"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."

"Mike went beyond his service. He replaced my concrete patio and place it with paver tile stone. He paint my bathroom and put up new light fixtures and fixed my wood kitchen floor. He built a beautiful deck. Very nice experience working with Mike. Not disappointed at all. Very nice man"

Customers say: Quality work

"We hired Ernest and Sons to construct our patio tiles. We purchased 2' X 2' Tiles and I have to say they did a gorgeous job. I was so pleased with the way they showed up when they said they would. The men that laid out on my job worked so hard. The labor was very strenuous but they never took a break. They were the most conscientious and polite workers I've ever dealt with. They worked neatly, cleaned up totally afterward, and just had a great deal of respect for our property. They really did a beautiful job and Ernest, the owner is a real gentleman also. Love this company!"

"Atlantic 1 and Eddie were referred to me by another happy customer who in return was also referred by someone who used their services. Quick to quote and book (especially when we had a water damage project and couldn’t wait around) , not afraid to take on challenges that other contractors wouldn’t work on, fast turnaround and good pricing. Would I use them again?: I’ve done a kitchen remodel with them, then a living room- from ceiling paint to floor install to closets remodeling, and I’m having them return for a quote on deck / balcony and gazebo reconstruction and new fence So yes.. I would definitely use them again!"

"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."

"I had an excellent experience with George. He was professional, communicated effectively, and was very responsive to text messages. George took the time to thoroughly show me how to use my new TV console, which included a fireplace, making sure I was comfortable with all its features. I highly recommend his service!”"

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