How often do gutters actually need cleaning in Seattle?
Twice a year — minimum. Seattle's bigleaf maples drop in October. The November deluge arrives right behind them. By spring, a second round of debris, moss spores, and granule sludge has packed down into a mat dense enough to hold standing water against your fascia for weeks.
Homes under Douglas firs or near Puget Sound bluffs — Magnolia, Madison Park, West Seattle — often need a third visit in late February as alder catkins finish dropping. Here's what Seattle's rainfall actually looks like by month:
Recommended schedule for most Seattle homes:
Late October
After maple drop, before deluge
Late March
After alder catkins + winter debris
A clogged gutter is a slow water bill — paid in wood rot and concrete.
Seattle's soil doesn't drain fast. When gutters overflow, the water has nowhere to go but down — and it finds every gap in your fascia, every crack in your foundation. Here's the damage timeline we see on first-time cleanings:
Standing water
Compressed leaf mat holds moisture against the fascia board. Peeling paint begins.
Fascia rot starts
Wet wood behind the gutter bracket softens. The gutter begins pulling away from the roofline.
Foundation pooling
Overflow channels water against the foundation. Basement moisture, cracked concrete.
A gutter cleaning costs $175–$325.
Fascia board replacement: $800–$2,400. Foundation waterproofing: $5,000–$15,000.

Do you clean the downspouts too?
Yes. Everything. Here's the full scope of what happens on every visit — no upsells, no partial jobs.
Full gutter scoop & bag
Every leaf mat, granule deposit, and seed pod — hand-removed and bagged. We don't blow debris onto your landscaping.
Downspout flush
Every downspout is tested with a running hose. If it's blocked, we rod it clear before we leave.
Photo documentation
Before-and-after photos of every section. You get a text link same day — no wondering if they actually showed up.
Fascia & bracket inspection
We flag any pulling brackets, soft fascia, or early rot — in writing, with photos. You decide what to do with the information.
Moss treatment (add-on)
Zinc sulfate applied to shingle edges and gutter floors. Slows regrowth significantly through the wet season.
Yes — Seattle's steepest rooflines are our bread and butter. Capitol Hill Victorians, Ballard craftsmen, Magnolia split-levels. We carry 40-ft ladders and use standoff stabilizers. Every crew member is fall-protection certified.
Most single-family homes take 1.5–3 hours depending on linear footage and debris load. Property managers with multi-unit buildings can book a block day — we work through all units and send a single consolidated report.
We cover all of Seattle proper plus Bellevue, Kirkland, Redmond, and Mercer Island. If you're in Shoreline, Burien, or Renton — call us. We take those jobs when scheduling allows.
"Property manager for 12 Capitol Hill units. They do all of them in a single day and send one consolidated report. Exactly what I needed."
"Stopped climbing my own gutters in 2019. GutterGuard shows up every October and March like clockwork. Haven't had a clogged downspout since."
"They flagged a soft fascia board I didn't know about. Saved me from a much bigger repair. The photos made it easy to show my contractor."
