reasonable and very easy to work with. I will definitely be calling them for all my plumbing and electrical needs in the future. Thank you again so much.”
“One of the best teams in Delaware . They did it all (electrical; heating; plumbing – full bathroom installation; sump pump; a/c ventilation). Outstanding service and sales.”
“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.”
“Great emergency service. I would call again for all my HVAC and plumbing needs. I highly recommended.”
“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!”
“He did an amazing job, installing a new gas line and my new gas stove”
“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.”
“Thank you, Donovan, for the excellent service. I appreciate your professionalism.”
“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.”
“Just wanted to write about the great service I received today. Dennis and Gabe were right on time, knowledgeable, did very clean work, and explained everything very thoroughly.
In this day and age of poor service these guys are top notch. I have found my new plumbers!!”
“Andrew and Cameron, were punctual, arriving in A.M. Very polite, explained how generator would be serviced. Obviously had material/supplies on their truck to complete the jobl.. Andrew explained what they did today, and it was time for the annual maintenence service. I appreciate their courtesy, professionalism, efficient service.
Thanks to Jos. Frederick & Sons for having both Techs. on your staff . . . fine reps. Lillian Collings”
