Ranked, honestly
1. Late spring (late April – May). The best single visit of the year. You clear five months of inversion particulate, road grit, and snowmelt splash, plus the spring pollen that lands on top of it. And you head into the brightest half of the year with clear glass.
2. Early fall (September – October). Second best. Gets you clean before the holidays, before the weather turns, and it bundles naturally with gutters and Christmas lights.
3. Summer (June – August). Perfectly fine. Peak sprinkler season means spotting comes back faster, but if you're hosting or you just want it done, there's no reason not to.
4. Winter (November – March). Works on above-freezing days and it's an underrated time for interiors. More on winter cleaning.
Why late spring specifically, and not March
This is the most common timing mistake we see. People get the first warm week in March, feel the spring-cleaning urge, and book.
Then the trees let loose in April and the windows look untouched.
Wait for the pollen surge to mostly finish. Late April to May is the sweet spot in most of Davis County — a few weeks later if you're up on the bench, where things run cooler and later.
Wasatch Front factors that aren't obvious elsewhere
Inversion. The valley traps particulate for weeks at a time in winter. It settles on glass and it's finer than ordinary dust, so it forms an even haze rather than visible specks — which is exactly why people stop noticing it.
Snowmelt splash. Grit and road salt splash up onto ground-floor windows all winter.
Irrigation season. Roughly April through October, and it's the main driver of mineral spotting here.
Wind events. Canyon winds move a lot of dust in spring and fall. A big wind event can undo a cleaning, which is genuinely annoying and worth just accepting rather than chasing.
Intense summer sun. Bakes deposits on faster than a milder climate would.
Building a schedule that works
Two visits a year: late spring and early fall. That's the standard, and it covers most homes well.
Four visits: add mid-summer and mid-winter. Worth it if you have sprinkler exposure, a dusty location, or a lot of glass — and our quarterly plan makes each visit cheaper than one-time service.
One visit only: make it late spring, without question.
