With forty-plus inches of annual rain, most Bellevue homes do best with 6-inch K-style gutters and oversized downspouts rather than the standard 5-inch. Larger profiles carry more water during the heavy Cascade storms that overwhelm undersized systems.

Seamless gutters remove the joints where Douglas fir needles and cedar debris usually pack in and cause clogs. Pair them with the right guard system and your gutters keep flowing through fall and winter with far less maintenance.

If your 1960s-era home has built-in or box gutters that leak, they are likely rotting the fascia and roof edge behind them. Replacing them with a modern seamless system stops the hidden water damage and is usually more cost-effective than repeated repairs.

Standard gutter replacement rarely needs a permit, but drainage tie-ins and larger projects can. We work to King County standards on slope, downspout sizing, and discharge so your system performs and stays compliant.

With proper installation, aluminum seamless gutters commonly last 20 or more years here, while copper can last several decades. The marine climate is hard on cheap fasteners, so we use corrosion-resistant hardware on every job.
