"Bob and his crew are the best. This was a major renovation and complete re-do of a split level house that we converted to a more traditional house. 95% of our house was redone. Bob is meticulous and his subcontractors are fantastic at their crafts and very loyal to Bob for good reason. He was pretty instantaneous in his communication with me even on weekends, which we rarely bothered him in. This was a mid 6 figure job that Bob said would take 4 1/2 to 6 months. They finished in 5 1/2 months which is pretty amazing during a pandemic with major supply chain issues. Bobs bid wasnâ t the lowest, but it wasnâ t the highest of the 5 bids we received. They were pretty much on budget except for material price increases, especially lumber which was not his or the lumber yards fault. If youâ re thinking of hiring MZ Development you will not go wrong if you hire them to do whatever size project you are thinking about."

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."

"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!!!"

"We now have a beautiful kitchen. This price tag was on the high end, but that may have been due to either the high price of lumber at the time (Canadian wildfires) or the customer cabinetry that we needed or both. There were a few instances where I was glad we were on sight as I don’t know if the errors we saw would have been caught prior to them being installed. The upfront design and visualization is top notch, as is the quality of the material. The labor used to install was three star at best."

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