What Are Downspout Extensions, Exactly?
A downspout extension attaches to the bottom of a downspout to carry roof runoff farther away from your home. It completes your gutter drainage system by sending water to a safer discharge point instead of releasing it next to your foundation.
Getting water away from the house helps reduce soil saturation and pooling that can contribute to foundation problems over time.
What Happens If Downspouts Drain Too Close to the Foundation?
When a downspout ends too close to your home, roof runoff can collect against the foundation and soak the surrounding soil. As the soil becomes saturated, hydrostatic pressure can increase, which may contribute to water entering through foundation cracks, window wells or the wall-floor joint.
You may notice puddling water, washed-out soil or mulch, cracked or settled 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 made for homes where the lawn starts near the foundation. Installed with its edges flush to the ground, it moves 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 landscaping near the home
RainChute EZ®
RainChute EZ® is an above-ground downspout extension that rests directly on the ground for a simple way to move roof runoff farther from your foundation. Ideal for landscaped areas near the home, it can direct downspout water 3 to 8 feet away while allowing leaves and debris to pass through instead of building up inside.
What Determines the Right Downspout Extension?
Where Should Downspout Water Go?
Downspout water should drain away from your foundation to a location where it can keep draining safely away from your home. The right discharge point depends on your property’s slope, soil and surrounding landscape.
The goal is to stop roof runoff from pooling near the foundation, washing away soil or landscaping, flowing back toward the house or producing drainage problems elsewhere on the property.
