By the beginning of World War II, they had purchased their seventh crane and were loading military equipment bound for Europe to support the Allied Forces.

The company performed salvage and dredging work, installed navigational aids for the United States Coast Guard, and even constructed a breakwater to protect the air shaft leading from the Brooklyn–Battery Tunnel to Governors Island.

They also became the prime contractor assigned to remove abandoned wooden vessels for the Army Corps of Engineers, work still contracted today.
