"I found Armagh on Angi. I had a ceiling/attic trap door mishap on Friday 11/24. Called today, 11/27 at 9:30 am. Raymie agreed to come out and repair the spring @5:30 pm. Verbal agreement, on time and fixed the spring. Minimal charge. I will definitely be using Armagh Carpentry for future projects."

"Declan and his team installed tongue and groove wood on my covered porch. The team did an excellent job, with a focus on quality. The job took place over two days, and I was impressed both times with the crew. They started first thing in the morning, were respectful of my home, were very kind, and cleaned up SO well. They took care in picking the best pieces of wood during install, and asking if they had any concerns about a piece. They ensured two different sections of the ceiling were aligned, and it looked impeccable. I am very happy with my experience, and hope to use them in the future again!"

"Joe and his team did a fabulous job on my addition of 1,000 square feet, consisting of kitchen, living room, studies, closets, and a gas fireplace. It has soaring cathedral ceilings and strategically placed lighting. While I did make a few changes, his team offered suggestions on what would work the best from an aesthetic and construction point of view. And they were absolutely right. From start to finish, Joe kept me informed of the proposed time frame, the costs, and the delivery of materials from vendors. Whenever I had questions, he answered them, and believe me, he has the unique talent of making technical explanations into clear, comprehensible English that I was able to grasp. All the workers on the job were smart, hard-working, efficient, and best of all, tidy. Best of all, the budget that Joe had created was accurate; the only overages were items that I added after the fact. Don't hesitate to hire Joe and his team. They are honest, forthcoming, expert, and ethical!"

FAQs for addition to existing structure building service projects in Bryn Mawr, PA

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.
