Get matched with top structural engineers in Haledon, NJ

"My initial review was somewhat marginal, but now several years later I will say that the reinforcement has been perfect, and they did eventually provide the engineered drawings that were promised shortly after the project completion. Only hitch was with the length of the steel, which they did correct by welding on tabs to each end. Ultimately it was a good job and completed in one day. Would definitely use them again if I needed to reinforce a structure."

"My husband and I were very blessed to have Mirek Lewandowski do the drawings for our home addition. We were particularly impressed with his expertise on the subject and thoroughness to deliver the best possible design to meet our specs. We were also extremely happy with the quick turnaround, his good nature and his availability to answer questions. We highly recommend him."

"Joe and team at Three D Concepts did a phenomenal job. Very professional and very knowledgeable in his field. Joe provided insight and ideas that I didn't even think of when starting the project. He was also very familiar with my township and the surrounding areas, which is important whenever doing a home extension. Knowing how to navigate the various zoning laws is so important with something like this. I searched around quite a bit for a qualified architect who is trust worthy. Many wanted to charge a percentage of the construction job. In my opinion, the cost of tile that I choose, shouldn't dictate my architectural costs. Joe provided a flat fee quote upfront. This was a breathe of fresh air and took a lot of uncertainty out of the process. Finally, the quality of work was top notch. We absolutely love the plans that he put together for us. Our dream home will now finally become a reality thanks to Joe and Three D Concepts."

"Had difficult time with town approval but worked through it and completed design."

"Harrison was super thorough, very knowledgeable, a pleasure to work with!"

"Highly professional, knowledgeable and in tune with what I as a customer wanted for my design. Responsive and reliable."

"They were responsive, did a good job, addressed all the question from the local regulators, friendly, and a good quality."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"Professional, on time, very courteous. Would definitely hire again."

"Julian delivered exceptional engineering analysis and design work for my residential gut rehab. He was consistently available, willing to help, and brought strong technical expertise to every discussion. His vision for an open‑wall layout led to the installation of a structural beam that completely transformed the home’s flow and created a true open‑concept space we never thought possible. He worked efficiently, communicated clearly, and carried himself with total professionalism. I highly recommend him to anyone looking to upgrade or reimagine their living space."
