We specialize in customer satisfaction and getting the job done right the first time. Call and deal directly with the owner, Dave Barton. Call for a free estimate and availability. Less Barton Construction, located in Westmoreland County, is a family owned and operated 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.
