"My husband and I used HomeAdvisor to assist us in finding a contractor to remodel our guest and master bathroom. We were incredibly lucky that Ultra Source Performance was first on the list! Frank worked with us from beginning to end, was incredibly professional and easy to communicate with. In the very beginning of our remodeling plans, he took time out of his already busy schedule to talk us through our ideas and give us his two cents. Jason and Dakota, who did the majority of the handiwork, kept their work space very clean and tidy. They were very friendly, easy to work with, and respectful of my home and belongings. I definitely would not mind them coming back to do more work on my house! The end product of both bathrooms was phenomenal, especially my master bathroom. I've gotten comments that it looks and feels like a high-end hotel bathroom, which I think is one of the highest forms of praise! Even after our bathrooms were finished, Frank has made it clear that if there are any issues that come up, we could reach out to him. We've had a couple tweaks that needed to be addressed a few months after their work was done, and Frank was always quick to respond. I never expect him to respond right away, but he makes it clear that he cares about his craft and his customers. Thank you, Frank, Jason, and Dakota, for transforming our bathrooms!"

"I can't say enough about A P Builders and how absolutely wonderful they have been from start to finish. We completely gutted and remodeled our home and Angelo was upfront, honest, timely, and everything that was contracted was done to perfection. We had crew there every day from start to finish. He started on time and finished on time. Any change orders were handled professionally and solutions were found for any unforeseen challenges due to the age of my home. I highly recommend AP Builders for any of your home improvement needs."

"We met with Charlie Murphy several times to discuss the possibility of using Icon Building Group to build our house. Charlie was concerned that they would not live up to our high expectations. In the end, they not only met our expectations, they exceeded them. Icon assembled a talented team to execute the building of our house. They selected a group of subcontractors that had the necessary talents and attention to detail to be able to execute the detailed design that we entrusted to them. The efforts of the subcontractors were carefully guided by our superintendent, Mike P. In the office, Shawna H. did a great job navigating our project thru the challenging City review process. We had several challenges during the project, and the Icon team dealt with them in a positive manner. We are extremely happy with the end result and look forward to enjoying our new home for many years to come! Bob and Pat"

"­We are very happy with the new custom home Clean Edge built for us. True to their name, they provide a great attention to detail. The quality of the construction is very high, with solid materials and also an aesthetic on the finishing touches. You have to look very hard to find any imperfections, and then they correct those quickly. The owner is very focused on this approach, providing products and services a cut above the rest. This company is a rare find and I would not hesitate to engage them again any time."

"Jim from Independent Remodeling is a great contractor who works with a great team and I highly recommend him to anyone. He helped us out when another contractor abandoned our complete Rehab job and gave us a great price and was SO patient with the whole project. We ran into problems and delays with both the bank and the city and Jim was great about it all. His team did an excellent job on our home and we are very happy with the time it took and the end result. He is reasonably priced and works with your budget as much as he can and he stands behind his work!We will definitely be calling him for future projects!"

"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."

FAQs for addition to existing structure building service projects in Algonquin, IL

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.
