"I wrote the C review. 3 years later, the windows leak every year and there is a leak in another room under the roofing that Sean "fixed." I have just learned that there are holes (where he put his scaffolding) above the leaking area. The windows were new and the only leaks are below the holes. I have spoken to other roofers who say it was a very poor job and should be redone."

FAQs for addition to existing structure building service projects in Plymouth, NH

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.
