"Anthony Nastasi of NB Woodworks, LLc, has our highest recommendation. He has worked with us over the past year on a variety of projects aimed at refurbishing and improving our home. This has included exterior trim replacement, replacing a box window with a French door and side light unit, and replacing a large unusually sized window. He also built a beautiful mahogony deck. Indoors, he installed a french door which included fine trim work. In addition, he hired excellent subcontractors to powerwash and paint our home and build a patio, porch and walks. We highly recommend Anthony's carpentry skill, as well as his problem solving, planning and coordination skills. He is also a dependable, honest person of fine character."

"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."

"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."

"Very well. Mark is extremely responsive. I had a clear vision of what I wanted to do and Mark was able to get me to a great plan with about three iterations of the plans. Also Mark's plans were approved without revision by the building department which is not easy to do where we were building."

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