"After hurricane sandy in 2012 a lot of people in Brooklyn and Long Island got flooded a lot of home owners received flood damages or lost their property due to Hurricane Sandy... I am living on Cony Island Seagate area at that time I was home with my Family and how a remember the water came up to my house and flooded my basement and first floor of my house... I was very scared and desperate.... We basically lost everything at the first and basement floor...
We have received some help from FEMA like every homeowner in that area but the rest was huge loss from our pockets...
We found structureline based on recommendations and we started to do renovation...Nicholas the General Manager helped us out to apply for a small loan so we could begin the renovation...We needed to do a complete house renovation ....
They took off the walls in the basement and 1st floor, they did mold disinfection, replaced all drywall's, wiring, boiler, windows, doors, siding etc..
They did remodeling on the master bathroom from the first floor and kitchen, they did a wonderful job...We love their new engineered Hardwood floor and the new design of the bathroom with the big bathtub and shower cabinet ... The price we spend ed was a little higher than we were expected because we did some design work in the living room and Kitchen but for sure it worth it....If Someone will ask me for a recommendation for sure I will recommend Structureline because they helped me out at that time ....Thanks"

"The town required structural drawings for the retaining wall around my pool and after speaking with and getting estimates from several Structural Engineering companies choose Magnus Engineering. The company was responsive and willing to provide the service quickly. James Strizki was the engineer; he was professional, patient and reassuring. He continued to follow-up even after receiving payment until I had the final inspection. They were reasonably priced and delivered the required signed sealed documents allowing me to finally close out the permits that were pending from the year before."

We are an engineer's engineer offering structural engineering and vehicle parking design services. Our experience illustrates an ability to provide simple, innovative solutions to unique conditions which separates us from cookbook designers. Instead of overly conservative designs that lead to inflated construction costs, we provide designs that satisfy economic, aesthetic, and performance requirements. \n\nThornton Engineering specializes in the structural design of prestress concrete and total prime design services of parking structures, but our record shows a broad range of building types and construction techniques in our designs. In keeping with our philosophy of innovation, we do not use generalized "canned" computer design programs written by other engineers. Rather, the responsibility we have to our clients has led to the development of our own design programs.
