general maintenance
Electric roller doors (insulated)
The door curtain is made from aluminium slats that roll up into a box above the opening
These are usually sold as 'maintenance free'...but they do need some checks from time to time
Check curtain is clean, particularly in the joints between slats
Check tracks are clean and dry
Check motor limit settings ie upper and lower stop points are correct
Check links or straps between curtain and shaft are not loose or cracked (the back box cover if fitted will need to be removed for this)
Check fur strips in channels are present and secure
Check endlocks or webbing strips are not damaged (these stop the slats sliding sideways)
Check safety system is functioning correctly
Change safety system batteries if fitted (some systems have a 'curly wire' and therefore no batteries)
Sectional doors:
The door is made from four or five sections and travels vertically up a track and back into the roof of the garage
These doors do require regular maintenance and sometimes some adjustment
Check all fixings are tight
Apply oil to roller shafts, pulleys and spring
Keep channels clean and dry
Disconnect from motor and check door balance
Up and over doors
Oil all moving parts
Keep channels clean and dry
If it's a motorised door, disconnect and check door balance
Check for wear and tear
STEEL ROLLER DOORS
These are very low maintenance
Keep the surface of the door clean
Keep channels clean and dry
If motorised, check the balance of the door with the motor disconnected
SIDE HINGED DOORS
Just make sure the hinges are oiled/greased
If you hardly use the fixed leaf open it every now and then to prevent hinges from seizing
