Repairs are restoration work for when an asset breaks, gets damaged, or stops working. Maintenance refers to routine activities and/or corrective or preventive repair done on assets to prevent damage and prolong the life expectancy.

Essentially, maintenance is what you get regularly done on your vehicle to make sure it stays in fighting form. Maintenance is something that's scheduled – like an oil change – whereas service is when you need something specific fixed or tuned up that's outside of your regular maintenance schedule.

‍Common repair and maintenance expenses include costs incurred for: Replacing broken or worn-out parts with comparable parts. Repairing HVAC units, toilets, and faucets. Cleaning building structures and systems.

Repairs are classified into four classes based on the level of damage - superficial, general, principal, and major. Depending on the class of damage, different repair methods like cement mortar bonding, shotcreting, or jacketing are required.
