"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."

"We had an excellent experience working with Bill and most of his crew on our home addition project. AllStar stood behind the quality of workmanship, which met our expectations. The crew was courteous, respectful of our home and most dependable. The Addition blends seamlessly with our existing structure and we couldn’t be happier with the final result. We highly recommend AllStar to anyone looking for high quality and very reasonable home renovations project."

"TNN managed our new construction and land development project from scratch. Tim caught MANY errors by the Engineer and Architect before they could become a problem. He made many great suggestions to elevate our original plans. Work quality is great and they take pride in everything they do. Nick did an amazing job on our trapezoid windows and carpentry work. We highly reccommed TNN and will continue to use them for the next phase of our project (garage) We would be happy to provide a reference and even show the work they completed for our project.

"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."

"I have used Structureline few time in the past It all begins with a bathroom Remodeling when I used to live in Jersey City... I Hired them Based on recommendations and good reviews... The story was that at that time 2009 I couldn't find a good Licensed Contractor to get the management  board approval in my building, because of the high requirements.. And my sister Gina give me the contact information of Structureline as certified contractor.. After they pass the board they did the bathroom remodeling and I was very happy with their results... After I moved to Brooklyn my husband said that would be nice to hire a contractor  to do a extension to the house.. After we received several bids from different contractors even that the price was a little higher we decided to go with Structureline because we already knew their work.. Nicolas advised us to build a second floor instead of the back extension and we thought that is a brilliant idea and went for it...
To tell the truth the construction took longer then we expected .....a lot of paperwork, inspections for framing , plumbing  we did received a violation because we haven't  used the scaffolding  properly weather conditions etc...
But we know that Nicolas did the best to finished and we do appreciate that... My husband was very happy wen the construction was completed, a lot of closets room, master bathroom, Large windows , big living room and huge living room...
I really liked bout their renovations that the walls a straight and smooth like glass, defiantly is recommended to see ....

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