"The best! Keith, Hank, Michael and Grant were a pleasure to work with over the course of several months last year. I have dealt with many contractors, both personally and professionally, and I can tell you that they should be your first call on any project. The work was done on time and on budget. We added some things to the project, but in no way did they push us to add a single additional item. In fact, we added a complete rebuild of the deck after the project had begun and there was no premium on the additional cost as compared to other contractors who know they have a captive audience. They were present at the property nearly every single day of the project, including Saturdays, as opposed to other contractors who simply give the work to subcontractors and check in once or twice a week, at best. In other words, they know what is going on at all times and are able to give guidance and direction to the subs, and us, on site. They are also more than willing to listen and make any adjustments without crushing you with additional costs! And, they actually work and work hard (especially through the brutal, brutal summer heat last year when we lost our air conditioning for a couple of weeks). I have known Keith and the crew for many years and there is nobody else I would trust to complete such an extensive project which included: completely new roof, all new siding, replacement of every single window in the house (which Keith, Hank, Michael and Grant) did personally, new addition (which included replacement of primary first floor structural beam), new primary bath and primary closets, new flooring, whole house painting including ceilings and more. Lastly, they don’t bite off more than they can chew which sets them so far apart from every contractor we have ever dealt with. Personal touch, presence, attentiveness and excellent workmanship. Highly recommend!"

"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 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)."

"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!"

"Wonderful service! Main job was replacing lateral file drawer supports. My wife noted that we had addition small problems with kitchen under counter lights and a utop hat light in another room. All the work got done very quickly and very well. All 3 jobs were more that satisfactory. We were very pleased with the quality, care and cleanliness of all the work done by Matt Pickford, and look forward to future opportunities to use his services."

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