The door has started grinding, rattling or banging on the way up
Why it happens
Most garage door noise comes back to dry rollers, hardware that has worked loose, or a spring that needs adjusting.
Why it matters
Noise is the cheap warning. Deadlock's own published line is that a small adjustment now costs far less than a snapped spring or a burnt-out motor later.
Response
All three causes sit inside the standard service, which covers lubrication, tightening, and spring tension and balance, so a noisy door is usually a service booking rather than a repair.
