"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."

We invite you to be a part of the Platinum story, where your project is more than just another job—it’s a personal investment in quality, care, and craftsmanship.

"I hired Platinum Touch Industries LLC in the summer of 2018 for my first Fix and Flip remodel project and was impressed with their work. Vince and his team did a fantastic job from demo to cleanup to the finish touches per schedule. Vince was honest at front and very professional. Based on the Scope of Work I presented to him, we were all in the same page. Once milestones were completed within the Project Timeline, payment was made to him in a timely manner. Platinum is honest, reliable, and work ethic is impeccable. I was impressed with their work and demeanor, I hired them again the winter of 2018 for a minor remodel on one of my rental properties and in the Spring/Summer of 2019 for a Major Rehab on a Fix and Flip project in the Lombard area. I would recommend Platinum Touch Industries in all aspects for your Construction Project, whether it is a minor remodel to a major rehab. Thanks Vince and Bob for all you do. Keep up the Great Work!!!"

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