"We hired this builder for an addition to our home and had a great experience from start to finish. The team was professional, responsive, and kept us informed throughout the entire project. They paid close attention to the details and made sure the new space blended beautifully with our existing home. The quality of the work exceeded our expectations, and we couldn’t be happier with the finished addition. I would highly recommend them to anyone considering a home addition or renovation."

Customers say: Super punctual

"Angelo did everything as planned. We walked over the construction plans before construction started. Site drawing detailed how the finished room addition and sun porch would look after the job was completed. Wife and I were completely satisfied with the finished job. Ready for summer 2021 with or without COVID... Construction crew (Framers) did a fantastic job. Always arrived on time and job was completed on time. Will be happy to recommend AP Builders for any residential construction project."

"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!"

"They built a full porch after they took down my existing small stoop porch. It looks better than I could have ever imagined. They explained everything as they went was a great experience."

"Brandon is the first contractor we have hired who showed up (early) was meticoulas with his craftsmanship AND did a beautiful job.

I love my deck and will use Stoffel for all my carpentry and building needs."

"They were fabulous - can't say enough about the team. On-time & on-budget (always a win), but respectful of our home and family. Not only were they were professional, knowledgeable and experienced, they were true craftsman - a rare find these days. Roman and Harry even took time to teach me a few things for future DIY projects. I would 100% recommend them!"

"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."

"I am very pleased with the renovation results that Cardona services gave me. My 1972 Manufactured home needed an update and reinsulation. My house was drab and chilly in the winter. Ricardo had good ideas and satisfied any concerns I had and it showed. It was recommended to insulate the ceiling first to prevent heat from escaping as it rises. Ricardo recommended R5 insulation board to be covered by a smooth covering. I was concerned it would bring my 7ft ceiling down and feel claustrophobic. But, gaining heat efficiency was the priority so, I agreed to Ricardo's plan. To my surprise, when Ricardo was done, my ceiling seems even higher! The rooms feel more spacious. I love it. The new hallway doors with black knobs are stunning, along with the new black bathroom faucet. My Manufactured home feels like a regular home . We love our new surroundings. Thanks Ricardo and Raymond from Cardona! I highly recommend them."

FAQs for addition to existing structure building service projects in Lake In The Hills, 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.
