What Are Downspout Extensions?
A downspout extension connects to the bottom of a downspout to carry roof runoff farther away from your home. It completes your gutter drainage system by directing water to a safer discharge point instead of dumping it next to your foundation.
Moving water away helps limit soil saturation and pooling that can lead to foundation problems over time.
What Happens When Downspouts Drain Too Close to Your Foundation?
When a downspout stops too close to your home, roof runoff can build up against the foundation and soak the surrounding soil. As the soil becomes saturated, hydrostatic pressure can increase, which may result in water entering through foundation cracks, window wells or the wall-floor joint.
You may notice pooling water, washed-out soil or mulch, cracked or sunken walkways, a wet basement or a musty crawl space.
Our Downspout Extension Solutions
Low-profile drainage for grassy yards
RainChute®
RainChute® is a recessed downspout extension designed for homes where the lawn begins near the foundation. Installed with its edges flush to the ground, it takes roof runoff away from the house without putting a raised extension across the lawn. Its clog-resistant design also helps move leaves and debris through the system.
Above-ground drainage for landscaped areas
RainChute EZ®
RainChute EZ® is an above-ground downspout extension that rests directly on the ground for a simple way to carry roof runoff farther from your foundation. A good fit for landscaped areas near the home, it can direct downspout water 3 to 8 feet away while letting leaves and debris flush through rather than collect inside.
How Is the Right Downspout Extension Determined?
Where Should Roof Runoff from Downspouts Go?
Downspout water should move away from the foundation to a location where it can continue flowing safely away from your home. The right discharge point depends on your property’s slope, soil and surrounding landscape.
The goal is to keep roof runoff from pooling near the foundation, washing away soil or landscaping, running back toward the house or causing drainage problems elsewhere on the property.
