Non-comprehensive maintenance contracts:
The "minimal" contract which only includes the maintenance acts of the professional (regular visits and intervention in case of breakdown) as well as the minimum of spare parts. Most of the spare parts to be changed are therefore to be paid by the customer, in addition to his contract.
Comprehensive maintenance contracts:
The "extended" contract which includes the maintenance operations of the professional (regular visits and interventions in case of breakdown), the replacement of the most commonly used spare parts which are damaged or defective in the framework of the maintenance mission. The extended contract is more widespread than the minimum contract.
At WeMaintain, we strongly recommend that you opt for an extended contract. This avoids the time lag between issuing the estimate, signing it, ordering the parts and replacing the part in question.
