"It was great to work with Icon Builders to building our dream home. They went out of their way to accommodate the completion of our home build in time for school. Their response times are great and the staff is truly personable. It was great working with Jenna, Natalia, Joe, Scott, Shawna and Charlie. I will recommend Icon to anyone looking to build a custom home."

"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."

"Paul gave us an estimate shortly after we requested one.  We had recently had asbestos vinyl tile and mastic removed from our basement, and in the process had to remove a built-in bench which left the lower
part of an otherwise paneled wall exposed.  Another wall had paneling that was mismatched from top to bottom.
Also we have a staircase with vinyl asbestos tile that we wanted to cover.   We wanted to install ceramic tile on the basement floor, but were unsure what to do to fix the walls and stairs.
Paul told us "everything is possible" when we asked him what we could do to repair the wall and cover the stairs.  Paul suggested that he would install oak treads and risers on our staircase up to the kitchen.   This was a unique and welcome
suggestion as we had heard many others but did not feel satisfied with any of them.  He told us he could fix the walls and do the tiling as well.   His estimate was timely and detailed.  We liked the price so we went with his team. 
They were punctual, professional, and made our basement walls and staircase beautiful!  He repaired both walls so that they both look better than they ever had.  The wall where the bench was removed ran short of panels, so Paul and his team took a small,under-the-staircase door made of the same material to finish the wall.  They replaced the door so that it works better than the old one and looks good.  The tile has brightened up the whole room and the baseboards and moulding have finished the look so we feel we have a new living space.  The staircase is beautiful!  We love our basement now!  Paul and his team went above our expectations, and we would hire them again for sure.

"John and 41 North is great to work with and very client-service oriented. His prices are fair, the estimates are detailed, his team's work is of high quality and he is very communicative. He did some remodeling work for us on our siding, deck and windows and we were very happy with the results. He also upgraded our electrical. We then re-engaged the next year to do our hardscape patio and back landscaping. When rain delayed our progress, he rushed the job to get it done in time for a party we were having. We intend to continue working with 41 North as we continue to upgrade our older Chicago home. I highly recommend this company."

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