"Chester and the crew at Above & Beyond Construction are great! They completed our home addition and we look forward to working with them again on any future construction or home projects. Project - home addition above existing garage (bedroom and full bath) Budget - the stated budget was the final cost. Any additional costs associated with the project were well communicated (before the work was done) so we were not shocked or surprised. Craftsmanship/Work - the crews arrived on time and ready to work. They showed great respect to our house and neighbors. If they saw something that they were concerned about, it was addressed and discussed. The go out of their way to do it right, the first time. Chester was also able to find subcontractors that performed quality work that were budget friendly and timely (for example, we didn't have to wait days/weeks for an electrician/plumber to show up). We felt like we were their top priority even though they had other projects they were working on. Permits - Chester and crew handled the permits and communicated the project with our architect. His crew would also meet with the City for the permit inspections, which were approved on the first inspection because he and his crew do things the right way. They were very knowledgeable about what the City wants/prefers so inspection/permit process was easy. Communication - Chester was our main contact but we also felt comfortable talking with any crew members about our concerns. Chester was always available and just a phone call away to help resolve any problem or also answer any questions we might have about the process and next steps as the addition was being completed. It was great working with Chester and his team at Above & Beyond Construction and we would recommend him and his team."

"I am 100% satisfied. From the very beginning, Howard demonstrated his committment to the project. It involved gutting two kitchens down to the studs, gutting bedrooms, installing new cabinets, installing kitchen fixtures (dishwasher, sink, garbage disposal), installing all new solid wood doors including locks, installing windows, insulation, a concrete sidewalk, a new exterior staircase, electrical work including recessed lighting and new outlets, refinishing the hardwood floors throughout. I’m probably leaving out some work but this is a list of the bulk of the work. My wife and I are 100% satisfied with the quality of Howard’s work. I am impressed with how clean and organized the work area was at the end of each workday. Howard’s team of workers were professional, courteous, and helpful in solving work related issues. Debris that was stored temporarily in our garage was also carefully organized and consolidated. When the debris was hauled away, the garage floor was swept and tidy. Howard is easy to talk to and he is flexible with changes that I made to the scope along the way. For example, after his workers began demo work I asked to reconfigure a closet opening. The next day his crew was making the change and it turned out better than I had planned. Howard completed the job on time and on budget. There was not even one small “extra” charge to the original contract. In fact, he did extra work that was not in the Scope. For example, a wood winder stair sustained damage at some point in time – before I bought the building. I lived with the damaged stair because I did not think it could be fixed without ripping up a large portion of the staircase. I didn’t even ask to have it repaired but Howard brought it to my attention and said that he would figure out a way to repair it. He made a small opening underneath the stair, in the room below the staircase to gain access. This attention to detail really set Howard apart. The stairway is now 100% back to its original condition when it was built, probably about 90 to 100 years ago. I started rehabbing small (1 to 4 unit) buildings in about 1985. I’ve used many contractors over the years so I can say with a reasonable level of real life experience, that Redstone is the best contractor that I’ve worked with. I recommend Howard without reservation and without any qualifiers."

"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.

"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."

"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."

"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."

"Tom Tishby who was the Project Manager and led the crew of the Chi Renovation and Design on our project involving complete remodel of our kitchen and the powder room have done an outstanding job. Our kitchen remodel project involved removal of the wall to open up the galley kitchen, this required rerouting of the water pipes and installing new plumbing and wiring system. The crew worked efficiently they were very professional and neat while we were living in the apartment during the construction. The products of their work were outstanding in quality and precision. They met all the deadlines and provided courteous service. Communication was excellent throughout the project. Another important factors is that the crew and Tom Tishby in particular worked really well with our building engineer and manager making sure all the paperwork was an order the use of the service elevator and disposal was done according to building policies. Overall I’m very pleased with Tom Tishby and Chi Renovation and Design and would to continue working with them again on our future remodeling projects."

"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 !"

FAQs for addition to existing structure building service projects in Harwood 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.
