Along the Wasatch Front, "whenever windows look dirty" isn't really a schedule — by the time you notice, the buildup has usually been baking on for weeks. Each season along the Front hits glass differently, so the right time to book depends on what month it is as much as what your windows look like right now.
Spring: book early, before the rush
Spring is when the most people call at once — the same pollen that dusts every driveway also films every window, so by the time it's obviously dirty, everyone else has noticed too. Getting on the schedule in March or early April, before sprinklers turn on, means your cleaning happens on your timeline instead of whatever slot is left once the season gets busy.
Summer: plan around sprinkler season instead of fighting it
Sprinklers and irrigation water run from roughly May through October, and any window they reach is going to need attention no matter when you book. Instead of waiting for spotting to show up, plan a booking for a stretch when your system runs lightest, or line up a mid-summer visit ahead of time if it runs daily — the earlier a booking lands relative to when the overspray started, the less mineral buildup there is to remove.
Fall: a narrow window that's worth booking early
The ideal fall appointment lands after most leaves are down but before the first real storm — and that stretch can close in a matter of days depending on the year. Waiting for the "perfect" week to call often means missing it entirely, since everyone else is trying to book the same narrow window. It also pairs naturally with gutter cleaning, so one call can cover both before the holidays.
Winter inversion: the easiest appointment to get on the calendar
Utah's winter inversions settle a gray haze over the valley for days or weeks at a time, coating south- and west-facing glass with a dull film that most homeowners blame on "winter light" rather than dirty windows. Because so few people think to book in January or February, it's typically the one time of year you can get a fast turnaround instead of waiting the week or two that spring and fall bookings usually require.
The best time to book each service
- Gutters: book as soon as most of the leaves are down and before the first hard freeze — that window shifts every year, so don't wait for a fixed date
- Exterior windows: book for after sprinkler season starts winding down, so a fresh cleaning doesn't get re-spotted right away
- The late-winter inversion clean: book it while the calendar is wide open — it's the easiest appointment of the year to schedule on short notice
- Multiple services: if you're already booking one visit, add the others to it instead of scheduling separate trips
