GEBRÜDER THEISSINGER GMBH

Gebroeder Theissinger GmbH specializes in the maintenance, repair, and operational support of critical infrastructure systems for U.S. Department of Defense installations. Their core capabilities center on plumbing, heating, and air-conditioning systems, including exhaust ventilation overhaul, water treatment system servicing, and fire suppression infrastructure upkeep. They also deliver industrial machinery maintenance, facility support services, and specialized instrumentation calibration for industrial process monitoring, including burst and leak detection devices. Technical expertise extends to the repair and servicing of commercial and industrial equipment outside the automotive and electronics domains, with demonstrated proficiency in lifting platforms and water softening systems. Their ability to integrate mechanical, plumbing, and instrumentation systems within high-security military environments distinguishes them as a reliable provider of mission-critical facility sustainment services. The contractor maintains a consistent and exclusive relationship with the Department of Defense, delivering sustained maintenance and minor construction support across multiple installations. Work includes recurring servicing of motor pool equipment, water and sewer infrastructure, and facility utilities, indicating long-term, repeat engagement on base-level operational readiness programs. Their portfolio reflects deep familiarity with DoD facility standards, preventive maintenance protocols, and compliance-driven service delivery in garrison environments. Industry focus is anchored in NAICS 238220 (plumbing, heating, and air-conditioning contractors) and 561210 (facilities support services), with complementary work in industrial machinery repair and process instrumentation manufacturing. This positions them as a niche provider of integrated facility systems support, particularly for military communities requiring coordinated mechanical, utility, and control system maintenance. Their vertical specialization lies in sustaining legacy infrastructure under stringent operational constraints. Gebroeder Theissinger GmbH is a small, privately held entity based in Olsbrücken, Germany, with no publicly listed government certifications. Their market presence is defined by direct DoD contract performance, with no indication of domestic U.S. operational bases, suggesting a transatlantic support model delivering technical services to U.S. military installations overseas.
