John and Dorothy Gallagher overseeing the construction of the current John F. Gallagher Co. shop and offices in Eastlake, Ohio. August 1969.


The John F. Gallagher Co. was formed in 1964 by John Gallagher in the basement of his Euclid, Ohio residence. By 1967, the company’s current location was under construction in Eastlake, OH, in 1968 the Eastlake location became its official residence. Early on, the Gallagher company focused primarily on public sector work as evidenced by the fact that the company’s first job was the Euclid public library. By the 1980s the company was beginning to expand from this model, and as a result chose to diversify into mechanical contracting. It began taking on significant private sector work, with major clients such as Avery Dension and TRW and began a service and small projects division which now accounts for a significant portion of the company’s volume. In 1997, John F. Gallagher retired and the company’s management transitioned to his sons.

From its inception, the company has always embraced new technology. It has always been a central tenet of the Gallagher Company that only through the melding of technology and skills would it be possible to deliver a cost structure that is competitive in today’s market place. As such, today the Gallagher Co. has a full suite of technology to assist large development projects. It is the owner of several Autobid Mechanical and Sheetmetal licenses to support state of the art estimation. In house BIM and coordination services utilizing AutoCAD MEP, REvit QuickPen Duct Designer / Pipe Designer, and NavisWorks allow for modeling and clash detection both for design build projects as well as large scale new construction projects.

These tools, bolstered by the company’s onsite certified professional engineering support, allow for a holistic approach to design/build work. The company is able to take on everything from ideation, to clash detection and print generation. In addition, these tools allow for a state of the art pre-fabrication business which improves efficiency, lowers cost, and allows for a safer work environment. To support the pre-fabrication business, the company owns Trembel Total Station robotic locating tools which allows for highly accurate sleve placement, as well as efficient locating of pre-fabricated modules.

Since 2000, the company has grown from a primarily Gallagher operated business. Today, it employs 55-65 people on average, 10-15 of whom are working in the office supporting design / build, estimation, and project management responsibilities. It is capable of completing the largest plumbing projects in Cleveland, as evidenced by some of it’s major work at the VA hospital and the Medical Mart. In addition, the company also has significant history in large scale mechanical contracting projects, such as the Lakeland Community College Health Technologies Building.
