Planned preventative maintenance

See our maintenance section or contact us for more information. Guardian's repair and maintenance services and engineers are accredited to the DHF's TS004 Repairs and Maintenance standard.

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 - 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.
