"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."

"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."

"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)."

"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!"

"We hired Ernest and Sons to construct our patio tiles. We purchased 2' X 2' Tiles and I have to say they did a gorgeous job. I was so pleased with the way they showed up when they said they would. The men that laid out on my job worked so hard. The labor was very strenuous but they never took a break. They were the most conscientious and polite workers I've ever dealt with. They worked neatly, cleaned up totally afterward, and just had a great deal of respect for our property. They really did a beautiful job and Ernest, the owner is a real gentleman also. Love this company!"

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