"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."

Whether the job is a small specialized residential renovation or a major commercial construction project, it will receive the same attention to detail and budget. As fully-licensed and insured on-site general contractor, we manage a team of skilled, professional subcontractors who understand our commitment to the highest quality craftsmanship.

Let us meet with you to show some examples of our diverse portfolio and talk about how we can help you realize your construction goals.

"We found Stan on Angiâ s List for a remodel of our unfinished basement and we were impressed with his knowledge, his ideas, and his commitment to doing quality work. When we first met, we told him that we had a baby on the way and were working with a tight window to hopefully complete the project before the baby was born. We hired him and we knew that we made the correct decision because he was determined to make that deadline (and he did). Stan also worked with us on our budget and helped us cut where we needed to in order to make our dream basement come true. He handled all of the permits and talked with the borough for us so we didnâ t have to deal with that headache which made the process so much quicker and easier. That was very important to us. Lastly, even though our project was smaller in comparison to what he normally does, we didnâ t feel like he cared about our project any less than others. The commitment and care did not go unnoticed. Thank you Stan for making our basement beautiful for our new family. Highly recommend!"

"Hired this company when my old deck started to fail. They are really transparent and communicate well. Provided me with a good breakdown of costs and a clear timeline. The deck is done and it is lovely. They suggested good improvements to the look and it made it much better than the old deck. Love it. Cost was comparable to what we were quoted by other contractors, but they used a higher grade trex material. Overall very satisfied. Will work with them again if I need future work on the house."

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.
