Groome Industrial Service Group was founded by Jim Groome Jr. in the spring of 1969. At that time, the company was known was J. M. Groome, Inc. and it operated primarily as a commercial painting company. Soon after, J. M. Groome, Inc. began working its way into other industrial markets and expanding its services beyond just commercial painting.

In the early 90’s, J. M. Groome, Inc. changed its name to J.M. Groome Company and started offering services in the power generation industry beginning in the waste-to-energy and fossil fuel markets.

In 2007, J.M. Groome Company made its move into the natural gas turbine market, performing its first maintenance service on a heat recovery steam generator (HRSG). Two years later in 2009, J. M. Groome Company changed its name to Groome Industrial Service Group and began offering a full line of HRSG maintenance services

Today, with the addition of strategic acquisitions and highly skilled personnel across the country, Groome Industrial Service Group is now positioned as the vendor of choice for most industrial maintenance and mechanical services.

Groome Door & Mechanical Systems (GDMS), originally named Groome Hangar Services Company, Inc., was founded in April of 1979, as Groome’s first individual service company. GDMS focused on the inspections, maintenance, repair, refurbishment, and, if needed, the replacement of hangar doors for all designs and manufacturers throughout the United States. GDMS was best known for delivering innovative hangar solutions for commercial, corporate, and military flight departments.

Today, as part of Groome Industrial Service Group, the hangar door division understands that most door repairs are not planned and need attention quickly if/when an issue occurs. Because of that, Groome continues to deliver 24-hour response times with 24/7 support to facilities throughout the country, like it has for over 40 years.

ExPro (aka Explosive Professionals, ExPro Specialized Services, and Explosive Professionals Midwest) joined the Groome family back in September of 2021. Originally founded in 1995, ExPro provided industrial cleaning services, primarily coal-fired boiler cleaning and slag removal through the utilization of explosives. In addition to their explosive cleaning services, ExPro also added its patented automated hydroblast cleaning services to the already wide range of industrial cleaning services offered by Groome.

The integration of ExPro’s explosive technology and Groome’s experience in the gas-fired power generation space has created what some feel is a game changer in the industry.

Blasting Solutions, Inc. (BSI) joined the Groome family in March of 2023. Originally founded in 2002, BSI provided industrial cleaning services, utilizing controlled explosives primarily to deslag boilers using coal, wood, or fuel oil.

The integration of BSI has helped advance Groome’s customer service in the western portion of the United States and added to its existing customer base in the coal-fired power plant and biomass power plant markets.

Today, as part of Groome Industrial Service Group, the explosives division has become Groome’s fastest growing segment in the company. This has also catapulted Groome to be the nations largest supplier of explosive cleaning services in the power generation industry.
