Maintenance vs. Repair: What's the Difference?

Edited by Aimie Carlson || By Janet White || Updated on November 11, 2023
Maintenance involves regular upkeep to prevent problems, while repair is fixing something that is already broken or damaged.

Key Differences

Maintenance typically refers to the routine actions taken to keep equipment or systems functioning efficiently and prevent breakdowns. In contrast, repair is the process of fixing or restoring something that has already malfunctioned or been damaged.
The goal of maintenance is to prolong the life of an item or system and ensure its efficient operation, often through regular check-ups and servicing. Repair, however, is usually a reactive measure taken to correct defects or damages that have already occurred.
Maintenance can be scheduled and planned, involving activities like cleaning, lubrication, and adjustments. On the other hand, repair is often unscheduled and performed in response to a specific issue or failure.
While maintenance is about preserving the current state of an item, repair is about restoring it to its previous condition after a fault or damage.
Maintenance is a proactive approach focused on prevention, whereas repair is a reactive approach focused on correction.
