Welcome to Stress-Free and High-Quality Remodeling. A great remodeling experience doesn’t happen by accident—it starts with choosing the right company that offers excellence through expert project consultants, professional designers, dedicated project managers, master installers, on-time project completion, and a 3-year project warranty. Our smooth, simple, and innovative approach ensures that every step of your remodeling journey is enjoyable, fulfilling, and frustration-free. From design to management to installation—we do it right. No exceptions. If you're ready to successfully complete your kitchen, bathroom, basement, or home remodeling project, schedule your in-home consultation with one of our friendly team members at 847-809-3355.

"The quality of work is fantastic, and Marek is the best project manager you could ask for. The reason I removed one star is because I believe the quoted contract price, specifically for allowances, can improve. You should expect to add a minimum of $20,000 to your contract price. I also recommend referring to your contract throughout to ensure you aren’t getting an extra charge for something that should be included. Like I said, the quality of work is fantastic, but the up front pricing can improve."

High Quality Painting, LLC is a small company dedicated to offering services of remodeling kitchen, bathrooms and basements, paint, drywall,ceramic tile, we firmly believed that EVERYTHING IS FIXABLE. We are confident in the quality of our work, therefore offering warranty on every service provided to you, we guaranty the cleanliness on every step of our work from preparation of the work area to the final step, every day

"I contacted High Quality Painting LLC to repaint my fence after severely neglecting it for many years. Most of the paint was already stripped or peeling away, and had been for years, so there was significant damage to the wood as well. They were very confident about identifying the damaged boards and replacing them as well. When they got started, they found quite a few more damaged boards, and ultimately replaced more than what was quoted at no charge. They also recommended I get the fence stained instead of repainted, which is something I had not considered, and am very glad they pointed me in that direction because I think it will help prevent many of the problems I had in the future and be much easier to maintain. The workers were professional and willing to show up on incredibly hot days in between the rainy days to get the work done. I brought up another issue with the gate of the fence rubbing when opened, and that was also fixed at no charge which I appreciated."

"A.R.K. Specialty Service was a very professional family-run, business. From the start, they provided a very detailed quote for our custom-finished basement project and we valued their vast experience in recommendations of layout, design, and functionality of our space. The level of detail and input they sought from us was very much appreciated and we felt throughout the process their #1 goal was customer satisfaction and making sure we were extremely happy with the final result. The finished product blew us away. Our 1600 square feet of space was turned from a drab, cold, unfinished space into a beautiful custom bar, built-in cabinet large living room, 3/4 bathroom, bedroom, fitness room, and entertainment/game room.

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.
