Downspouts that drain right next to the foundation are one of the most common contributors to foundation water problems. We connect homeowners with contractors who install underground drainage pipe that carries roof runoff well away from the house and outlets it safely — a simple upgrade that significantly reduces foundation water load.

Why Short Extensions Don't Work

A splash block moves water two feet from the house. During a heavy rain, that water saturates the soil against the foundation before it can drain away. Over time, that repeated saturation leads to water intrusion in basements and crawl spaces. An underground downspout drain carries the water completely away from the structure.

How Underground Downspout Drainage Gets Installed

A solid PVC pipe gets connected to the downspout base, buried below grade with adequate slope, and routed to a daylight outlet at the edge of the property. The outlet is placed where the discharged water won't create a new drainage problem. The system is low-maintenance and handles the full volume of roof runoff during heavy rain events.

Frequently Asked Questions

Should downspout water be routed into a french drain?

Generally no — downspout runoff is best handled with its own solid, non-perforated pipe to an outlet. Tying it into a french drain can overload the drain faster than it's designed to handle.

Will fixing my downspouts reduce how much french drain I need?

It can. Getting roof runoff away from the foundation on its own pipe reduces the water load a french drain would otherwise have to manage, so we look at downspouts as part of the overall system design.

Why isn't a splash block enough to protect my foundation?

It only moves water a foot or two, which isn't far enough — the soil right against the foundation still gets saturated. That saturation is often what eventually calls for a foundation-perimeter french drain.

How is underground downspout pipe different from a french drain?

A french drain has perforations and gravel so it can collect water from the surrounding soil. Downspout pipe is solid, since its only job is to carry roof water to an outlet without picking up anything else along the way.
