Rust on springs, cables and fixings
Why it happens
Salt-laden air from the canals and river settles on steel parts every day, especially under deep eaves where rain doesn't rinse the door.
Why it matters
Garage door rust weakens parts under tension, which can snap and leave the door stuck or crooked. Signs to watch for: orange flecks on springs, frayed or stiff cables, rust at the base of the tracks.
Response
Thom treats light surface rust and replaces corroded springs, cables and fixings, then rebalances the door.
