Working with Louis was very pleasant experience. I needed Hydraulic calculation done quickly and, sure enough, he did the calculation right away just in time for me to turn it over to DOB. Would recommend him to anyone who needs reliable partner in making sure your job is done on time.

Louis was super professional and literally a life saver. There was a FDNY violation that needed to be addressed and was serviced immediately. Not only did LL Engineering get the job done within a weeks time, but also pointed out a bad quote from another contractor where it would have costed 4 times the amount. That reason was because, i was being mislead to procure work that was not necessary. I was being manipulated by the previous contractor(s). Louis was honest and correct about the work order. In the end, everything was done flawlessly and precisely. Highly recommend.
