Guardian Fire Protection Services (“Guardian” or the “Company”), a leading provider of fire and life safety services, today announced that it has acquired Harris Fire Protection (“Harris“). Terms of the transaction were not disclosed.


Guardian is a premier provider of commercial fire and life safety services and a one-stop source for all fire protection services spanning engineering and design, inspections and testing, and ongoing repair and maintenance. Guardian’s comprehensive suite of market-leading services, localized service delivery, strong employee culture, and highly skilled, trained, and efficient technicians underpin the Company’s excellent reputation as a leader in the industry. In January 2024, Guardian partnered with Knox Lane to support and accelerate the Company’s growth objectives.


Founded in 1971, Harris has built a legacy as an exceptional fire protection services provider with an emphasis on special hazard fire suppression systems for commercial and marine industry customers. Based in Baltimore, Maryland, the addition of Harris’ deep expertise and best-in-class team enhances Guardian’s presence throughout the Mid-Atlantic region while bolstering the Company’s services offering.


“We are thrilled to welcome Harris to Guardian and enhance our special hazard and marine fire suppression capabilities,” said Scott Agge, Chief Executive Officer at Guardian. “The Harris team has established a reputation for exceptional service and urgency. I am confident that together, we will be even better positioned to deliver best in-class, comprehensive solutions for our customers. This marks our first acquisition since partnering with Knox Lane earlier this year, and we are excited about the many growth opportunities ahead.”


Leveraging Guardian’s extensive resources, Harris’ dedicated team of fire protection professionals will continue to serve its customers under Harris’ existing brand and leadership team.
