"I hired Nicopal Construction to demo and gut my finished basement. It was a horrible dirty job, so I had a very hard time finding a company that would take the job without re-finishing the basement when complete. Vincent, the very friendly owner, came by and provided an estimate. He understood that I wanted to move quickly, so he scheduled the job the following week. I really appreciated his urgency in moving on the project. First day John and Vincent came out to begin work. Don’t let John’s youthful appearance fool you. This young man is a total workhorse! He has the work ethic of a Depression era coal miner. He enjoys hard work, and, just as important, does excellent work. With any project we hit some snags, but Vincent and John were always keeping me updated. In the end; the job was completed and I am extremely satisfied with the end result. Again, special thank you to John. He really did a great job. As with any project, there is a level of stress. I have to say, Vincent was awesome to work with during the whole process. Here’s an example, after work was complete and final payment was made, there was some additional work that was missed (this was my fault and not Nicopal’s). Vincent stayed in communication with me and came back out to complete the work! I have never experienced that level of service from a contractor. Usually once they get their final payment you never see them again. This is not the case with Nicopal Construction. Thank you, Vince! You truly are a man of your word. I would highly recommend Nicopal Construction for any project. We have a few more projects in mind in the future and will be reaching out again. Thank you again guys! I appreciate the hard work."

"Meant to build and display a big Lego city collection as well as letting the kids use it as well. Im sure they’re gonna be climbing on it, it’s got to be sturdy and man this thing is sturdy. The finishing details are awesome and to think this is a utility type project. 10/10 will be getting more made."

"Dave and his company Wise Choice Construction were amazing. They were always on time and finish my back stairs in record time. When they were finish they cleaned up after themselves... nothing for me to clean. Dave also made the process from the beggining to completion so easy and seamless. If I have another project, I definitely know who to call... not Ghost buster, but WISE CHOICE CONSTRUCTION!!"

Customers say: True professional

"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."

"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."

"Lionel came on early to the appointment and spent a lot of time with us. He was professional and went into details, he was very honest. Although we decided to buy another home instead of doing an addition, we will definitely call back Lima for services if we required. Good experience"

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