Seattle Public Utilities tells homeowners to clean their gutters at least twice a year, and in this climate the fall cleaning does the most work. November is Seattle's wettest month, and it arrives just as the leaves come down. Angi's Seattle guide puts a professional cleaning at about $157 to $311, with an average of $218, against about $119 to $234 nationally. Here is when to schedule it, what the different jobs cost, and how to tell whether your gutters need a cleaning, a repair or replacing.
When to clean gutters in Seattle
The local rule of thumb comes from the city's own utility. Seattle Public Utilities' wet weather guide says to inspect gutters "regularly for leaks or damage" and to "clean at least twice a year." It doesn't name the months, so here is how we'd read it against the local weather.
NOAA's climate normals for Sea-Tac put about 39 inches of rain in a normal year. Nearly half of it, about 45%, falls from November through January: 6.31 inches in November, 5.72 in December and 5.78 in January. In each of those months, rain of a tenth of an inch or more falls on about 12 or 13 days.
That rain lands on a season's worth of leaves. SPU's October 2026 notice calls this "drainy season" and puts it plainly: "Windy, rainy weather is here and so are our fall leaves."
Clean once after most of your leaves are down. That cleaning handles the heaviest load, ahead of or during the wettest stretch. There's no hard cutoff. If it's already December and your gutters are full, they're still worth clearing.
Clean again in spring. That clears what the winter left behind, and it's a good time to look over the system for leaks and damage.
Go more often under big trees. Bob Vila's cost guide gives a more cautious general rule of "at least three times per year or at the change of each season," while allowing that milder climates may need only two. If your roof sits under large trees, twice a year may not be enough, and your own gutters will tell you. Check them during a hard rain.
Signs your gutters need attention
You can learn a lot from the ground during a steady rain, with no ladder involved. Walk around the house and look for:
These matter because the water has to go somewhere. Bob Vila's guide describes overflow getting into "any crack in the roofline, down the walls, and along the foundation," and says standing water "weakens the upper walls and the fascia." In Seattle, wood that stays wet through a long rainy season is where rot starts, and exterior repairs to fascia and trim are a bigger job than a cleaning.
What gutter work costs
Angi publishes Seattle figures for cleaning and new gutters. We didn't find a Seattle figure for repairs, so that row is national. These come from consumer cost guides rather than a survey like Cost vs. Value, and their sample and method aren't always published, so use them for rough scale. A real number depends on your house.
The national figures are at Angi and Fixr. Treat the new gutter rows with care, because sources disagree widely. Fixr's range sits well above Angi's Seattle range, and Bob Vila's installation guide, updated in 2023, lists $622 to $1,677 nationally. Length, height and material explain a lot of that gap.
Seattle's average cleaning runs about 30% above the national one, which fits the local labor market. The Bureau of Labor Statistics reports a mean wage of $42.11 an hour for construction and extraction workers in the Seattle area in May 2025, against $31.42 nationally. That's a broad category rather than a gutter-specific rate, but labor is much of what you're buying on a cleaning.
A few things move a price within those ranges:
- Height. Angi's Seattle guide lists $157 to $200 for one story, $188 to $275 for two and $234 to $311 for three.
- How much is in there. A gutter that's been left for a few years takes longer than one cleaned last spring, and some companies charge extra for each clogged downspout.
- Material, for new gutters. Fixr's per-foot figures run $5 to $10 for vinyl, $7 to $13 for aluminum and $18 to $32 for copper.
- Construction, for new gutters. Continuous gutters formed in long runs have fewer joints than sectional ones. Bob Vila lists labor at $2 to $6 a foot for sectional and $3 to $10 for continuous.
Cleaning, repair or new gutters
Most gutter problems point to one of the three jobs. This is our plain-language read of how to sort them.
A cleaning is probably enough when the gutters are straight, the joints are tight and the overflow lines up with visible debris. Run some water through after a cleaning to check. If it reaches the downspout and comes out the bottom, you're done.
A repair makes sense when the problem is local: one leaky seam, a section that has pulled loose, or a clogged or crushed downspout. Bob Vila's repair guide notes that caulking a seam is "not a permanent fix," though it can "get another season or two out of the gutters." Loose gutters often need better fasteners. And gutters need a slight pitch toward the downspout, so a section that holds standing water after the rain stops may need rehanging rather than cleaning.
New gutters are worth pricing when leaks and loose sections keep coming back, rust has spread, or the fascia behind them has to be replaced anyway. As Bob Vila puts it: "If you're spending too many afternoons repairing your gutters, it might be time to replace them." Fixr says well-kept aluminum gutters can last 20 years, so the age of your system is useful information too.
If water has been getting behind the gutters for a while, the damage may have gone further, so ask for a look at the siding repair and trim underneath while the work is being scoped. Water stains and peeling paint below a gutter are also worth dealing with before the next exterior paint job, since new paint won't stop water that keeps coming.
What about gutter guards?
Guards can reduce how often you clean, but they don't end the job. Bob Vila's guide says they "may decrease the need for frequent gutter cleaning" and lists installation at $6 to $8 a foot. Under heavy tree cover, ask how the product handles your kind of debris and how you'd service it, and compare that cost to a few years of regular cleanings.
Where the water goes after the gutter
A clean gutter only helps if the downspout gets the water away from the house. SPU's guidance is specific: direct downspout flows "at least 5 feet away from your foundation, without sending flows to adjacent properties." It adds: "Never discharge water over the edge of a steep hill." That last one matters on Seattle's slopes, where a well-meant splash block can send water where it does real damage.
If you're not sure where your downspouts drain, watch them in a rain. Splash blocks and extensions are simple fixes. Sending water somewhere new is a different question. SPU says to coordinate with the city's permitting department on "approved points to discharge water," and outside Seattle, your own city's rules apply.
Leaves on the ground are part of the same problem. SPU says "leaves clog storm drains and can cause flooding on rainy days." Raked yard leaves go in yard waste, but leaves from a storm drain go in the garbage. SPU food and yard waste customers can also set out up to 10 extra bags of leaves on each November collection day for no additional charge, in paper or certified compostable bags.
Permits
Routine gutter work rarely raises a permit question, though Seattle's Do You Need a Permit page doesn't mention gutters by name. It lists "painting or cleaning a building" among projects that usually don't need a permit, and says "you don't need a permit for minor repairs or alterations that cost $6,000 or less in any 6-month period." SDCI's list doesn't apply in an environmentally critical area, which includes many steep slopes, and you need a permit for any work on load-bearing supports or changes to the building envelope, no matter how small the project. Outside Seattle, check with your city.
Do it yourself, or hire it out
On a one-story house with level ground and a straightforward roofline, cleaning your own gutters is a reasonable weekend job. Two stories, a steep slope, a wet or mossy roof or wet ground is where we'd stop and hire it out. Bob Vila's guide is direct about this: "Ladder accidents are a common source of emergency room trips."
If you do it yourself, the basics come from workplace ladder guidance that applies just as well at home:
The ladder points come from OSHA's portable ladder card and the construction safety alert linked above. Staying off the roof and keeping the ladder off the gutter are our own advice. If you're hiring it out, Washington's Department of Labor and Industries suggests comparing at least three written estimates and using its contractor lookup to check registration, bond and insurance. Our post on checking a contractor's registration walks through it. Pacific West's registration number is PACIFWC905PQ.
If you manage a property
The same guidance applies, with more paperwork. Note when each building was last cleaned and what was found, so you can spot the sections that keep clogging. For an association or a rental, check who is responsible for the gutters before you schedule anything, and tell the contractor how many stories the building has, how they'll reach the gutters, and whether residents need notice.
