Gutter Installation and Repair in Seattle
Seamless gutter installation, repair, and gutter guard systems for Seattle homes. Protect your foundation from water damage with K Single Corp.
Seattle Seamless Gutter Installation Since 2007
K Single Corp has installed and repaired seamless gutter systems across King, Snohomish, and Pierce counties since 2007, completing more than 15,000 exterior projects with a 4.7-star Google rating. Properly sized gutters are not optional in a region that absorbs 37 plus inches of rain a year. Undersized or sectional gutters overflow during PNW storms, rotting fascia, soaking siding, and undermining foundations within a single wet season.
Our crews fabricate seamless 5-inch and 6-inch K-style gutters on site from continuous aluminum coil, with copper upgrades available for premium and historic homes. Every system is engineered with correct pitch, hidden hangers, oversized 2x3 or 3x4 downspouts, micro-mesh gutter guards where trees demand them, and integrated fascia and drip edge work so the entire roof edge sheds water cleanly away from your foundation.

K Single Corp installs, repairs, and maintains seamless gutter systems designed for the Pacific Northwest’s heavy rainfall, protecting your home’s foundation, fascia, and siding from water damage.

Seattle averages over 150 rainy days per year, making gutters one of the most critical systems on your home. Without properly functioning gutters, rainwater cascades off your roof and pools around your foundation, causing erosion, basement moisture, fascia rot, and siding failure. We see the results of failed gutter systems regularly, and the repair costs are always higher than what a new gutter installation would have cost.

Built for Pacific Northwest Conditions
Gutters in Seattle's Climate
37+ inches of annual rain, 150+ overcast days, salt-air drift off Puget Sound, freeze-thaw at higher elevations. Every gutters project we deliver is spec'd for what Seattle actually throws at it.
High Rainfall Sizing
Seattle averages 37 plus inches of rain across 150 plus wet days a year. We size 5-inch or 6-inch gutters and 2x3 or 3x4 downspouts to your actual roof area so the system never overflows during atmospheric river events.
PNW Tree Debris
Douglas fir needles, cedar fronds, and big leaf maple leaves clog standard gutters fast. We pair micro-mesh guards with appropriate hanger spacing to handle the heaviest PNW organic debris loads.
Eastside Ice and Freeze
Issaquah, Sammamish, and higher Bellevue elevations see freezing rain and brief ice dams. Properly pitched, fully supported gutters with heated downspout options prevent ice buildup and seam failure.
Foundation Drainage
Water dumped at the foundation is the leading cause of basement moisture and crawl space rot in Seattle. We route downspouts with extensions or underground tightlines to discharge well clear of the structure.
