We are known to pay exquisite attention to detail, while making customer satisfaction our top priority. Call us today to learn more about how we can help you!

"A.R.K. Specialty Service was a very professional family-run, business. From the start, they provided a very detailed quote for our custom-finished basement project and we valued their vast experience in recommendations of layout, design, and functionality of our space. The level of detail and input they sought from us was very much appreciated and we felt throughout the process their #1 goal was customer satisfaction and making sure we were extremely happy with the final result. The finished product blew us away. Our 1600 square feet of space was turned from a drab, cold, unfinished space into a beautiful custom bar, built-in cabinet large living room, 3/4 bathroom, bedroom, fitness room, and entertainment/game room. Our family will enjoy many years to come in this beautiful space A.R.K. Specialty Service created for us and we are extremely happy we chose them to build us the basement of our dreams!"

"I would give zero stars but it makes you at least give one star. Do not use them they will take forever to finish the job. I believe they are running a Ponzi scheme of a company, or at least that is what it appears to be with the amount of work they are getting done around here. It seems like they used our money to get their bigger clients' jobs done and not our job. The amount of work they have finish in the past five months could have been done in 4 or 5 weeks. There have not shown up to work for multiple weeks, and when the do show up it is one or two days and they only get one thing done. Don't fall for the "you need to pay us money at different phases" and then they don't show up. They claim this doesn't usually happen but they are NOT doing anything to get things done any faster. They continue to tell us someone is coming to do such and such work and NOBODY shows up. "

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