"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 highly recommend Bryan's Home Improvement and Handyman Services. The owner Bryan Grubb was wonderful. He and his staff assisted me in every stage of the remodeling of my bathroom. We entered a contract which they stuck by. The price to perform the remodeling was very, very fair. During the remodeling, a structural problem was found. They addressed the problem and provided me with options to correct the problem. These were structural issues which should have been addressed by their predecessors and was inconceivable that the problem could have been missed. Bryan's handymen, led by Jorge, were professional, timely, efficient, knowledgeable, artistic and neat. They did a fantastic job on my bathroom. I can't thank them enough. I will recommend them to everyone I know. I will definitely hire them again. A+++"

"BelMax did several projects for me including two major projects; (1) remodeling a basement bathroom with the addition of a shower and adding a second-floor addition to the house which became a walk-in closet. BelMax worked with an architect to get a solid design, pulled the permits, completed the work, and got the work approved. I am very pleased with the quality of their work. Throughout the job, the crew wore masks and shoe coverings when they worked inside, which I appreciated. They were also very clear about what was budgeted for each minor project so that later when we changed some of the requirements, we were able to work together to figure out the change in cost. Please note that some of the changes in scope were required. For example, after prior to the work stating, the architect said that we had to add another bedroom window to the house to meet city code. I recommend them and would consider them for work at my house in the future."

"Matt built a sunroom addition for us. We met many contractors before finalizing with Matt and we surely feel good about our decision. Matt's best quality is his flexibility. He wants his customer to be satisfied and happy with the project. He is very energetic and shows care and respect to customer's requests. He is very detailed on his quote. Though all may not finish per the details (in the quote), it is built well and per the code. Matt is personable and will spend time with you explaining and answering questions. His crew is professional, he may though hire helpers for smaller tasks of the project. His framing team is excellent. In terms of timeline, these projects always take longer than planned. Most of the delays are due to scheduling township inspections (and re-inspections). Expect some delays due to Matt's team availability due other projects they are trying to finish. I am very pleased working with Matt for our sunroom project. I highly recommend him."

After spending almost 7 years working to make other companies clients happy, I was able to confidently come to the conclusion that I could not only do it better, but also offer a wider range of services that cater to big and small customers alike. In a world where prices and effects of services are ever increasing, I would like to be the grounded affordable option to make sure that families can get the work they need done and not suffer for it financially. I want to be the one that shakes up the game and makes sure everyone can feel confident and proud of the home they own.

"The best experience I've ever had with a contractor. The owner, Isaias Caceres, provided expert advice on how to complete our project. His workers were highly skilled and courteous, cleaning the worksite at the end of each day. Our finished basement has never looked better than it does now, as a result of this work. This is a company that I'll hire again in a heartbeat."

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