"Mike and the people he works with are great. Very professional work. Provided most thorough proposal with pictures and explanation of costs, got started quickly, and worked around our schedule. Didn't skimp on quality materials. A few instances of not receiving information and project stalled a bit towards end. Some was supply chain, some was probably focus on other projects. Overall, very happy with basement remodel. Transformed and looks great!"

"I had the pleasure of working with Mike, a general contractor for my multi-unit investment property on the northwest side of Chicago. Mike demonstrated a strong vision for how to add value to the property, offering creative solutions (adding livable square footage to the attic unit for a duplex up) that made a significant impact. His attention to detail and ability to identify areas for improvement helped enhance the property's after rehab value, all while staying within budget. What stood out most was his excellent communication throughout the entire process—he was always available to address questions or concerns and kept me updated on progress (daily updates). His professionalism and efficiency were unmatched, making the project run smoothly from start to finish. I highly recommend him to anyone looking for a reliable, skilled, and thoughtful contractor."

"Ron and his crew took twice as long as quoted on my project which was a simple shower installation. When they said they were done, I found multiple mistakes. They used wood screws to secure a shower door frame and failed to caulk any of the joints. They also left a ton of damage to my walls that I had to call them back to repair and repaint. To aid with entry to my building, I loaned them a set of spare keys, which they forgot to bring and had to return on a separate trip. After I submitted the final payment, I found that they neglected to secure the button sill of the shower door at all and it simply slid out of place. I sent Ron a message asking for a return of my payment and he has been silent. Amateur work, no attention to detail, carelessness. Don't hire these guys for your project, hire professionals"

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