We don't publish a flat number for off-track repair because the range is wide - a roller swap and a track realignment is a different job than replacing bent track sections or dealing with cable damage from the fall. What we can tell you is that Heathrow homes, sitting at a median household income around $122,837, well above the roughly $80,775 median across the broader service area, more often ask us to replace worn rollers with a longer-lasting steel or nylon upgrade rather than just putting the original part back in. That's a choice, not a requirement - we'll quote both and let you pick.
The honest limitation: if the track itself is bent in more than one section, or the door panel took damage in the same incident, straightening track rarely holds up long-term. At that point we'll say so and quote replacement track instead of charging you twice for a patch that won't last.
