7ft Downspout Extension Benefits - Problems Solved
Foundation Crack Prevention
Eliminates water pooling that causes costly foundation cracks. Hydrostatic pressure from saturated soil is the #1 cause of foundation damage - our 7ft extension moves water beyond the danger zone.
Basement Flood Protection
Keeps your basement dry by redirecting 100% of roof runoff 7 feet from foundation walls. Prevents the water infiltration that leads to mold, mildew, and expensive waterproofing repairs.
Soil Erosion Control
Protects your landscaping and prevents uneven settling. Water discharged too close to the foundation washes away topsoil and can expose foundation footings over time.
Save Thousands in Repairs
A single 7ft extension costs under $50 vs. $5,000-$15,000 for foundation repairs. The most cost-effective insurance against water damage you can buy.
Slope Grade Compensation
Properties sloping toward the house need extra length to overcome gravity. Our 7ft extension handles up to 5% grade - standard extensions fail at just 2% slopes.
Zero-Tool Installation
Installs in under 5 minutes with no tools required. Simple slip-fit connection over your existing 2x3 downspout outlet. Optional screws available for permanent installation.
ā ļø WARNING: Short Extensions Put Your Home at Risk
Standard 2-4ft extensions are NOT enough for many properties. Foundation experts recommend 6-10 feet of water redirection for properties with challenging grades, clay soils, or existing moisture issues. Water pooling within 5 feet of your foundation is the #1 cause of basement flooding and foundation cracks - problems that cost $5,000-$15,000+ to repair. Don't gamble with your home's foundation.
