"AVSTEP was great to work with, the team started earlier than expected and completely fixed my foundation, not only with replacement block and cement, but added two different types of waterproofing as well. When additional wood rot was found on top of the foundation, they were able to repair that as well without adding more time to the project. The heavy brick and mortar waste from the building was promptly removed like it was never there. Would recommend AVSTEP for future building needs."

"Over a 20-year period, Chatel Construction has renovated almost all the rooms in our two-story house and renovated a two-family rental. Some of the jobs were very complicated, such as installing an exercise pool in the garage. Years later, Chatel was able to convert the space back into a garage when needed. Over the years, business owner Scott Chatel has offered very creative solutions to problems, such as how to protect a wall from pet-dog damage. Provides a detailed written estimate/proposal and adheres to it. Chatel and his crew are creative, reliable, fairly priced, and pleasant to work with."

"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."

"My wife and I are very pleased with the work done by Matteo, Jose, Vicente and Juan. Matteo presented us with reasonable estimates for the two jobs we wanted done. One bathroom was gutted and renovated. It looks absolutely wonderful now. My wife and I provided the materials, but Matt was helpful in making suggestions. Jose added a control panel that now allows us to control water flow to the other bathroom and kitchen without having to turn off the water for the building. The master bedroom/studio was painted and looks great.. Among other things, they fixed a slanted doorway and replaced a door. We'd highly recommend them."

"Started work very quickly. Foreman was great. Tile work was fabulous. Everything looked great in the end. Stuck to the contract pricing. Had to add some additional expenses because I wanted additional work. Did not like the electrician Alfred who took a long time to do his work. Had to visit often to ensure everything was as I wanted. When it wasn't they were quick to change it. The end result was stunning. Nearly everyone who saw the work asked who the contractor was."

"We live in a prewar coop building in Manhattan and were in need of a kitchen, living and dining room/den renovation. Because of the limitations in our building, we were not optimistic that many changes could be made that would dramatically alter the feel/function of the space. Inson Wood proved us completely wrong. With his architectural eye and his impeccable design aesthetic we (and everyone who has been here before and after) experiences our apartment as an entirely different living space. Even family members are shocked at the transformation. I think that what Inson accomplished was the product of a few significant factors. First, Inson asks you what you want and seriously considers how you live. If Inson thinks that different approaches should be considered for what you want, he provides renderings of each option so that you can easily visualize and imagine them. Ultimately, Inson respects your preferences and works with them, elevating them to a level far above what you had imagined. Inson uses the highest quality vendors (whom we NEVER would have found) and expertly guides you through choices (note: follow his recommendations!!!)- our walls would never have had dimension and our kitchen backsplash never have been so unique (two examples) if not for the artisans that Inson uses. Inson is also willing to have you be as much or as little involved in the process as you want to be. I did go with Inson to choose many pieces of furniture but realized after a certain point that his taste point made me confident in him choosing much finishing work (ex: window treatments, decorative cushions, which I love) without me. As with all design work, there are always glitches and Inson was extremely responsive and responsible for taking care of those as they came up. We are nothing less than thrilled to come home each evening and enjoy our space, which feels like a luxurious retreat perfectly tailored to us."

"I used TKT Remodeling Group LLC for a complete basement remodeling. Treon had wonderful ideas about ways to make my basement function more efficiently. He was the only contractor who took the time to discuss ways to remodel the basement that made sense (e.g., moving the bathroom and closet) into spaces that increased our living space. Treon and his crew are friendly, respectful, punctual, professional, and responsive. He even surprised me with a new, functioning fireplace. I wish I had taken before and after pictures. I was able to go to work and leave the workers alone in my home with no problems. Even after my basement project was completed, I called Treon with questions, and he responded quickly. I highly recommend him and will use him again."

"Tony did an outstanding job remodeling two bathrooms in my apartment over the summer. His is very professional and responsive. Our building is old and like any remodel in an old building, we had some complications, but Tony handled these challenges very well and was very attentive to my feedback and priorities. I also want to note that Tony has a good eye for design and in some cases he suggested ideas that improved the overall look of our bathrooms compared to our original plan."

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