"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!!!"
