"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 Round Lake, IL

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
