"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!"

"Shire Group did an amazing job with the exterior and interior work done to an add-on room on my property. Ben and Isaac were great to work with on everything from communications, expectations and updates throughout the job. I'd highly recommend working with Shire Group!"

"Exceeded all expectations. Reached out to 7 Madison area interior contractors at the top of Yelp / Google in late July to get a quote for closet removal along with the possible addition of flooring work. Of the 7 contractors, 5 responded and came out to survey the job. Only 2 got back with rough quotes, a 3rd wanted ~$1k to come up with a quote. VM Contracting's quote and start date matched my rough budget and timeline expectations for the job, whereas some other quotes exceeded VM's by nearly 8x and could not begin work until 2-3 months later. Went ahead with VM and was not disappointed. They started work within ~2 weeks and I was so pleased with the closet work, that we expanded the scope to vinyl flooring & trim across the entire 1st floor. Again, the cost and timeliness were excellent. Would go to VM for any future work without hesitation."

"Not once during our entire basement finishing process did I question our decision to work with Mike Hessling at Catalyst (formerly Apex). The entire process took just over a month to go from a completely unfinished basement to a brand new, beautiful, rec room, office, and 3/4 bathroom. Mike even dealt with all the curve balls we threw him along the way, switching colors midway through painting, adding an additional cabinet here. He is the kind of contractor you dream of. He's hands-on, there first thing every morning doing so much of the work himself! And the coordination with all the subcontractors was amazing. Everyone knew when and where to be and what exactly needed to get done. To top it all off, he came in right on budget as quoted (which was very fair). Mike's brother Adam was also key in the build, working hard with Mike or on his own."

"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."

"I needed to put in a concrete barrier. Andrej came by and gave a very low estimate. I was initially concerned about the low bid. I was also concerned about the low scores from other reviewers on Angie's list. I noticed however that many of the reviewers had not actually used Andrej's services and were simply concerned by his low bid or maybe his accent. Who knows. 
Needless to say, I had Andrej complete the work. He did a great job on the concrete. He came back after a couple of days to repair spots in the concrete that I did not notice and did not care if the spots were repaired. Andrej insisted on making the repairs. 
I have used Andrej on second job already. He did a great job on the second concrete project too.

FAQs for addition to existing structure building service projects in Sun Prairie, WI

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
