Modesto Downspout Services — Your Local Neighborhood Team

Most Modesto downspout blockages form at the first elbow below the gutter outlet — the sharp bend where debris compacts under gravity. A second common blockage point is underground transitions where downspouts connect to drain pipes with smaller diameter. Modesto's almond blossoms, agricultural dust, and storm debris creates the conditions for these blockages to form repeatedly during the rainy season.

Most Modesto homes fall in the $50–$150 per downspout. Cleaning and unclogging runs $50–$100 per downspout. Repair or section replacement is $75–$150 per downspout. New downspout installation, rerouting, or underground extension work is $100–$200 per location. We assess and quote before any work begins.

Modesto's Tuolumne River floodplains, canal networks, and clay soils near dairies means soil saturation near foundations creates real damage risk — slab cracking, wood rot, persistent efflorescence. Discharge within three feet of a foundation often causes these problems within a few rainy seasons. Extensions cost $25–$100 and route water at least six feet out, eliminating the problem before it starts.

Yes. Many newer Modesto developments connect downspouts to underground drain systems leading to street drains or sump pits. We install new extensions, repair damaged underground sections, and inspect existing systems for root intrusion or silt accumulation that's blocking flow.
