"We hired Mangone Contracting to build a sunroom and deck on the back of our house. Working with Eric and his team was a real pleasure. We could not have asked for a more gracious and talented crew. Eric's team handled EVERYTHING... designs, permits, construction, finishing, and several final adjustments. We are delighted with the outcome. Even the building and electrical inspectors commented on the excellent quality of their work. I highly recommend Mangone Construction - without reservation. They will be my contractor of choice for all future projects. "

Miller Contracting, Inc., offers design services for all of your projects or we can work with your architect. We look forward to working with you, so please give us a call today!

"I had a great experience working with Tim to add a large sports room onto the back of my house in Etna. I had several conversations with him about what I was looking to do and then he put together a very reasonable project. I really like how Tim manages the money and the various contractors he works with. He put together a plan for me paying him based on the various milestones of the project, which then involved different people for the foundation, insulation, drywall, electrical and so on. This kept everyone on schedule and the entire addition was completed between April to early-July of 2023. I also had him put in hardwood floors throughout the entire first floor of my house. It is such a great improvement to the living space. Just excellent work and completeprofessionalism from Tim and his crew and the contractors he works with. True to form, Tim has stopped by since then to check-in on things and answer any questions I've had. I will definitely work with Tim again."

"Jim and Danielle help me take a room that was old-fashioned and in need of a remodel into a space that is very warm and inviting.

He gave me lots of ideas and choices from flooring to fixtures. As the crews that came into the house were friendly and considerate of my privacy as I work from home.

"This company was awesome to work with. All of the guys doing the work were super polite and respectful. All easy going and willing to help however they could. I had some tile replaced in my basement in front of my fireplace and it came out looking amazing. They also did some demo to remove old paneling and put up new plasterboard and did a texture plaster job on the walls. It came out looking absolutely incredible! Also as part of the project I needed to have low dust and not a lot of mess since I have some pets and a young child. They accommodated in spades and did a really good job. 10 of 10 will hire again."

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