"High Quality Painting does far more than painting and we hired them to renovate and expand our kitchen and relocate our bathroom. My wife and I are an interior designer and architect, respectively, and drew up the design ourselves, which included some high-end finishes. Salvador made several recommendations that we followed to improve the design. His team was polite and worked 8am-5pm, six days a week, until the work was complete. Any home renovation is going to be painful for the residents, but Salvador and his team reduced our discomfort and anxiety with good communications and effective dust control measures. His costs were fair and well-documented and he worked to make sure we were completely satisfied. He even had his team make improvements to our HVAC (that we had not asked for) to improve the air flow in the home. We had one call back for a correction, which Salvador promptly fixed. My wife and I highly recommend Salvador and his team and would definitely hire them again."

"Jack took detailed notes during home quote visit and provided us an initial estimate over the phone. His proposal was comparable to other bids we got. We decided to move forward and he sent us a written estimate via email. The first estimate was slightly over original amount due to known possibility with electrical and additional work we wanted. They started the project and it took about 6 weeks to complete. There were some bumps in the beginning with days/time they were working but we were able to sort that out and all was good. Ralph was the main guy that did most of the work. He did a nice job and made sure to clean up after the end of each day. Basement turned out great and We are very happy with it."

"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!"

"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."

"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."

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.
