Q: Are hidden rooms legal?

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.

Q: What should be in a safe room?

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.

Q: Does a secret room add value to your home?

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.

"We had Eric add an addition to our garage and extend the roof over the front porch. We also had the front porch replaced and had new shingles on the whole house. It was a fairly simple job complicated by lots of rain. We were kept informed of any delays and when contractors would be working. The job came out looking great. The best compliment you can say about an addition is that it looks like it was always that way and it certainly does in this case. I highly recommend Somrok Inc."

"We added a full bathroom in our garage and an additional 16 ft wall with an interior door. The project went well and we’re very happy with the work that was completed.

"I have used other contractors in the past this was my worst experience. I called to schedule an estimate and they were booked out 6 to 8 weeks as of March 10 I got an estimate date first week of June the Day of the estimate I received a call if they can reschedule next week they were busy which I agreed upon. The following week they came out took detailed information on what I needed done and stated they had to draw up an estimate and will get back to me. After the third week I started calling to see where the estimate was it took them three more weeks a total of six weeks to get me an estimate and then the estimate wasn’t of the whole project I wanted done. They missed several things so then I got the second estimate which I agreed upon and they stated they will call back with a date for repairs. Second mistake I waited another four weeks before they got back to me with a date on Monday and Tuesday the end of September. They arrived on Monday and Started some of the work I was a little concerned and called Dean Martin co owner and discussed my concerns the following day they did some adjustments and by the time I got there after a four hour meeting in the morning they were gone. Two workers no more than nine hours of work and they stated they will get back to me with someone to do the drywall patching. Granted this was Tuesday no one got in touch with me until the following Wednesday when they asked if they could come in that Thursday which I was out of town. This is incredibly frustrating they are not well-managed in the Their projects. Granted the flooring was nice but the patch work was disappointing for that price entire walls should be replaced not small sections. So now I had to go ahead and hire another contractor to finish the work and the New contractor got back to me the next day. Angie recommended Action Door they were expensive however I thought that came with their work ethics and quality of work which I am far from impressed. I would not recommend this company to anyone. I just lost $4000 down payment incredible"
