"Quality and craftsmanship was excellent. I trusted Chester, the project manager completely. Our house was over 90 years old and he went literally "above and beyond" to help us when unrelated issues happened to come up with our boiler. He employs very talented subcontractors that he has worked with for years and who helped contribute to the smooth completion of our project. He has excellent taste and was extremely helpful in offering his opinion when we decided to make some changes. We were very happy with the look and finish of our garage- we re-used brick from the demolition and he was able to make the exterior match our existing house perfectly. He is attentive and available to answer questions and personally inspected all of the work as it was completed"

"Very professional. Although bathroom was semi refinished, due to all the problems we had had with the company who had done the basement, we decided not to let the remodelers install the toilet and pedestal sink. Good call as it turned out to be more complex and I shudder to think what the original remodelers would have hacked in order to do it. The sink drain pipe had been torn off during demo and one of the two the two bolts on the floor for securing the toilet had also been sheared off. Paul told me that it would take more time then the big deal we purchased and also let me know about the extra charges for materials due to the situation. He was able to get the pedestal sink with faucet properly installed on the first visit. Then he called to let me know he had purchased the parts for the toilet install a few days later, came to our house at the appointed time and finished the toilet install. He invoiced me promptly via email and I was able to pay the extras via credit card. Both fixtures work well. Although it ended up costing about twice what we paid for the big deal, in the end we got a quality job from a very professional and knowledgeable plumber.

"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."

"I’ve always wanted a second bathroom. I contacted JK Complete R&C. Jack came to my home and assessed the would be project. Jack gave me a reasonable price, start and proposed finish date. Then I met the crew John, Mike and Ziggy. We had a great relationship. Everything that was to be accomplished was explained to me on a daily bases. By the end of the project we had a bond and it felt like family. I also learned quite a bit in the process. I am total fascinated with my new bathroom. I have already recommended JK Complete to family members."

"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."

"They were responsive, got the job done quickly and it looks great. We had two pillars removed and replaced. concrete was laid to keep them level and they painted all of the wood on the front of our house from black to white. Everyone was friendly to work with. I would definitely use them again for future house projects."

"­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."

"RC Brothers Construction remodeled entirely our kitchen and powder room, as well as installed new flooring in 5 rooms and completed a wide variety of smaller projects. They were responsive, responsible, and highly skilled in their work. Throughout the lengthy project, which was completed on time, Claudiu, Ruben, and Steffy provided us with invaluable advice and direction in addition to their exceptional work. All of them were always affable and attentive to our concerns. RC Brothers Construction has my very strongest and most enthusiastic recommendation. They are highly skilled and versatile, great people, and value the satisfaction of their customers."

"We worked with Linda at DESIGNfirst to scope out initial designs for multiple variations of a major multi-floor / multi-room remodel of our home. She was extremely helpful in proposing and developing design ideas and effective at working with her team to turn around our proposal variations in a timely fashion with high quality. We ultimately held off on our remodeling plans for reasons completely unrelated to the outstanding work Linda and DESIGNfirst provided. We hope to revisit our remodeling plans at the right time, and when we do, we know who we'll call!"

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