"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."

Customers say: Super punctual

"I cannot say enough good things about this company and the owner, Angelo. He designed and built a new dining room addition and remodeled my existing deck. He communicated with me every step of the way and responded immediately to any and all of my inquiries. Two years after the project was completed, I had a small issue. I called Angelo and immediately he scheduled a team to come and repair it for me. The quality the work is beyond reproach. I would recommend Angelo and AP contractors without hesitation."

"We had a great experience! Javier was onsite and hands-on with the project. He was also extremely responsive. He ensured everything was well coordinated and had his crew working around the clock to minimize the amount of time we had to be closed. I have had work done in my home that took months and this was an extensive remodel done in a couple days - amazing!! The workmanship was also top quality and Javier made sure we were satisfied with everything that was done. I would highly recommend!"

"I would give zero stars but it makes you at least give one star. Do not use them they will take forever to finish the job. I believe they are running a Ponzi scheme of a company, or at least that is what it appears to be with the amount of work they are getting done around here. It seems like they used our money to get their bigger clients' jobs done and not our job. The amount of work they have finish in the past five months could have been done in 4 or 5 weeks. There have not shown up to work for multiple weeks, and when the do show up it is one or two days and they only get one thing done. Don't fall for the "you need to pay us money at different phases" and then they don't show up. They claim this doesn't usually happen but they are NOT doing anything to get things done any faster. They continue to tell us someone is coming to do such and such work and NOBODY shows up. "

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