"I contracted Black Stallion Enterprises LLC to replace the roofs on two of my houses. The entire process from the initial estimate to completion was fair, easy, transparent, and professional. They arrived promptly, completed the job on time and within budget. The workers were clean and worked full days with minimal disturbances to our everyday activities. Joe oversaw the job and provided step-by-step updates, explaining what was being done and the reasoning behind it. Additionally, where things were not done properly by the original builder, BSE added the necessary products and fixed it, all within the original price estimate. The roofs look beautiful, and we are already seeing efficiency as a result of the replacement. The BSE team followed up after completion to ensure we were happy. They definitely stand behind their work and materials. I highly recommend BSE for all construction projects and will hire them again."

"I was initially very happy with the work and the progress being made on the two bathrooms but as time went by, the project was being neglected as, I assume other jobs took precedent and the communication became nil. The plumber was a disaster making multiple mistakes and leaving a filthy mess behind after working in the house, including leaving tools on our bed and the old toilet in the bedroom, rather than bringing it to his truck or the basement. The job kept dragging on and as it did, Mike was getting more frustrated and angry with us! He had two workmen, one of whom always smelled of alcohol and was constantly having health problems. After months of labor and bad feelings between us, I wanted the job done and the workmen gone, even though my shower does not drain. Now, every time I take a shower, I have to kick the water into the drain with my foot and soak it up with a wash cloth which takes time. It is infuriating after all the money I paid and the incredibly long time it took."

From concept to completion, Capizzi Home Improvement has the experience to handle any custom home renovation whether it is interior or exterior. We are a trusted full-service home improvement and remodeling company serving Cape Cod and the South Shore.

"After many years of Indecision we recently concluded it was time to put in a new kitchen. From cabinets, floors, walls, ceilings, appliances and finally painting - the works!!! We chose Capizzi Home Improvement Company. We had heard they were excellent and had a great reputation for customer satisfaction. We had no idea of the scope of the job and all the work they would have to accomplish. Needless to say this was a very smart choice on our part. From the start there was our designer Diana then to the Caroenters, Jimmy and Dave, the Electricians Dave and Andrew, the Painters Joshua, Jesus and Freddie and the Plumbers Bill and Charlie - all contracted through Capizzi. All were fantastic at their trades. Very professional and knew what they were doing. All of the above coordinated through Gary who managed it all! I would recommend this crew from top to bottom. What a great job they all did! Super, super, super. Kudos to all! P.S. Highly Recommended!!!"

FAQs for addition to existing structure building service projects in Barnstable, MA

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.
