Walmart Inc. has launched a new business unit, Upstream Facility Services, expanding its in-house maintenance capabilities to serve external companies across the United States.

The new offering leverages Walmart’s extensive operational scale and expertise developed across its network of stores and Sam’s Club locations. Upstream will provide services including HVAC, refrigeration, electrical, plumbing, and general maintenance, targeting businesses with multi-location operations where uptime and efficiency are critical.

The service model combines urgent repairs, preventive maintenance, and predictive solutions, supported by a nationwide network of technicians positioned close to customer sites. Clients will also benefit from real-time visibility into service performance, enabling improved planning and faster decision-making.

With this move, Walmart aims to commercialize one of the largest in-house facility service operations in the country, helping businesses reduce downtime, extend asset life, and improve operational consistency.
