We take great pride in offering the best possible experience with our expertise, quality, and customer service. In order to understand the needs and expectations of our clients; we take great care to work and communicate with everyone in a professional manner. It is our mission to exceed our clients expectations by providing excellent workmanship and complete customer satisfaction, from the start of each project to its completion. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"Despite careful research to find and hire builders/remodelers to do a variety of jobsâ a kitchen remodel, bathroom remodel, and farmer's porch addition, to name a fewâ we have always been frustrated with the process and/or disappointed with the results. However, this is not the case with Joe Perullo! Joe and his team are AMAZING as they completed a new master bath, a new master closet, an outdoor shower, and a basement remodel! 1. Joeâ s communication is clear and frequent. He informed us of the plan and the timing of it and followed through with the plan. 2. Joe is a great listener. He understood what our vision for these projects was and he made the vision a reality. 3. Joe is committed to ensuring the customer is satisfied with the result. He checked in frequently to make sure the work met our expectations. 4. Joe is responsive to the needs of the customer. If we had a question or a change to be made, he eagerly addressed the question and/or made the change. 5. Joe and his team are experts in their craft. Whether it is painting, plumbing, tiling, or fine carpentry, the results have been above the expectation. 6. For all of his great work, Joeâ s prices are fair and reasonable. We highly recommend Joe Perullo for your next remodeling project!"

We have served thousands of homes on Cape Cod since 1976. 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!!!"

Addition to existing structure building services FAQs

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
