Clogged downspout cleaning and repair in Antelope, CA

A new or replacement downspout in Antelope runs $50–$150, and extensions run $25–$100 each. When we install new seamless gutters ($17–$25 per foot), the downspouts are included.

Away from the foundation. Antelope has engineered subdivision drainage with underground systems requiring properly functioning downspout connections, flat pad grades relying entirely on gutters to move water away from foundations, so we carry water 4 to 10 feet from the house with an extension, or tie the downspout into a splash block, pop-up emitter or solid drain line where the yard allows.

One at each corner of a run and at least one every 35 to 40 feet of gutter. Long runs, big roof sections that drain into one gutter, and valleys that dump a lot of water often need an extra downspout or a larger 3x4-inch one.

Yes. We run solid pipe from the downspout to a pop-up emitter or another outlet downhill from the house. Solid pipe matters: perforated pipe lets the water out next to the foundation, which defeats the purpose.

The downspout is clogged, the extension is too short, or the ground slopes back toward the house. Antelope gutters collect maturing ash and sycamore street trees now producing significant seasonal debris that builder-grade gutters were not sized to handle, combined with HOA standards requiring tidy gutter appearance, and that debris tends to settle in the elbows, so we flush and water-test every downspout we work on.
