Late May and early November are the two windows that matter for most US homes. Cleaning two weeks too early means doing it again. Cleaning two weeks too late means a contractor who is fully booked. The right week, with enough lead time to act on it.
Done in seconds. No sign-up required.
For a standard twice-a-year cadence, plan around two windows: late spring after the last debris of the season has fallen, and late fall after the bulk of leaf drop is done. The exact week depends on your region and your trees, but the principle is the same — clean after each debris season ends, not during it.
After the last frost, after seed pods and pollen drop. Catches winter grit, dead branches, and spring debris in one pass. Less time-pressure than fall — you can shift a week without major consequences.
After 80–90% of leaves have fallen, before the first hard freeze. This is the critical cleaning — winter consequences (ice dams, frozen debris, snowmelt backup) are far worse than summer consequences.
Climate moves the windows by two to three weeks. Here is the rough timing for the major US regions. If you live in a transitional area, average the two nearest rows.
| Region | Spring window | Fall window | Notes |
|---|---|---|---|
| Northeast (NY, MA, CT, NJ) | Mid-May to late May | Late October to mid-November | Fall is critical — first hard freeze often hits by Thanksgiving. |
| Midwest (OH, MI, IL, MN) | Late May to early June | Late October to early November | Earlier fall window than the Northeast — leaves drop fast. |
| Mid-Atlantic (PA, MD, VA, DC) | Mid-May to early June | Mid-November to early December | Later leaf drop than further north — wait for the oaks. |
| Southeast (NC, SC, GA, FL panhandle) | Late April to mid-May | Mid-November to early December | Year-round oak shedding — consider a third cleaning in late summer. |
| Deep South (FL, AL, MS, LA) | Late March to mid-April | Late November to mid-December | Hurricane season adds post-storm cleanings June–October. |
| Southwest (TX, AZ, NM, NV) | Late March to mid-April | Late November to mid-December | Less debris overall — once a year may be enough if no trees nearby. |
| Mountain West (CO, UT, ID, WY) | Late May to mid-June | Mid-October to early November | Snowpack lingers — wait for it to fully melt before spring cleaning. |
| Pacific Northwest (WA, OR) | Late April to mid-May (after rain stops) | Mid-October to early November (before rain returns) | Time around the wet season, not the calendar. |
| California (Coastal & Central) | Late April to mid-May | Late November to mid-December | Wildfire ash adds an unscheduled cleaning after major fire events. |
Spring mistakes are recoverable. Clean two weeks too early and you do it again — annoying, but cheap. Fall mistakes are not. Clean two weeks too early and the next leaf drop refills the gutter before winter, which is worse than not cleaning at all because you have used up your contractor budget and your motivation.
Wait two weeks too long and the first hard freeze arrives. Frozen debris cannot be cleaned until it thaws, which in northern regions means February or March. By then you have had two months of ice damming, snowmelt backing up under shingles, and the kind of damage that spring cleaning cannot reverse.
The fix is to set a reminder that fires with two to three weeks of lead time so you can watch the leaf drop and pick the right week. A reminder that fires "do gutters today" is usually too late. One that fires "schedule gutters in the next 2–3 weeks" gives you useful flexibility.
October is the peak month for gutter service demand in most US markets. Local contractors get booked out two to three weeks ahead, and the best ones often hit four. If you wait until you see leaves piling up, the choice narrows to whoever has an opening, not whoever does the best work.
For fall, contact your contractor by early October. For spring, two weeks ahead is usually enough — May is a much quieter month for gutter services. If you have an established relationship with a contractor, ask them to put you on a recurring schedule; many will slot regulars first when bookings open.
For more on how often to schedule based on your specific situation, see how often to clean your gutters. For the cost of getting the timing wrong, see what happens if you don't clean your gutters.
Clean on a dry day after at least two days without rain — wet leaves are heavy and cling to the gutter, slowing the work. Cool days are easier than hot ones because debris is less likely to be infested with stinging insects. Avoid windy days for obvious ladder reasons.
For a two-story home, plan on ninety minutes total: thirty minutes setting up the ladder and protecting the area below, forty-five minutes of actual scooping and bagging, and fifteen minutes flushing the downspout with a hose. Block out a half day on your calendar, not a half hour.
Late spring (mid-May to early June) and late fall (late October to mid-November) are the two main windows for most US homes. Spring catches winter grit and seed pods; fall catches the bulk of leaf drop. Aim to finish each cleaning within a two-week window, not stretched out across a whole month.
Wait until 80–90% of the leaves have fallen, then clean within two weeks. In most of the country that lands between late October and mid-November. Cleaning too early in fall means doing it twice; waiting too long risks the first hard freeze locking debris in until spring.
After the last frost and after the seed-and-pollen drop has finished — usually mid-May to early June in most regions. Cleaning in March or April often misses the spring debris that falls in May. The exception is if your fall cleaning was skipped: in that case, clean as soon as the snow melts, then again in late May.
Fall is more critical because the consequences of skipping (ice dams, frozen debris, winter overflow) are worse than spring consequences. If you can only do one cleaning a year, do it in late fall. But "one cleaning" is risky for most homes — twice a year is the safer baseline.
May and November are the most universally appropriate months for a twice-a-year schedule. Heavy-tree homes should add a June and an October cleaning. Pine/evergreen homes spread cleanings to roughly April, July, October, and January. Adjust by region — see the regional table on this page.
For fall cleaning, book by early October. The peak demand window is October 15 to November 30 in most markets, and the better local contractors get booked out two to three weeks ahead. Spring is less competitive — booking two weeks ahead is usually enough.
Set a free email reminder for the start of each gutter cleaning window. Two to three weeks of lead time means you book a contractor instead of begging one.
