When rainwater management fails, foundations crack, basements flood, and landscaping washes away. A properly sized downspout is a small component with massive consequences—especially in the storm-prone Midwest. But what is the real cost to install downspout on a residential property today? CountBricks analyzed hundreds of recent projects and combined those numbers with our live materials database to give homeowners and contractors the clearest picture available.
Material choice, house height, and labor complexity create wide swings in pricing. Vinyl downspouts might seem economical, but aluminum and copper last longer and can add curb appeal. Two-story installations require additional safety gear and time. Finally, seamless systems demand onsite forming equipment and skilled labor that impact the bottom line.
• Vinyl, 2x3 in., one-story: $10-$14 per linear foot installed
• Aluminum, 3x4 in., one-story: $13-$17 per linear foot installed
• Aluminum, 3x4 in., two-story: $16-$22 per linear foot installed
• Copper, 3x4 in., decorative elbows: $29-$40 per linear foot installed
Note: Rates include fasteners, straps, elbows, and labor based on CountBricks.com/services regional cost feed. Permits or haul-off fees are additional.
On a typical 1,800-sq-ft home needing 60 linear feet of downspout, material costs range:
• Basic vinyl: $240-$300
• Standard aluminum: $330-$420
• Premium copper: $900-$1,200
Labor in St. Louis averages $2.10 to $3.25 per linear foot for single-story homes and climbs to $4.50 on tall façades. CountBricks crews optimize time by pre-crimping offsets in our shop, reducing onsite hours by nearly 20 % compared with traditional methods.
• Ladder stabilizers and roof jacks: $45 daily rental
• Seamless roll-forming trailer (if required): $1.25 per linear foot amortized
• Disposal of existing downspout: $75 average per haul
• Splash block or drain-tile connection: $25-$75 per location
• Soil grading at discharge point: $2-$3 per sq ft
Traditional paper takeoffs rely on rough sketches and outdated price books. CountBricks replaces guesswork with three proven technologies:
• AI blueprint takeoffs: Upload a PDF and receive quantified downspout lengths, elbow counts, and hardware in minutes.
• Realtime voice capture: Walk the job with our mobile app, call out material choices, and see costs update instantly.
• Dynamic price library: Our system pings regional suppliers every morning, so your quote reflects today’s aluminum coil price, not last quarter’s.
Paint touch-ups: Matching existing trim can add $100-$200.
Foundation tie-ins: Directing water into an existing French drain may require excavation or new PVC adapters.
Historic district approvals: Decorative copper or galvanized steel might be mandated, pushing costs higher and slowing timelines. CountBricks handles submittals so you avoid fines.
The average flooded basement remediation in St. Louis sits around $9,800. Upgrading undersized 2x3-in. downspouts to 3x4-in. models for $900-$1,300 is inexpensive insurance. Realtors within CountBricks’ partner network report a 2 % resale value boost when gutter systems look fresh and function flawlessly.
