Groome Industrial

What Groome Industrial does

Groome Industrial Service Group, founded in 1969 by Jim Groome Jr. and headquartered in Denville, New Jersey, is a privately held specialty industrial maintenance services company operating across five service divisions: Catalyst Services (CO catalyst, SCR catalyst, and Ammonia Injection Grid lifecycle management), Explosive Services (including the patented KinetiClean kinetic shockwave HRSG tube cleaning technology and controlled explosive deslagging), Vac & Water Services (automated hydroblast, vacuum truck, and media blasting), Mechanical Services (HRSG maintenance, boiler repair, hangar door services, and the in-house Groome Welding School), and Painting & Coating Services (industrial coatings and Groome Paint Shop). The company serves power generation (natural gas combined cycle, coal-fired, waste-to-energy), refinery and petrochemical, aviation, municipal, and manufacturing customers through turnkey project delivery with in-house labor crews, supported by 15 regional offices nationwide.

The company generates revenue primarily through project-based professional services contracts, outage and turnaround engagements, and emergency response work, with supplemental equipment and materials supply (catalysts, replacement parts, coatings). Pricing is quote-based and varies by project scope and duration, with field labor rates starting at $18-25/hour. Go-to-market is direct enterprise field sales led by a Chief Revenue Officer, augmented by content marketing through case studies, blog articles, and webinars demonstrating quantified service outcomes. The company holds multiple regulatory certifications that create competitive barriers, including ATF Federal Explosives License, ASME R-Stamp, SSPC/NACE affiliations, and NCCER accreditation.

In September 2025, Groome was acquired by private investment firm Ariel Alternatives, which has stated intent to fund further acquisitions. The company has pursued an active M&A strategy, completing or announcing five acquisitions between 2021 and 2026 (ExPro, Blasting Solutions Inc., W-S Companies, and Taylor's Industrial Coatings) to expand capabilities in explosive cleaning, mechanical services, and coatings. The Siemens Energy 'Preferred Partner' endorsement for HRSG maintenance and EPRI validation of KinetiClean technology anchor its credibility in the power generation segment.
