"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."

"Excellent. Dave Perrotta, Westbrook Contracting, LLC, was recommended to me by a friend. I am so happy I took her advice. Over the past two years, Dave and his crew have done a beautiful job completely renovating my kitchen and adding a small addition to the side of the house, which included a full bath and closet. The painting was excellent and not only did they paint the dining room, but they fixed the doors to my corner built-in hutch, so they actually close and stay shut. I have received many unsolicited compliments on both the inside and outside work and best of all, the house is just so much more comfortable to live in. I asked about putting a few clothes hooks in the small hallway for rainy day weather, and they built me a beautiful clothes rack, which gets so much use! The shower needed a glass door, something I had never purchased before. Dave not only suggested an excellent vendor, but assisted in the selection. Dave is very easy to work with and his crew is not only skilled but I am very comfortable with them in my home. In addition to his crew, I have been impressed with the quality of sub-contractors, vendors, etc., he used. In closing, my grade school neighbor said it best: "the new addition looks like it was always there"."

"Miguel Tapia the owner was outstanding. He promptly followed up his initial proposal and we reach an agreed upon price. His crew was hardworking, neat and professional. I was impressed with their prep work as the took the old paint down to the wood base. They painted around numerous flower beds without disturbing anything. I was so impressed with their work, I had them repair and paint some wooden shingles on various areas of the siding of my house. Very pleased with the work and the cost."

"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."

"Tito came himself for the appointment to discuss the job and the subsequent proposal. He is fair, honest and the people he sent to do the job were true craftsmen. The work was excellent, neat and on time. I recommend Tito unreservedly for house painting, deck staining and minor masonry repairs."

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