A pressure washer hit your turf. Here is the damage pattern, and what recovers.

The water pressure that lifts dirt off a driveway does not know the difference between grime and infill; it blasts both, and turf infill is not bonded to anything, so it goes first. Aimed at the pile itself, the same force also hits fiber tips directly hard enough to curl, fray or split them rather than simply rinse them, and if the wand crosses a seam, the pressure can drive under the edge and pop the adhesive loose. This almost always happens the same way: someone rents a washer for the patio or driveway, treats the turf edge the same way they treat the pavers, or tries to clean the turf itself the way they would clean concrete.

Look for a stripe or a fan shape where the wand passed, with infill visibly thinner and backing showing in a lane, rather than the more even, gradual thinning of ordinary foot-traffic wear. Fiber near that lane looks frizzy, curled or split at the tip instead of merely bent; bent fiber stands back up when brushed, this does not. Run your hand along every seam within a few feet of where the washer was used and feel for a ridge or a gap that was not there before.

The stripe of missing infill is topped up and re-leveled across the affected lane, which is infill replenishment. Fraying that is minor is trimmed and blended in with grooming. Any seam that has lifted is cleaned and re-glued, a seam repair from $250, or an edge re-secured from $175 if that is all that moved. Where fiber has actually been shredded down to little left, that section is cut out and patched like any other repair. None of this requires starting the lawn over, but it also is not a job for the pressure washer again, which is exactly why our own process uses a high-volume, low-pressure rinse instead.

Keep the pressure washer strictly on hard surfaces and stop at the paver or concrete line. If a painter, a pool crew or a rental job is working on the house exterior, tell them the turf is off-limits before they start, since this damage is more often done by a hired crew that did not know than by the homeowner. For the turf itself, a hose on a gentle setting or a proper clean is what the fiber and infill can actually handle.
