Why have your door and shutter systems maintained?
- It is a legal requirement - as failure to show evidence of maintenance could mean prohibition & enforcement notices being served and fines up to £5000 and imprisonment for 2 years. 'Safety In Use', the New European CEN Standards legislation - States that all types of door should be maintained in an efficient state, in efficient working order and in good repair. For further clarification visit www.dhfonline.org.uk.
- Routine maintenance prolongs the operational life of the installation and ensures that the installation is kept in good working order.
- It ensures that the door is working in a safe and efficient condition - helping to prevent accidents and damage which in turn results in down time, effecting work flow, productivity and resulting in loss of revenue.
- It assists in identifying potential problems which can easily be rectified.
