Junk crews will haul from wherever things sit — preparation is optional. It is also the difference between a quick, cheap pickup and a long one, so here is the short version of doing it well.
Stage toward the driveway

Consolidate what you can move to the garage, porch, or curb; tighter staging means tighter quotes and faster loading. For what you can't move, clear the path: doors propped, halls walkable, pets managed, and box-truck space on the driveway or street.
Sort into three groups
Donate, scrap metal, junk — the sorting you do off the clock is sorting nobody bills you for. Flag fuel, propane, and refrigerant items at booking; all are handleable, all go smoother announced.
Disclose the quirks
HOA gate codes, the item heavier than it looks, the backyard route narrower than the couch — dispatchers plan around what they know and improvise expensively around what they don't. Booking photos remain the highest-value prep step in the entire trade.
Round Rock day-of notes
Summer pickups want morning slots before the heat index takes over; spring storm weeks fill schedules fast, so call early after a blow. Be reachable for the arrival window, point once, and let the crew run — most residential pickups are gone within the hour.
The recipe, condensed
Staged or reachable, sorted into three groups, quirks disclosed, phone answered — do those four and most residential pickups load and leave inside an hour, at the number quoted.
Each step is optional; each one you take is billable minutes converted into savings.
