"Perfect. Did a very nice job and wouldn't hesitate to hire Phil again."

"I hired JDC Contracting for a full kitchen remodel, along with small updates throughout my house (new lighting, replacement of interior doors, a new ceiling in the basement, bathroom updates, and numerous other things). John did nearly all of the work himself. He did a wonderful job and our house looks fabulous! I can't say enough about JDC. John is skillful, completely accountable, and fair and honest in pricing. Hiring JDC is a a collaborative project from start to finish. He took the time to hear our ideas, provide sound, practical input, and put together a good, workable plan. After discussing things (every step along the way), John turned what we wanted into reality. He's also kind and a pleasure to work with. I really enjoy interacting with him. I had received estimates from two other kitchen contractors. John was the third contractor that provided one. He really impressed me with his attention to detail, his knowledge, his demeanor, and his being up front about process, pricing, and so on. He left a great impression, so I hired him in late November. John transformed the small, enclosed kitchen into an open concept kitchen that's bright, spacious, and inviting. This was the first time that my wife and I were involved in a major remodel. In December, we were so happy with how the kitchen project was going that we asked John to do additional work on the house. We wanted to squeeze in some more work at our house before he got too busy with other customers' projects. The additional work included the door replacements, as well as partial updates of the bathrooms and basement. He is an HVAC expert, so he also gave great advice on how to maintain and extend the life of our older HVAC system and other mechanicals. His advice is saving us a lot of money. John does such terrific, fairly priced work, we would totally have gone with JDC for full updates of the bathrooms and basement, but we didn't have the finances. So we decided to go forward with partial updates that really changed the 2 bathrooms and basement, while allowing us to stay within our budget. We're grateful to John for these secondary projects--and his ideas for them--because they have given us a lot more living space, and have made the bathrooms much more pleasant to use. We recently purchased the home in Oct. 2022 and we initially had a 3-5 year timeline for improving the kitchen, bathrooms, and basements. But John shortened this timeline down to a 2-month time frame (around 35 days of actual work--there were a couple of delays on materials that slowed us down). We moved in a week ago and are loving it! In sum, I strongly recommend JDC for home improvement projects. John is highly skilled and has integrity and tons of expertise and experience. Most important, he genuinely enjoys making his customers happy by improving their homes. He went the extra mile for us and has definitely made my family and me happy!"

"It went outstanding! They weren't any inconveiniece, great communication, had everything ready to go."

"Very easy to work with, did an excellent job, and stayed within budget. This was a custom, unusual garage."

"contacted T&K Builders after discovering mold in my exterior wall, and their response was immediate and professional. The team quickly demolished the affected area and installed the necessary structural supports to safely hold the roof. Everyone on site worked efficiently, communicated clearly, and maintained a high level of professionalism throughout the process. They kept the site clean, protected materials from the elements, and were extremely organized—especially important since we received over four inches of snow the following day. From start to finish, the experience was seamless and stress-free. Their attention to detail, workmanship, and respect for the property truly set them apart. I would absolutely recommend T&K Builders for any future projects and would not hesitate to call them again."

"Alberto and Elizabeth helped us through a complicated remodeling of two bathrooms with title suggestions, a quality vanity and quartz vanity top as well as trying to schedule the work to be completed in a timely fashion. While it took longer than expected, each crew of workers tried their best to make the job right including some things that had to be redone. The final results, which included removing one wall and rebuilding a shower stall in one bathroom, are dramatic and beautiful. I would recommend this company."

"Great! Super professional and easy to work with. Their team is timely and well coordinated. Super experience!"

"Bob is extremely knowledgeable about his products and services and understands the customer. He is very responsive and prompt, and while he explains everything in detail he also listens carefully. He is realistic and not high pressure. Thank you Bob!"

"They did everything we wanted quickly and at a good price. They were easy to communicate with and quick to respond."

"In 2017, when I was looking to purchase a house in the Rockford area that was needing a full siding install I contacted GF Company in Belvidere. IL, who I found on Angie’s list and at that time GF Co had great reviews. Strangely enough these great reviews are no longer to be found on Angie’s List. It should also be noted there is a GF Siding in Cherry Valley. IL, this is Not the company that I did business with. Ariel Zmijewski (the owner) got me a quote quickly and I decided to purchase the house. A few months later in July 2017, I contacted Ariel again to discuss the finer points of the quote, the price was revised slightly and the Ariel mentioned that once a deposit was paid work could start 6-8 weeks later, but said the install would be finished before the cold weather arrived. I started creating a color layout and Ariel provided some feedback on what would work and not work. To this point I was very happy with progress. In September 2017 I paid a deposit of over $8k (about 44% of final price) and awaited updates for a start date. Nothing happened. In early March 2018 I contacted GF Co by phone stating that I had been very patient and they had had $8k as a deposit for the last 6 months and I had nothing to show for it. After a couple more calls and emails Ariel showed up with his foreman Mark and they said that work would start in the middle of the following week. Much to my surprise the work started on time. Over the course of the next 4 weeks Mark and his crew worked hard, only missing a few days due to bad weather, I even agreed to having some extra work done by the team, some wooden entrance steps that needed replacing for an additional $2.5k. By early May 2018 the job was finished the house looked great and I was very happy with the work and appearance and was getting compliments from neighbors too. The balance of owed of over $10k was paid with 48 hours of the work being finished. Again I was happy with work done, until… A few months after the install a TV cable box started having troubles. Cut a long story short the wall socket died because cable was suddenly defective, also the crew had moved the exterior cable input box and this didn’t help the issue. Comcast fixed it, but I now have an exterior cable showing and they had to drill through the siding. Then around Halloween 2018, less than six months after having the install completed, I noticed that a piece of siding (6ft approx.) had become detached underneath a window, trying to pop it back into place did not resolve the issue. After checking all the other exterior windows I noticed 1 other window was about to do the same thing. I called the GF Company main number and left a message with the receptionist for Ariel to contact me. No response. I called again a couple of times and left more messages still no response. In March 2019 siding problem under windows still Not fixed, I called GF Company again, no answer, and no voice mail. I called a couple more times on different days still no answer or voice mail. I then sent an email to the company and to my surprise I received a response from Ariel stating this was the first that he had heard of it. About a week later (3/26/19) he showed up at my house to view the problem. Ariel stated that he would get someone over to fix the problem, but would not give me a date or time. On 4/2/19 I emailed Ariel again asking for confirmation of a repair date ? Nothing but crickets… On 4/30/19, I sent another email to Ariel requesting that the repairs be completed before the end of May 2019, again no response. Quote / contract says: Customers will receive a Lifetime Warranty on Material and Workmanship Reported GF Company to Illinois BBB on 6/5/19."
