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!!!"

"Carlos and his team worked quickly and efficiently to install 4 ft high lattice fencing around my vegetable garden. After it was installed I realized it was way too tall for my backyard ( my fault for niot realizing this in advance). They returned promptly and cut the fence down to 2 ft. ( at a reasonable cost). Now it is just perfect and I love it. The team was pleasant and easy to work with. I highly recommend this company!!"

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