Garages feel like the easiest place in a home to clean: concrete floor, a drain or driveway nearby, nothing precious. That impression is part of why garage cleanups go wrong. Unsealed concrete is porous, and garage contents are often stacked cardboard, wooden benches, rags and tools with crevices that hold fluids.
The example below is entirely hypothetical. It is meant to show the decision points, not to describe a real event.
The situation
Illustrative example. Not a real job or customer.
A homeowner in a hypothetical 1990s two-story in the south metro is badly cut while using a saw in an attached garage. A family member calls 911 and gives first aid until paramedics arrive. The injured person is taken to a hospital and recovers. Blood is on the concrete floor, a wooden workbench, a stack of cardboard storage boxes and the door into the house.
- That evening, a relative starts to hose the garage floor toward the driveway. A neighbor familiar with cleanup asks them to stop, pointing out that water spreads blood across a larger area and into the expansion joints and down the driveway.
- The family closes the garage and keeps everyone out, then calls their homeowners insurer the next morning to report the incident.
- Two providers assess the garage. One proposes a pressure wash only; the other proposes cleaning and disinfecting the slab, removing the workbench top and boxes, and treating the interior door.
- The family chooses the second plan after the provider explains that pressure washing alone can aerosolize contaminated water and does not disinfect.
- Cardboard boxes and their soaked contents are removed and listed. Tools are cleaned and disinfected and returned. The wooden bench top is replaced. The interior door is cleaned and refinished on the garage side.
- The slab is cleaned, disinfected and then sealed so remaining staining does not trap residue.
The garage is usable again, the family has a list of discarded contents for the insurer, and no one in the household handled contaminated materials without protection.

Common questions
- Does a garage injury fall under homeowners insurance?
- Possibly, depending on the policy. Report it and ask. Medical costs are a separate matter from property cleanup.
