Corrective maintenance

Corrective maintenance is the work that happens after something has already broken. The name is literal: you are correcting a failure that has already occurred, rather than preventing or planning for it. In a professional property management context, corrective is the residual category: the work that is left when planned maintenance has done as much as it can and a component has failed anyway. For most homeowners, corrective is not the residual but the entirety, because the planned half has never been set up.

The mechanism: corrective is the only mode that triggers itself. The boiler stops, the ceiling stains, the lock seizes; the phone rings. Planned work has no such announcement and competes with the rest of the homeowner’s week, which it usually loses. This is why corrective dominates the residential maintenance experience by default rather than by choice.

The distinction matters at three moments. Corrective is almost always more expensive per repair: time pressure narrows contractor choice, scope is whatever the failure produced (usually larger than catching it early would have been), and consequential damage is already underway by the time you call. Corrective repairs cannot be bundled, cannot wait for the right season, and cannot be scheduled into another contractor visit.

Sibling frame: the alternative to corrective is planned maintenance, which has two practices inside it: preventive maintenance (scheduled servicing that catches problems before they cause failure) and lifecycle maintenance (the longer-horizon view that pushes each component toward its full lifespan and anticipates the eventual replacement). The goal is not zero corrective work; it is reducing the share of total maintenance that arrives through the most expensive channel.
