"RNR was hired to take on an extensive project that involved remodeling three apartment units in two separate residential homes. They were quick to respond to provide a free quote, honest about their capabilities for the services needed, and provided a fair price in a timely manner. On top of being incredibly personable and easy to work with, they take pride in their work, always keep a clean workspace, and absolutely deliver on whatever is asked of them (which in this case the list kept growing). They completely transformed the three apartments that they remodeled - from installing cabinets, countertops, toilets, showers, doors, light fixtures, flooring, windows, interior/exterior painting - to fixing unstable decks and chimneys, they can do it all! You definitely won't regret giving them a call!"

"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."

"Angel was the 1st one to contact us 8:00a.m in the morning when I checked out Angie's List. He came out to our home at 10:00 a.m. He checked out the mature tree we wanted trimmed. He gave us an estimate. We hired him on the spot. He was very business like. He was very polite. And he was very meticulous with his work. He deserves a 5 star rating! We'd hire him again or highly recommend him to family and friends."

"Work is basically ok but terrible communication and rather messy, including coming home to find the work crew having taken over my garage as work space without letting me know and leaving a mess for me to clean up. Owner didn’t seem to care and was not communicative of additional costs incurred. I would not recommend."

"The insurance company hired another remediation company on our behalf, but I contacted Rich for another estimate/opinion. Rich provided me advice via phone on multiple occasions, told me what to look for and assured me that the other company was following industry standards. Ultimately Rich came to our house to potentially provide us with an estimate on the rebuild portion of the remediation. Although we could not use Custom Craft Environmental for this project, I would recommend them to anyone and would definitely use them in the future, based on Rich's knowledge, responsiveness and professionalism."

"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."

"Elliot was great! He responded promptly to my initial request and came to my house shortly after to assess the project. That same evening he emailed me a very reasonable estimate. A few days later the project was complete. Communication was solid throughout the process, and I am very pleased with the quality of the build. We will cheerfully hire his services again in the very near future."

FAQs for addition to existing structure building service projects in Watertown, 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.
