Cook & Krupa is a commercial general contractor and Certified Butler Builder® based in Mineola, NY, serving Long Island and the New York metro area. We provide both conventional construction and Butler® pre-engineered metal building (PEMB) solutions, giving owners and design teams a single partner for work that demands careful planning, system coordination, and long-term performance. This integrated approach reduces handoffs, streamlines communication, and delivers greater efficiency from design through construction.
Founded by Raymond J. Cook and Steve Krupa, Cook & Krupa grew from a small carpentry shop near Manhattan’s 59th Street Bridge into a trusted regional commercial construction firm. Built on steady work, repeat clients, and straightforward problem-solving, our projects expanded in size and complexity over time. What hasn’t changed is our foundation: quality work, genuine relationships, and doing what’s right.
Our Leadership:
John Cook & Richard Morandi
Our leadership reflects the continuity and evolution of this history. Owner and President John Cook, son of co-founder Raymond J. Cook, brings decades of hands-on commercial construction experience, guiding projects from early planning through completion. Vice President Richard Morandi adds deep industry knowledge that supports the firm’s work in both conventional construction and pre-engineered metal building projects. Together, they lead Cook & Krupa with a steady, collaborative approach, carrying the company’s story forward while continuing to strengthen its technical capabilities and service to clients.
Strategic Growth:
Cook & Krupa Merger with
Stuart Berger Construction
In 2019, Cook & Krupa merged with Stuart Berger Construction, a respected firm known for Butler® pre-engineered metal buildings. The merger brought that specialization in-house, strengthening our technical depth in PEMB systems and expanding the work we deliver within a single organization. The Butler® PEMB expertise and project experience once associated with Stuart Berger are now carried forward by Cook & Krupa under one name. While the Stuart Berger name is no longer used independently, its influence remains woven into our capabilities and history.

See how Cook & Krupa streamlined project coordination, integrated PEMB expertise internally, and evolved into a more unified delivery partner.
With in-house PEMB expertise and design-assist capabilities, Cook & Krupa engages earlier in planning and pre-bid phases to help align design intent, structural requirements, constructability, and budget expectations before construction begins.
This proactive approach helps identify challenges earlier, reduce disruptions during construction, and create a smoother transition from design through execution. What evolved was more than expanded capability. Cook & Krupa developed a more coordinated delivery model designed to reduce fragmentation, improve responsiveness, and support more efficient project execution for complex commercial construction.
