Miami, FL — Data Breach Law Group is investigating a data breach involving Mainelli Mechanical Contractors, Inc., reported to the Maryland Attorney General on February 19, 2025. The firm is reviewing whether affected individuals have legal claims arising from the incident.

Mainelli Mechanical Contractors, Inc. appears to be a construction and industrial services firm specializing in HVAC, plumbing, and mechanical systems installation and maintenance. As an employer and service provider, the company typically collects and stores sensitive personal information, including employee payroll records, tax documentation, and client billing details. This data breach was officially reported to the Maryland Attorney General in 2025, confirming that unauthorized parties may have accessed internal systems. If you have received a data breach notification letter from the company, it indicates that your personal information was likely contained within the compromised files. We recommend reviewing the letter carefully to understand the specific scope of the incident and the identity monitoring services being offered to those affected.
