"Above and Beyond Contracting and Bud Moore did truly excellent work. We had to completely redo our entire master bathroom. Bud took the time to walk us through what needed to be done; provided us a fair quote for the work; and then did excellent and beautiful work on the bathroom. We also had him build and install a bench in the bay window of our kitchen which came out perfectly. Bud is great to work. He also is patient answering all our questions and will respond day or night."

"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"."

Customers say: True professional

"I'm that person who has a general distrust of contractors due to a few truly terrible experiences. I blame myself for these bad experiences because I didn't vet the people I hired throughly enough. With the retaining wall bordering my driveway was collapsing and the driveway beginning to split, I knew this wasn't a project I could brush off, so I began an intense search for contractors. Using Angie, I found two contractors I liked for the job, but hired Hector Santucci because he presented a better plan for the restoration of that portion of the driveway that was going to be damaged while removing the old wall. Santucci Brothers has shown me there are good, professional, honest contractors out there, if you just take the time to find them. Hector Santucci and his crew were professional, polite and excellent at their jobs. These are some true craftsmen. Not only is my new wall massive, strong, built to last, but it's quite beautiful. In particular, while the mortar joints on the old wall, which was built by hacks, were three, sometimes as much as four inches wide, Hector's crew tightened everything up, fitting the stones together beautifully, even recessing the mortar on the face. When they were done, they cleaned everything up, power washed the driveway, and even planted new grass. Santucci Brothers stayed on estimate, stayed on schedule, and lived up to everything they had promised me. Communicating with them was easy and efficient."

"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."

"LRL Designs drew the blueprint, designed my kitchen & 2 bathrooms and created a new entrance to my dining room, which created a much more open floor plan in my main floor. I love the way everything turned out and am very grateful for the professionalism and dedication from the designer. She was a pleasure to work with."

"Job: Addition of a family room (design and build) and rebuild of our deck. Reasoning for 5 stars: Douglas is a great listener. As an architect, Douglas listened to our ideas and gave us exactly what we wanted while providing us with expert advice on aspects we were unsure about. Douglas is very efficient in everything he does from drawing to filing with the town. What impressed me most about Douglas was his ability to project manage. Supplies and subcontractors were all scheduled far in advance. The project took place in the middle of the winter and there never seemed to be a day wasted. Douglasâ demeanor makes him great to work with. In March of 2020, it seemed as if the world was collapsing around us. Douglas kept a level head and kept the project moving along making sure all inspections happened before towns began to close their offices. Lastly, Douglas was upfront about the additional costs. He explained the problems, showed us the issues and gave us choices when possible about how to proceed. I highly recommend Douglas and he will be the first person I reach out to the next time we want to do any remodeling to our home."

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