"I bought a 105 year old home that has been in my family several generations. I knew I would need a lot of help to update yet preserve this California bungalow. Salvator immediately saw my vision, the houses potential and correct tasks needed to preserve, update, and reliably work on this unique home with the things I needed done. There were almost daily pivots needed and his crew (Emilio, Noe, Henry) rose to each challenge with a way not only to just make it work but also to improve what was already there. Salvator helped me make a few choices with his experience and expertise which worked out amazing. Salvator was the only contractor who recommended things to be done the right way not the cheapest way which would only lead to major and costly problems later. This is my second time working with this group and I would reach out again in an instant if needed. Their craftsmanship and professionalism is worth every penny and that is not always easy to find."

"I had a great experience with the DeBartolo family. Terry understands that customers are concerned with budget but also want quality work. That being said, we spent a hefty amount...but a lot of work needed to be done. I didn’t shop around much because once I met Terry I was sold. We communicated back and forth for a while until we came up with a new design and game plan for the kitchen. Terry provides a list of trusted vendors, which we mostly stuck to. They work Monday-Friday 7am-3pm, are polite and professional, do quick and quality work, and clean up every day before they leave. Once they started to work on the house they found many structural problems (apparently our house was thrown together quickly in the 80s). They did their best to do corrective work that fit into our budget. They gutted the kitchen to the studs, updated and improved the electrical, and installed the flooring and cabinets. They repaired many things in the house that needed attention. We now have beautiful cabinets and granite countertops as well as uniform flooring throughout the main level. They are very experienced and deal with permits, Village codes, and inspections so you don’t have to. They get great contractor discounts as well. I would recommend them to anyone who needs work done. My new kitchen is perfect."

"My wife and I decided to replace our dilapidated one-car garage with a modern two-car garage. We chose to work with Coach House Garages and could not be happier with our garage and our customer service experience! Having never been involved in a construction project before, the idea of building a new garage was intimidating. We found Coach House Garages here on Angie’s List and contacted them to get a little information. We soon met with Jeff Grummer and after that meeting, we knew we found our builder. We could not have asked for a better partner to work with than Jeff. He was extremely knowledgable, accessible, never pushy and was quite patient (as we had a lot of questions and no understanding of process or timelines). Jeff guided us through the inevitable ebbs and flows, from variances and permits to tear down and construction. When we hit a couple challenges, Jeff helped us navigate the issues and keep the job on track. We were...and are...impressed with the quality of our new garage and the professionalism of Jeff and the entire Coach House Garage team. We would highly recommend them to anyone considering building a new garage."

"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."

"We received multiple estimates, and decided to go with DesignFirst Builders for numerous reasons. Promptness, Showroom, the amount of different types of cabinets, counters, tiles, flooring and more. They also had numerous prices and quality from low to high depending on the cost of the addition to which build. From the start to finish of the project we dealt with multiple architects, designer's and project managers. Anytime we called or left a voice message we were contacted within the hour. Lastly I want to give a shout out to our project manager, ( Rick Divito ). Rick went above and beyond from the begining to the finish of our addition to make sure everything was perfect. If you want your project to be perfect I highly recommend using Designfirst Builders. They are the best !"

"I couldn?t be more pleased with the work Ellis from Erols Construction did at my home. From the start, it was clear he?s an expert in his field. His attention to detail is extraordinary, and every aspect of the project was handled with precision and care. He made sure everything, from the smallest joint to the final finish, was executed perfectly. What truly sets Ellis apart is his dedication to excellence and problem-solving. He went above and beyond, addressing challenges with skill and ensuring everything was completed to the highest standards. His expertise and experience were evident in every step of the process, and the results speak for themselves. On top of his technical skill, Ellis was an absolute pleasure to work with. He communicated clearly, kept me updated at every stage, and always made sure I was satisfied with the progress before moving forward. It was a stress free experience and I?d happily recommend Erols Construction!"

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