We see the damage from bad gutters on every other house in Portola Valley: rotted fascia, stained siding, eroded foundation soil, and water pooling around the base of the home. Good gutters aren't optional. They're the first line of defense for everything below your roofline.
We install 5-inch and 6-inch seamless K-style gutters. Standard homes get 5-inch. Larger roof areas, steeper pitches, or high-volume drainage zones get 6-inch with oversized 3x4-inch downspouts. Sizing matters. Undersized gutters overflow, undersized downspouts back up.
Our Gutter Installation Process
Gutter Assessment
Our estimator measures your roofline, calculates drainage capacity requirements, and checks fascia condition. We determine the right gutter size, downspout count, and placement before quoting anything.
Custom Forming
We bring our portable gutter machine to your Portola Valley property and form continuous seamless pieces to the exact length of each run. No factory seams, no joints. One piece of aluminum per section.
Expert Install
Gutters installed with correct pitch, secure hangers, sealed end caps, and properly sized downspouts. If your existing fascia is soft or damaged, we replace it before hanging the new gutters. No point putting new gutters on rotten wood.
Water Test & Walkthrough
We test the new gutter system with a water flow check before we leave. Every connection, every downspout, every end cap, confirmed watertight. Old material removed and the area cleaned up.
