"Hired Built-Well to build a new oversized 2-car detached garage with several custom features such as utilizing steel I-beams and plywood inner walls. Also had Built-Well install new roof shingles and siding on my house to match the garage. Communication with Grant was great and he was very responsive to all my questions and details that I wanted addressed, along with being flexible on some add-on work/changes. Project was completed on budget as per the quoted price."

"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"

"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."

"It went very well. They are very good. Their timing is great. There have been a couple times when my son was parked in the driveway and we had to reschedule but it was no problem. Every time they come out they make sure everything is done. They are very fast. The service is super!"

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