"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."

"Having had work done in my home from small tasks to significant renovations I have encountered several contractors who perform marginal or substandard work so I decided to source a reputable contractor from Angi. After reading the comments and reviews, I arranged a personal meeting with Mike Melia for my bathroom renovation. Mike responded quickly to evaluate and explore and explain the best options while taking into consideration my handicaps. Throughout the project there was much infrastructure from prior work performed and existing conditions. Mike addressed all structural problems, plumbing and electrical repairs including a new sub panel. Mike has remarkable attention to detail for every aspect of work and he completed the work with a high standard of professionalism with his employees and subcontractors. Mike was on site everyday in constant communication with myself and my insurance company. He was unexpectedly neat and clean throughout the process. This very challenging project could not have gone smoother. He is personally knowledgeable and takes pride in his work. I would highly recommend Mike and his team. I am now using Mike and his team to build a full deck and to make structural repairs to my garage. I hope my experience inspires others to contact Mike Melia when it comes to finding value versus price. Not the lowest bidder, but worth every penny to have all aspects of service completed to a high professional level. Mike also went above and beyond not charging for several tasks! Mike did the most professional and comprehensive work ever done in my home! Richard Dunn Nutley New Jersey"

"Carmelo and his team SET THE BAR for responsiveness and dedication to customer satisfaction. Legacy remodeled the front of our house, including a new front door, building a portico, fixing structural damage, siding, and window framing. Transparent every step of the way. Carmelo was flexible with decisions involving sourcing materials and was informative about our options as we made decisions throughout the project. We will be repeat customers in the future; I would trust Carmelo and his team with any project!"

"We had a great experience with Giove Renovations for our recent addition. The work was so well done, all inspections were passed on the first round, they were incredibly neat and finished before we expected them to. They gave us a timeline of 4-6 months to add on a family room, kitchen, bathroom, pantry and make modifications to the existing layout. We figured 4-6 months meant more like 6-8, but they finished in exactly 5 months from the first dig. Luca and Antonio are perfectionists and were very accommodating. Most importantly we felt they were very honest and trustworthy. We will definitely be calling Giove to do the next phases of our project."

"Hasnain and his team at Wa did a 2nd level addition and remodel of our ranch. We were on a tight schedule and they did everything they could to get us home on time. During covid, with many supply issues, this was no easy task but they pulled it off."

"Angelo is great and is willing to go above and beyond your expectations to give you a great look and experience with the contracting job. He is a responsive contractor and if he misses you, he will follow up right away before the job gets started to make sure that all the plans are set. He is present and constantly checking in with the clients and the contracting crew to make sure things are going as scheduled. When the work is completed making sure that everything was to my liking. everything is going well. His team works very well and are focused on the details. They made sure to get all the right materials for the job, to the right of flooring and grout for my shower, to the best kind of paint and the color scheme that works best in a finished basement During a painting job when I asked what works best from a contractors view Angelo gave me a suggestion that made the rooms look even better than I thought it would. He is always working to give you best outcome for any job he takes on. I highly recommend Charles Renovations for any contracting work. Angelo and his team are exceptional!"

"They are not local to my area. Please, hire local. And this is for Angi: Try not to recommend contractors who are a significant distance away, in this case around 80 miles (and 2 states) away. Great website, appears to be professionally designed and maintained, I like what they do (judging from the content in the website) but I am outside their service area. I don't live in that area. If I owned a home or apartment in that area, I would hire them."

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