Downspouts
in Los Angeles.
A great gutter system is only as good as where the water ends up. We install downspouts, splash blocks, extensions, and buried drains that move water away from the foundation — not pool against it. LA homes with adobe or stucco foundations are especially vulnerable to footing damage from poorly routed downspouts. We design for the long game.

Downspout sizing matched to gutter capacity
We size each downspout to the gutter run feeding it. Undersized downspouts are the most common cause of overflow during heavy rain, and they're usually a holdover from the original install.
Splash blocks or buried drain extensions
We finish each downspout where it should end — not where it's convenient. Splash blocks for level lots, extensions for tight foundations, buried drain lines for hillside or slab homes.
Routing away from foundation lines
Every downspout outlet is angled or extended to push water at least 4 feet away from the wall. We don't leave water draining straight onto stucco or paving.
Aluminum, copper, or galvanized options
Match the gutter material or pick contrast as a design choice. Most homes get aluminum; copper for heritage and high-end homes; galvanized for commercial or industrial buildings.

Downspouts are the most often-overlooked part of a gutter system. We design before we install.

Or call us — we'll be back in 15 minutes during business hours, and an on-site walk is available on request to map drainage paths in person.
Spec downspout count and size
We calculate the count and size based on roof area and gutter capacity. Most LA homes need 4–6 downspouts at 3×4. Bigger roofs or steep pitches push the count up.
Install with secure straps
Downspouts are strapped plumb to the wall every 4–6 feet, with attention to where straps anchor — into framing where possible, into masonry with proper anchors when not.
Connect extensions or buried drains
Each downspout gets terminated correctly: splash block, surface extension, or buried drain. For buried drains, we trench, lay PVC at proper slope, and either pop up at the property edge or tie into an existing drain line.
Test under flow
We run water through every downspout and watch where it ends up. If anything pools or backs up, we adjust before we leave.
What actually drives the price.
- Number of downspouts. Most homes get 4–6. More on larger roofs, fewer on smaller bungalows. Each downspout adds material and labor.
- Length and routing complexity. Long runs around bay windows, second-story drops, or tight architectural details add labor. A straight drop from gutter to splash block is the cheapest case.
- Material. Aluminum is the LA default. Copper runs 3–5×. Galvanized is between but mostly used commercially.
- Buried drain runs (trenching). Trenching for buried drain lines is a separate cost driver — figure linear feet of trench plus PVC, fittings, and a pop-up or street tie-in.
- Accessibility. Tight side yards, sloped lots, or routing through landscaping add labor.
