"We used level 4 customs to remodel our upstairs bathroom and they leveled our home to the tune of over 10k in water damage to our home not to mention the mold issue we now have to deal with in our home. Troy had 2 guys do the entire job not once checking on the work being done. We had a bathtub installed and the workers somehow installed the tub without cutting into any wall to hook up the drain. The first time we used the tub it leaked to our downstairs and we called Troy who told us it was not the tub. When he finally came out to look at the job it was determine his workers never hooked up the drain correctly when I poured water down the drain and it went all over Troy who was on a ladder in my ceiling . Two years later we have a leak again, this time much worse. The workers installed the faucet incorrectly (confirmed by 2 plumbers) and Troy says it is a faulty faucet (does this guy take any responsibility for the work his guys do). Not too mention when they did the work his driver ran over our backflow with a trailer shooting water everywhere(which my neighbor saw happen) that both the driver and Troy denied. Also the grout in tub started falling apart 3 months after the job was done. We are having to spend more money to fix the incompetent remodel that was done than it cost to do the remodel itself. After running over our backflow, not hooking up the drain causing a leak and not hooking up the faucet correctly you would think they would help resolve the issue. However , they are refusing to accept any responsibility and at this point its not even surprising. I have a 12 year old child who takes responsibility for his actions better than the adults that run this horrible business. I wish I would have never had this company do any work on my home. We are still getting mold testing and mold mitigation issues resolved and who know the cost or even worse the health issues this has caused my family."

"I am a real estate broker and had a client hire Core Development Group, LLC to complete a project that required rezoning and new construction for a residential house. The process went smoothly and the final product showcased quality work. It is hard to find a contractor that can take a project such as this, and manage a smooth and timely process which is also quality work."

FAQs for addition to existing structure building service projects in Longboat Key, FL

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.
