The short answer
A typical two-story house wash takes 2–4 hours; a two-car driveway 45–90 minutes; a roof treatment 1–3 hours; a full house-plus-concrete-plus-gutters package most of a day. Much of a soft wash is solution dwell time, not spraying. Surfaces are walkable within hours; true dry is by the next morning.
Real Durations, Not Brochure Ones
| Job | Typical time on site | What stretches it |
|---|---|---|
| House wash (two-story) | 2–4 hours | Heavy growth, stucco/cedar detail, tight access |
| House wash (ranch) | 1.5–2.5 hours | Same factors, one fewer story |
| Two-car driveway | 45–90 minutes | Stain treatment, aprons and walks added |
| Roof soft wash | 1–3 hours | Pitch, complexity, established lichen |
| Gutter cleaning | 1–2 hours | Footage, debris load, downspout clogs |
| Deck or patio | 1–2 hours | Wood needing brightener as a second step |
| Whole-exterior package | Most of a day | The bundle discount's honest cost: one longer visit |
Why the Crew Sometimes Looks Like It's Not Working
A soft wash is chemistry with a rinse at each end. After application, the solution needs dwell time — several minutes of sitting on the surface killing what lives there. A crew standing by while the house "does nothing" is the job working; rushing that stage is exactly the corner the splash-and-dash operators cut, and it is why their results return in months. On heavy growth, a second application doubles a wall's dwell and is time well spent.
Speed sorts contractors backwards. A whole two-story house "washed" in 45 minutes was rinsed, not treated. If two quotes differ mainly in how fast they promise to leave, the slower one is usually the one doing the job.
When Can You Use Everything Again?
- Walkways and driveway: walkable as soon as the crew is off them; fully dry look returns in 1–4 hours of decent weather
- Siding: drips stop quickly; the house reads fully dry by evening
- Pets and kids on lawns/surfaces: once dry — same day
- Cars back on the driveway: same day for cleaning only; 48–72 hours if the drive was sealed
- Painting after a prep wash: 24–72 hours depending on surface — the schedule in our pre-paint guide
How Weather Moves the Day
Light drizzle changes nothing — the house is getting wet on purpose. Storms and lightning stop work; sustained wind complicates two-story solution control; and cold below about 40°F ends the season rather than the day. Crews watch radar and will call an audible on sequencing (concrete in the morning dry window, siding after) rather than cancel outright when the day is mixed.
Scheduling the Visit
Most washes are a morning or an afternoon, booked as a window rather than a minute. You do not need to be present — ten minutes of prep and gate access cover it — and bundled packages are deliberately scheduled with slack so nothing gets rushed to make a second appointment. One crew, one setup, one cleanup is also exactly why the bundle prices better than three separate visits.
The Bottom Line
Plan on hours, not days: 2–4 for the house, about one for the driveway, most of a day for the full package — with dwell time doing invisible work in the middle and everything dry by the next morning. The duration to be suspicious of is the one that sounds impressively short.
