"Rebuilt our staircase after an accident fall. There?s no more creaking. It has been reenforced the entire house structure. Their team did an amazing job especially since it landed between all the holidays! It was really a blessing! To have this work done in such a timely manner. We highly recommend and will be in contact for future projects."

"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."

"Carmello and team were delightful to work with. We had a porch deck that was rotting and we wanted it repaired but additionally wanted the porch screened in. The team started right away after hiring. We knew there may be surprises along the way, considering there was rot. Carmello was communicative and flexible to help ensure that our new porch would be safe and solid. Each day, the worksite was left swept and tidy. We will absolutely be working with them again on future projects."

"It went very well. Inson always focused on the highest quality products that would fit the design. Also tried to get each item at the better price. Additionally he was meticulous with the project and **** ** the vendors to make no mistakes and focus on a quality outcome. Finally Inson and his team were diligent to make sure everything was constructed in the right manner. In our case the proper wiring and safest plumbing. Always relied on master builders and plumbers who new what they were doing. The final outcome was above expectations. I would keep in mind any project like ours will cost money - we spent extra with Inson but in the end it was the right thing to do and well worth it."

"My family had the pleasure of contracting John and his crew to remodel our kitchen. We live in a nearly century-old house that was not properly cared for by the previous owner, and our original kitchen showed it. John helped us plan out a full remodel with new cabinetry, countertops, appliances, flooring, and ceiling (the latter two were originally slanted and uneven). He was communicative and thorough during the planning phase and his crew was always on time, professional, and thorough during the actual construction work. John was on site each day to supervise and keep us in the loop on how things were progressing. They caught multiple major structural/functional issues along the way that they were able to fix without it even impacting their timeline for the project. Thanks to John, my family now has a beautiful, functional kitchen. We will definitely be reaching out to him when we start additional projects in our house!"

"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 Dover, 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.
