Give the visit a practical checklist
Identify the door and opener if their labels are readable from the floor, then list the concerns you want assessed. A maintenance visit should leave a record of observations and work performed. Repairs to damaged hardware should be explained and authorized rather than hidden inside a generic tune-up description.
Treat a new movement problem as a fault
A door that begins leaning, catching or dropping should stay out of service. Do not continue operating it to distribute lubricant or see whether the problem improves. Professional assessment is needed before routine care can be expected to restore normal use.
Keep finish work within its own scope
If faded paint or surface damage is also a concern, identify the door material and manufacturer's care guidance. Biscayne Park's local resources include exterior-paint review information and exceptions. Confirm the relevant requirements before refinishing; maintenance of moving parts does not authorize a new exterior color.
Your questions
Is paint touch-up included in a maintenance visit?
Only if it is part of the agreed scope and appropriate to the door material. Mechanical care and finishing are different tasks.
Does maintenance establish how many years a spring has left?
No. Use and condition vary; a visit cannot turn a cycle specification into a guaranteed failure date.
