"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."

"Inson worked with us on our home in the Hamptons and house in San Francisco. He brings an extraordinary combination of very high end style personalized for our tastes; access to special deals from the most elite and sought after designers; and a sense of working within the budget you have in mind. We were able to get museum quality pieces for both homes at unbelieveable discounts. Inson also continues to provide important follow up services as needed. For example, we had a fabric issue with our 40 outdoor chairs that developed after the warranty. The cost to change would have been tens of thousands of dollars but the manufacturer handle the out of warranty issue at no cost to us, which I believe was due to inson’s relationship and advocacy on our behalf. He’s terrific."

"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."

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