"We had an idea and the owner, Bud, had a vision!!!! He created an absolutely beautiful outdoor living space.... multiple levels and entertainment areas. The space is gorgeous and every level of detail from the wood work to the design to the layout to the built in bar is just beautiful and functional! Bud provides a level of experience like no other. He is onsite and manages all his subcontractors and expects a superior product which is what he delivered."

"Dave and his crew did an excellent job on my new kitchen! He was very patient with the various co-op restrictions in my building, and all of their attention to detail throughout the job was very impressive. They left the building site cleaned every day and made sure to set things up so I could comfortably live here during the work. As others have said, Dave is a great communicator - I received frequent updates and quick responses via text/email/phone to any questions I had. This was my first renovation as a homeowner, which I was nervous about, and I'm so glad I went with Dave and his crew. I would not hesitate to hire him again and to recommend him to others!"

"I recently had the pleasure of working with Miguel and his team on a major renovation of my house, which took about five months to complete. Throughout the entire process, Miguel was incredibly patient and attentive, ensuring that everything was done to the highest standards. His workers were always punctual, professional, and dedicated to their work. The quality of the renovation is outstanding, and I couldn't be happier with the results. Even now, if I run into any small issues, Miguel is always willing to come by and check it out, promptly fixing any problems. I highly recommend Miguel and his team for any renovation projects."

"If we could give more than five stars to Danny and Champion, we certainly would. We had used them previously for several jobs in our old house, but this time we had extensive renovations done to the kitchen in our new co-op as well as new floors and painting throughout our home. (Before and After photos below). We couldn't be happier with everything that was done. Champion's employees are true craftsmen and their work is impeccable. In addition, they are courteous, professional and perhaps most importantly, RELIABLE. If they say they will be there, they will be there. And when they leave at the end of the day, the work area is cleaner than it was when they arrived. We recommend Champion without hesitation for any home remodeling you many need, and I know when we are ready for our next project we will choose them again without hesitation."

FAQs for addition to existing structure building service projects in Harrison, NY

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.
