Foundation Protection FAQ
How far should I extend from my foundation?
Minimum 6 feet from foundation walls for optimal protection. Full 55" extension recommended. Position toward drainage areas or connect to underground systems for maximum effectiveness.
Will this fit my existing downspout?
Yes! Universal compatibility with 2x3" and 3x4" systems covers virtually all residential applications. Flexible vinyl creates secure weather-tight connection without tools or hardware.
How durable is vinyl in extreme weather?
Professional-grade UV-resistant vinyl withstands -40°F to 140°F without brittleness. Impact-resistant design survives foot traffic, debris loads, and freeze-thaw cycles. Pacific Northwest tested.
Can I bury this for invisible drainage?
Yes, burial-ready design connects to underground systems. Use proper 1/4" per foot slope with pea gravel backfill. Vinyl resists soil pressure and root intrusion for permanent installations.
How many extensions do I need?
One per downspout within 10 feet of foundation. Typical 2000 sq ft home needs 6-8 extensions. Focus on downspouts near basement windows and foundation walls first.
