What Carylon does

Carylon is a privately held environmental infrastructure maintenance services company founded in 1949 and headquartered in the United States. Operating through 14 specialized subsidiary companies and 25+ locations, Carylon provides a broad suite of services including sewer and drain cleaning, CCTV sewer inspection, industrial cleaning, high-pressure water blasting, hydraulic dredging, hydro excavation, pipe rehabilitation, and emergency response for municipalities, utilities, and Fortune 500 industrial companies across all 50 states.

The company's core technical capabilities are anchored in proprietary equipment and decades of operational know-how. Carylon pioneered the use of closed-circuit television (CCTV) for sewer line inspection and operates specialized heavy equipment including hydraulic dredges, ultra-high-pressure water jetting systems, and vacuum trucks. Its service portfolio spans routine maintenance (sewer/drain cleaning, grease trap servicing), specialized industrial work (chemical, refining, power generation facility cleaning), and emergency response (hurricane, flooding, and disaster recovery). The company maintains a 1.7 EMR safety rating, indicating industry-leading safety performance in a capital-intensive, hazardous-services sector.

Carylon's business model is project- and contract-based, generating revenue through service contracts with municipalities (sewer and water utilities), investor-owned utilities, and large industrial operators in oil & gas, chemical, refining, power generation, steel, and manufacturing. Named customers include BP and the Orlando Utilities Commission. Job sizes range from approximately $150K for routine municipal work to $4M+ for large industrial turnarounds. Pricing is likely on a per-project, per-hour, or per-linear-foot basis typical of the sector. As a private, family/employee-owned enterprise with 1,000+ employees, Carylon competes on national reach, equipment specialization, safety record, and 75+ years of institutional client relationships.
