"I hired Anton to work on a small, but fairly complicated remodeling job. A partial wall was obstructing my living room and he installed a new beam to open up the space. Throughout the process, he was responsive and communicative to ensure that we were on the same page. The work was done slightly faster than expected and most importantly, the quality of the work was excellent."

"Hiring a contractor can be challenging. Let me simplify the process for you. Hire Above & Beyond Contracting for your next home project. Bud and his team just renovated our basement and we couldn’t be more satisfied with the experience. They turned our cold, dark basement into a bright entertainment room with a sports bar. They brought our vision to life on schedule and on budget. Bud is extremely talented, knowledgeable and responds to text messages within minutes. When he tells you that he’ll be at your house by 8:00 AM, he’ll be there at 8:00 on the dot. He truly cares about the quality of his work and treats his projects as if they were being done within his own home. After spending 4 months working with him, Bud isn’t just our contractor for the next project…he’s a friend."

"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"."

"I recently closed on my new-build condo in Stuyvesant Heights area of Brooklyn this past March 2023, & needed a local general contractor to execute a long list of works to bring my designs for the unit to life & add some character to it. When I contacted Waxtel LLC, Dave (owner) priced the large job I requested (general contractor, electrical, and plumbing works) reasonably within my budget, was very responsive, & kept communication clear. Rich (PM) helped support the contractor team in execution of the works, but myself/husband did have to handhold some of the contractor works to ensure it was done on time & met our quality standards."

"Santucci did our original patio, which we are still happy with, and we recently added an extension. The work is meticulous and the plans well-thought out. Hector was honest about his availability and timeframe, and the work was completed on schedule. I would definitely hire him again and would recommend him to others."

"The work went exceptionally well. The work was professionally done and completed within the original estimates for time, cost and schedule. The work included repairing of plaster, painting of walls, floors and ceilings. Also a problem with existing shingles on the roof was repaired. Several good suggestions were made and used as to the materials to be used and how to best perform the work."

"Gustavo Lojano is a skilled carpenter and extremely knowledgeable in all areas of construction. He takes pride in his own work and expects the best from the other craftsmen on his team. He isn’t happy unless his customer is happy. He recently did a complete bathroom renovation for us. His suggestions made the finished product even better than we expected. Additionally, he corrected some work that had been done incorrectly in the past and would eventually have caused us problems. His prices are fair and well worth the money considering the quality of his work."

"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."

"It went very well. Inson always focused on the highest quality products that would fit the design. Also tried to get each item at the better price. Additionally he was meticulous with the project and **** ** the vendors to make no mistakes and focus on a quality outcome. Finally Inson and his team were diligent to make sure everything was constructed in the right manner. In our case the proper wiring and safest plumbing. Always relied on master builders and plumbers who new what they were doing. The final outcome was above expectations. I would keep in mind any project like ours will cost money - we spent extra with Inson but in the end it was the right thing to do and well worth it."

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