Remodeling your home is a big venture, and it is important that you feel comfortable with the contractor you choose. With over twenty years of construction and remodeling experience, The RDB Remodeling Group takes great pride in our efforts on making our customers satisfaction the number one priority by exceeding their expectations. We build relationships with our customers because we have a client for life philosophy. The RDB Remodeling Group believes that it is our unique approach along with the creative suggestions from our staff that give us a distinct advantage towards making your wishes become reality.

"In Spring 2024, Bob responded to our request to add a roughly 240 square foot addition to the back of our house. From the first phone call to the final walk through, Bob was a trusted presence and thorough communicator. He listed to our requests, answered our questions, offered suggestions and explained challenges in a consistent, clear and timely manner (which was extremely appreciated for first-timers going through this process). It's been roughly 8 months since completion and having a new office and family room has made a HUGE difference in my family's quality of life. His costs were fair and, given that we made some slight tweaks to our original plans, we stayed roughly within budget in terms of time and money. I highly recommend Bob and his excellent team of subcontractors as well."

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