Laundry pickup and delivery in the District.
Washington is compact enough that a single answer for the whole District sounds reasonable, and that is precisely why it would mislead you. Hampr availability is assembled locally, so it fills in block by block and not by ward or quadrant. The check below is scoped to one address on purpose, and it is the only thing on this page that can tell you anything binding.
One address at a time is the only honest way to answer this.
The laundry problem here is mostly a housing problem: shared basement machines, card readers, a laundromat that costs you a Saturday. Handing the bag off takes the errand out of the week rather than moving it.
Wherever the check comes back positive, the routine is the same: a bag left out, collected by a washr, washed and folded to your preferences. Pricing and turnaround appear in the app for your order.
The DC page below exists because people were already searching for it, not because the District is uniformly covered. Run your own address, and if the answer is not yet, you can leave an email instead of guessing.

Each of these has its own page and its own address check. Being listed here does not mean the whole place is served.
