Why the three sources disagree
The spread here is unusually wide. HomeGuide prices a single downspout swap at $30 to $75, Angi puts a typical job at $670 ($6.50 to $22.25 per foot), and Fixr averages $1,527 at $15 to $28 per foot.1,2,3 Our reading: HomeGuide is pricing a simple one-off replacement of a basic aluminum or vinyl drop, while Angi and Fixr are pricing professional whole-home installations where materials, multi-story labor and prep all stack up. Which benchmark fits depends on the scope of your job, so we show all three.

Labor, repair and maintenance
Angi says labor is 20% to 50% of a pro job and prep adds 2% to 20%.2 For repairs, HomeGuide quotes $3 to $5 per foot for sectional fixes and $6 to $17 per foot for seamless, with handymen at $50 to $80 per hour; Fixr puts handyperson labor at $37 to $68 per hour.1,3 Gutter and downspout cleaning runs $120 to $235 per visit (Angi), or $100 to $250 (HomeGuide).1,2 Replacing gutters and downspouts together costs $2,200 to $5,000 or $12 to $25 per foot (HomeGuide).1
DIY or hire
Angi estimates DIY saves up to 50% but flags ladder safety on taller homes.2 A single-story vinyl or aluminum swap is one of the more approachable exterior DIY jobs (our view); two-story work and seamless fabrication belong to pros. Home Depot’s downspout section carries sections, elbows and extensions (plain link, not affiliate).
