Spokane has a real exterior painting season, and it is shorter than most people think. The window where paint can cure properly runs from late April through mid-October in a typical year, and the practical booking season is even narrower once you account for morning dew, cold snaps, and wildfire smoke.

The conditions paint actually needs

Modern exterior paints want a stable stretch of the following:

  • Air and surface temperature above 50°F, ideally above 60°F, and staying there overnight.
  • No rain in the forecast for at least 24 hours after the final coat.
  • Humidity below 85%.
  • No direct sun on the wall being painted (we follow the shade around the house).

Below 50°F the paint film does not coalesce correctly, and you pay for it with peeling two or three years out. In our shop, if the wall is too cold to paint, we do not paint it, even if the calendar says we should.

The Spokane calendar

Late April through May

First reliable stretch of warm, dry days. Perfect for prep and first coats on south and west exposures. Morning temperatures are the main constraint, and we typically start later in the day than we do in summer.

June through August

Peak season. Long days, warm overnight lows, and we can run full schedules. The tradeoff is booking pressure. Our summer calendar usually fills by the end of March.

September and early October

Excellent conditions. The heat backs off, the light is softer, and the bugs thin out. If you missed spring booking, early fall is the strongest time to get on the schedule.

Late October and beyond

Cold snaps arrive quickly. We can sometimes finish a project into late October on a south-facing exposure, but we do not start new exterior work once overnight lows stay below 45°F.

When to reach out

For summer work, get on the schedule in February or March. For fall work, reach out by early July. Exterior painting and pressure washing share a calendar, and washing typically happens a few days before paint so the siding has time to dry.

We paint homes across Spokane, including central Spokane, Spokane Valley, Liberty Lake, Mead, Colbert, and Deer Park. Request a quote and we will give you a realistic window based on where your project lands in the season.
