1. Corrective maintenance.
2. Preventative maintenance.
3. Risk-based maintenance.
4. Condition-based maintenance.
Corrective maintenance: This maintenance is often carried out after a fault or failure has been identified. For example a burst geyser or leaking roof. Most of this maintenance can be incurs a higher once off cost. This is often due the fact that the item has now failed due to lack of maintenance, often causing secondary damage, flooded floors, damaged roof etc. Large corrective maintenance costs can be offset by doing monthly inspections and maintenance.
Preventative maintenance: Carrying out preventive maintenance is creating a checklist of items that have wear over time periods that pertain to the proposed lifespan of said item. For example, tap washers been replaced yearly, geyser thermostat heat been reduced in summer months etc. Preventative maintenance could be a little more time consuming and costly, but often can prevent larger corrective repair costs.
Risk based Maintenance: This maintenance is around items that can either create harm, for example replacing that patio door from shatterproof glass to safety glass, or installing new security measures around the house such as new burglar bars or alarm system.
Cost based maintenance: the final maintenance area, is the “we can do it later maintenance.” This maintenance is more often than not, purely cosmetic. The new driveway, new pool and landscaped garden. This maintenance is often the one that adds value onto your investment, well you think it does.
