"I recently collaborated with AVSTEP for various home improvement projects, including roof repair, patio door replacement, electrical work, ceiling recess light installment, new flooring, curtain rack installation, water pipe replacement and ceiling replacement. I am extremely pleased with their work. AVSTEP's expertise in roof repair was evident as they efficiently addressed and explained the issues, providing me with confidence throughout the process. The patio door replacement was seamlessly executed, enhancing both aesthetics and functionality. Their electrical work adhered to the highest safety standards, and the installation of recessed lights showcased their modern design sensibility. The new flooring, curtain rack, and ceiling replacement projects were executed with precision, adding to the overall appeal of my home. AVSTEP's attention to detail, professionalism, and commitment to quality make them my preferred contractor for future projects. I highly recommend AVSTEP to anyone seeking reliable and skilled professionals for their home renovations."

"Hubert Construction performed large scale construction/ additions to my home in 2022 and 2024. I had a large addition done in 1998, which I only wish could have been Hubert Construction. It left much to be desired. I watched Hubert work on another house nearby and was impressed. The 2 jobs that they did for me, were absolutely impeccable. Every part of the construction was done exactly as I hoped for, from design, to quality of work, to finished product. That’s why I didn’t hesitate to hire him a second time. In addition, Arthur’s employees are conscientious, sweet, and friendly. They, as well as Arthur, are a pleasure to work with. In summary, you cannot go wrong hiring Hubert Construction. That’s a rarity in the Home Rehab."

"These guys put the ‘master’ back in ‘craftsman’! Once on the job, they are on-the-job! Professionals, they will arrive early, work all day and clean up their mess before leaving. If there’s a question about how to address an issue, they will ask the customer, but always have solutions to offer. Make sure you have all the items you’re responsible for ordered (appliances, counter top, cabinets, faucet, hardware etc.) and in-house, or with delivery dates because you will have trouble keeping up with them once they start! Quality of work is outstanding and always with an attention to detail. The job stayed on budget, all additional work was done under change orders – except one instance. Make certain to ask whether any changes being discussed come under the scope of the contract or are additional work. This is particularly important with sub-contractors like plumbing and electrical."

"We are very happy with how our entire project has been going. Dennis has been in constant contact with us throughout the entire process and immediately calls any time an issue occurs. We had a lot of structural issues that we were unaware of initially until all the walls and ceilings were opened. Dennis immediately called us and discussed how we should move forward. We have 3 very small children and Dennis has been adamant about ensuring our house, both inside and outside, is safe enough for our children. Both his crew and any subcontractor he has brought in has been very professional, friendly and easy to talk to. Dennis holds his crew and subcontractors to a high standard and ensures the job is done correctly."

"Scott and his team did a terrific job. My deck looks infinitely better than it did and it is more structurally sound now than before. He replaced all the decking on the first floor deck, adding a new addition to the deck and completely renovated a screened-in porch. They removed a floating deck on the upstairs deck and resurfaced the underlying fiberglass deck adding new railings. Scott was present throughout the job with his team (3 people). With this job there were little changes that I wanted made and Scott and the team were extremely accommodating and receptive. They did solid work, were very professional and always left the worksite very clean every day. I highly recommend SCS Construction and would definitely use them again in the future."

"Mr. Powers, at first, was courteous and reliable; the project seemed to have problems, and he was getting frustrated at having to surface the existing deck due to its configuration; he claimed that the measurements and figures were off, while another professional disagreed with his calculations; the project was delayed due to materials being delayed by supplier; Mr. Powers suggested another other remedies for steps and that I purchase an additional type of board for $120, which I did; i paid Mr. Powers in full of the understanding that he would come back and finish off certain areas; during this time, a death occurred and he was unable to come when scheduled; when I texted Mr. Powers, he began belligerent, and cursed at me. I do not find it professional to curse at a client and refuse to take phone calls. I ultimately told Mr. Powers not to come back to my house and to refund the board I purchased that was in his possession. He did so. Since the time of completion, May 2026, numerous boards have come loose. I had someone else correct this issue, and now more boards are coming loose, which I texted him about and showed pictures of on September 9, 2026, and have not heard back from Mr. Powers regarding acknowledgment or addressing the loose boards, as my contract provides for two (2) years."

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