Maximizing Rainwater Management: The Advantage of Underground Downspout Extensions in Chicago NW Suburbs!

Updated: Mar 29

Is Extending Downspouts the Key to Preventing Water Damage to Your Home?

Extending the downspouts and discharge line under the ground allows you to keep water away from your house structure, reducing the risk of water damage, seepage, and leaks. Your house downspouts and basement sump pump discharge pipe are the primary sources of directing water toward the foundation wall during rain and snowmelt. Therefore, a reliable yard drainage system is necessary to keep your basement dry and minimize the chances of standing water next to your home or closer to the foundation.

How can extending your downspouts underground help protect your home from water damage?

Installing an underground sump pump discharge and underground downspout extensions is a great way to redirect water away from your home's foundation walls and prevent water-related issues. If your current downspout and basement sump pump discharge system is not efficient enough, adding underground extensions will increase the distance the water travels. This will significantly reduce the risk of water seepage, leaks, water damage, and standing water near your house or foundation. By doing so, you can protect your home from water-related hazards.


Maximizing the Efficiency of Downspouts: How Far Should Underground Downspout Extensions Extend from Your Home?

Home G Group Inc. recommends that the underground drainage extension end at least 10 feet from your foundation wall to avoid water damage. If your lawn naturally slopes, use the slope to enhance drainage and redirect water away from your home. However, the effectiveness of this approach depends on the grading of your land and yard.


Where Should I Direct My Downspouts and Sump Pump Discharge Line?

The Underground extensions can end in a pop-up emitter in a low area in your yard or be connected to the city storm sewer system.
