Gutter Styles in Sunnyvale & the Peninsula

K-style has a flat back and a front shaped like crown molding, and it is what most homes carry because it handles large amounts of water and the shape adds strength. Half-round is an open, rounded trough that reads as more traditional and decorative. Both come in 5 and 6 inch and in every material we install.

A clean K-style in a color matched to the fascia usually keeps an Eichler or mid-century ranch roofline crisp and quiet. Craftsman and older traditional homes often suit half-round, and copper half-round is a classic accent on period houses. A Solutionist matches the profile to the architecture, from Sunnyvale ranches to modern builds.

Yes. Both K-style and half-round can be formed as radius gutters that follow a curved section of the house, like a semicircular bay or entry. Radius work is the most difficult type of gutter installation and is not offered by most gutter companies. For angled bay windows, bay miters turn the 45 degree corners cleanly.

A 2 by 3 inch downspout is the standard with 5 inch gutters, and a 3 by 4 inch downspout usually goes with 6 inch gutters because the bigger trough takes on more water. Round downspouts come in 3 and 4 inch, corrugated or smooth, with smooth round offered in copper only. Round and rectangular carry water about equally.

Screw-in hidden hangers. The Quick Screw hidden hanger is the strongest option, with a pre-started screw driven at an angle through the back of the gutter into the fascia. Many older Peninsula homes still have nail and ferrule hangers, and those nails work loose as the wood expands and contracts, which is why so many old runs sag.

Every corner miter is sealed in three places: the manufacturer’s seam in the middle, the inside where the gutters overlap into it, and the top where the runs meet. On a seamless system the corners are where the joints are, so that triple seal is what keeps a winter downpour inside the gutter.
