"We just had our roof replaced by Cody and his team. Everything from start to finish was done professionally and skillfully. The roof looks great. His team came in, stripped the old roof off, got the job done quickly and cleaned up every single thing that fell in my yard. Amazing crew. Fantastic job."

Tim and his team are wonderful to work with, he listened to our ideas and helped us make them come to! We are so happy with the finished product and working with Tim that we are going to use him and his team on our next project!"

"Jim and crew are reliable and knowledgeable. I agree with all that Dana C in Kensington shared. We hired Jim to close in a carport for an addition by seeing the work he was completing for Dana. I then had him remodel an old garage that needed a face lift. We now have Jim building a ranch home for us from the ground up. It is going just as well. If only the prices due to the economy were not so disappointing. Materials are through the roof as a result. Here hoping for some REAL change in 2025 !!!!"

Meeting somebody, being invited into their house, and listening to their ideas of how they would like to transform their space to better suit their needs excites me. It brings me immense pleasure to be welcomed on an idea based visual journey in creating a customized dwelling in order to improve the quality of function in somebody's daily home life. Bringing ideas to fruition is my specialty. With equal enjoyment in making those popcorn ceilings that you've adored for so long disappear in an array of smoothness, gutting the kitchen where nothing seems to fit anywhere, including the cook, and installing cabinets and lights that transform the "heart of the home" into a space you don't want to step out of, or erecting that garage and mudroom to get your cars out of the weather and the clutter out of your foyer. At Magic Frog Carpentry & Woodworks I live in a solutions based mentality.

"Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

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