Common Questions
Downspout Services Questions, Answered
How many downspouts does my Houston home need?
Rule of thumb: one downspout per 20–30 linear feet of gutter. A typical Houston home needs 6–10 downspouts. Larger or more complex rooflines need more — we calculate per-roof during the on-site estimate.
Should I run downspouts underground?
Often yes. Houston's expansive clay soils want water moved 6+ feet from the foundation. Underground PVC drains carry that water out to the curb or yard daylight — cleaner look and far better foundation protection than above-grade extensions.
How much do underground downspout drains cost?
Underground drain installation in Houston typically runs $300–$800 per downspout depending on trench length, soil, and discharge point. Cheaper than the $5,000–$30,000 average for foundation repair caused by poor drainage.
Can downspouts connect to rain barrels?
Yes. We install diverters that send water into a rain barrel and bypass back to the main downspout once full. Useful for garden irrigation and reduces stormwater runoff.
Why are my downspouts overflowing during heavy rain?
Three common causes in Houston: (1) downspouts are undersized for the catchment area, (2) clogs from leaves or shingle grit, (3) the splash block or extension at the bottom is back-flooding. We diagnose during a free site visit.
