"They were very easy to work with. They ended doing some additional work for us at my house. They are one of the only companies that my wife and I both agreed that we would like to come back to do any additional work."

"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 hired Alan to handle the renovation and expansion of our house, which included adding a second floor and building an addition. After meeting with various contractors, Alan stood out to us. He was not only highly professional but also made us feel a personal connection. Alan was very transparent with his quote and conscientious about the costs of "change orders" throughout the renovation. He dedicated his time to managing the entire renovation, from demolition to completion. True to his promise, we were able to move back into our home within seven months. We love our new house! Alan turned our dream house into a reality for our family!"

"Mike did a fantastic job! I initially reached out to him to paint an apartment and wound up having him also replace a kitchen and renovate a bathroom. Both results exceeded my expectations! Great attention to detail."

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