"We are very pleased with the new deck build by Bryan and his team. They first tore down the old deck to the frame, which was still in good shape. They then rebuilt the deck. They replaced the floorboards, the side railings and boards, and the steps. It looks great and is very solid. See attached pics."

"My basement got flooded during IDA, after contacting with couple of contractor I met with Matt, He came on time and explain everything what needs to be done also provide a reasonable price. He started to work immediately with his team. His work was very professional, he did everything as he promised and completed the work on time. He was the most professional, clean and trustful contractor I have met so far. He was always top of the every process and he was paying attention to every small details even I didnâ t see them during the construction. I highly recommend him, I also started recommending him my friends. I will 100% contact him even if I have a small project in the future, Thank you Prestige Design and Build for Beyond Expectation."

"I recently hired this contractor to address some serious structural issues with a garage, and I couldn't be more pleased with the results. The garage had been showing signs of deterioration, particularly in the footings, which raised significant concerns about its overall structural integrity. From the initial consultation to the final inspection, the contractor and his team demonstrated exceptional professionalism, expertise, and attention to detail and were willing to work within the constraints of a modest budget."

"It went very well. Inson always focused on the highest quality products that would fit the design. Also tried to get each item at the better price. Additionally he was meticulous with the project and **** ** the vendors to make no mistakes and focus on a quality outcome. Finally Inson and his team were diligent to make sure everything was constructed in the right manner. In our case the proper wiring and safest plumbing. Always relied on master builders and plumbers who new what they were doing. The final outcome was above expectations. I would keep in mind any project like ours will cost money - we spent extra with Inson but in the end it was the right thing to do and well worth it."

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