A dented slat rides differently in the guide. First it catches; then it drags the slats either side out of line; then the curtain stops rolling square onto the drum.
If your door catches at the same point every cycle, that is the warning. Stop using it. The difference between acting then and acting in a month is often the difference between a guide adjustment and a $1,200 curtain.
Salt collects where the curtain meets the slab, and water sits there after winter rain. So the bottom two or three slats always go first.
On a canal block at Port Mandurah or Wannanup, that's salt from the estuary as well as the ocean. Rinsing the bottom of the door with fresh water occasionally is unglamorous and it genuinely works.
A single damaged slat can sometimes be swapped on a curtain that's otherwise sound and still a current profile. Realistically that's the minority of cases.
Once several slats are involved, or corrosion has run along the width, the curtain goes as a unit — $700 to $1,900 depending on the opening width and the material.

Where this job typically sits. Access is usually a bigger cost driver than size.
| Job | Indicative price | What moves it |
|---|---|---|
| Service call and diagnosis | $90 – $180 | Attending and identifying the fault. Most operators credit it against the repair — ask, because not all do. |
| Roller door spring re-tension | $150 – $320 | Restoring tension to a drum spring that no longer holds the curtain up. The most common single job in this region. |
| Roller door curtain replacement | $700 – $1,900 | Replacing a dented or corroded curtain. Width and material drive the number. |
| Torsion spring replacement | $250 – $600 | Sectional door springs, replaced in pairs where the door has two. |
| Cable replacement | $150 – $350 | Usually done alongside springs, because they wear together. |
| Motor / opener repair | $150 – $450 | Boards, capacitors and gear sets on an opener still supported by parts. |
| New opener supplied and fitted | $450 – $1,200 | Depends on door weight and whether you want app control or a keypad. |
| Off-track correction | $150 – $400 | Re-seating the door and replacing whatever let go. More if a panel or slat is bent. |
| Full service | $120 – $250 | Tension, cables, rollers, tracks, opener limits and safety reverse. |
| Door replacement, existing opening | from $1,400 | Roller doors sit at the lower end here; wide insulated sectionals at the upper. |
Prices are indicative only. What a job costs depends on the door type, the width of the opening, the part, and whether it can be repaired or has to be replaced. You get a firm price before any work starts.
