They completed our addition in a time manor and we could not have been more pleased with the outcome.

"Hired Built-Well to renovate our downstairs powder room, install mouldings in our dining room, and add onto our existing deck. They were extremely professional and worked with us with some of the changes to our plans that we threw their way. Everything is beautiful and they were a pleasure to work with."

"My parents and I live in a old brick apartment building in Hoboken that is from the 1880s. The bathroom in our apartment had not been updated since the 1940s. We needed help ASAP. We checked out Cesar s page and wanted to hire him immediately. The reviews speak for themselves. When he came into our apartment to give us a quote we knew that this was contractor we needed to get the job done. Cesar is affordable, friendly, and very accommodating to any issues or concerns you have before starting the project. Two massive issues with our project were that my dad has spinal & walking issues, so we needed the floors clear of all tools and materials at the end of the each day so that father could walk efficiently through the apartment. The other big issue was that we only have 1 bathroom, so Cesar agreed to work with us on pulling the toilet off and on as every day finished so that we did not have to leave our building to use the toilet. Him and his crew are the best and take pride in their work so that owner is happy with the final result. We brought the bathroom down to the bare bones and rebuilt it back up. I worked with him every step of the way to make sure that he needed all materials to get the job done in the time we needed. This project was an intense remodel with some of the hardest demo and substrate materials that an old bathroom can have. He didn t think anything of it. He has veteran experience in the field and this remodel only took 3 weeks. We are very impressed with Cesar s craftsmanship and professionalism and we will be hiring him again for any future interior projects."

We were kept informed Every step of the way and Bill had every worker there on time and it flowed beautifully. That’s an art! Everyone worked well together and they were very neat. We have finished the work and we couldn’t be happier with the way it turned out. We have received so many compliments on our rooms. I highly recommend All Star of HC."

"Carmello and team were delightful to work with. We had a porch deck that was rotting and we wanted it repaired but additionally wanted the porch screened in. The team started right away after hiring. We knew there may be surprises along the way, considering there was rot. Carmello was communicative and flexible to help ensure that our new porch would be safe and solid. Each day, the worksite was left swept and tidy. We will absolutely be working with them again on future projects."

"Emile is a great contractor and I highly recommend him reservation to anyone looking to upgrade or do a home renovation project. He helped us renovate our primary bathroom (completely, down to the studs and completely changing the layout), created a main floor laundry room, and an extra bedroom. Emile provided a comprehensive estimate, which was accurate, and he finished the entire job within the agreed upon time frame within the estimate. His crew were complete professionals, polite, and did excellent work. We could not be happier with the results and our new spaces. The rooms are beautiful. He went above and beyond in all respects, even when I decided to make changes to the design along the way, he was able to roll with them and told me how much various options would cost and other pros and cons of those options (tiling the whole bathroom vs partial, heated floors or no, different types of fixtures, etc)."

Customers say: True professional

"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."

FAQs for addition to existing structure building service projects in Whippany, NJ

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.
