Millennium Tank Maintenance

Millennium Tank Maintenance operates from Brooklyn, New York, as a specialized contractor serving the five boroughs with comprehensive underground and aboveground storage tank services. The business holds credentials as a Licensed Master Plumber, General Contractor, and NYC DEC Approved entity with licensed welders on staff. With a 4.7-star rating gathered from 23 client reviews, the company maintains round-the-clock availability including weekends and holidays for emergency response situations. Services span tank installations, testing, cleaning, repair, and complete abandonment procedures, alongside boiler system work and environmental remediation for petroleum contamination incidents.

What distinguishes Millennium Tank Maintenance from typical HVAC contractors is their dual focus on tank systems and environmental protection. The company operates Millennium Trade School, offering a welder apprenticeship program that trains new tradespeople while maintaining their own skilled workforce. Their emergency response capability extends to oil spill cleanup, contaminated soil excavation, and remediation across residential basements, commercial tank vaults, and open-air sites. All technicians hold OSHA certification and Confined Space authorization, ensuring safe execution of hazardous tank work that other contractors avoid.

Reviewers consistently highlight the company's communication and responsiveness. One client described an oil tank abandonment where the team guided them through every procedural step, while another mentioned technician Israel by name for exceptional service during a cleaning project. Multiple reviews praise same-day scheduling and rapid job completion, with customers noting the team kept them informed throughout the process. A homeowner recounted how Millennium Tank diagnosed their boiler failure within minutes, discovering both a dirty tank and water intrusion that previous contractors had missed, resolving the issue in a single service call.
