Maintenance contract
Merford Special Doors manufactures functional doors. It is important that the operation and the function of the door are guaranteed for the future. Regular maintenance is very important whatever the function of your door – fire resistance, sound insulation or air-tightness. This is why Merford offers customised maintenance contracts.With a maintenance contract you not only extend the service life of your doors, you also fulfil the statutory obligation of annual maintenance (according to the requirements of NEN-EN 12635). A maintenance contract provides certainty regarding the annual performance of preventive maintenance (including checks on functionality, hinges and locks, seals, etc). In this way you are fully aware of the condition of your doors at all times. Depending on their use, regular maintenance of our doors may need to be more frequent. This is the responsibility of the owner or user of the door. Your specific wishes concerning maintenance can be set out in the maintenance contract. Good (preventive) maintenance will help you avoid unexpected repair costs. Maintenance work on our special doors must be carried out by a suitably qualified person. Our installation staff are VCA** certified for installation and maintenance work.
