Downspout Extensions for Better Yard Drainage

Direct Roof Runoff Away from Your Foundation—Where It Belongs

If your downspouts dump water right at the base of your home, they could be doing more harm than good. Uncontrolled runoff can saturate your soil, damage your foundation, and lead to basement seepage or landscape erosion. At Diversified Drainage, we install professionally routed downspout extensions that carry water away from your home—whether that means 5 feet or 50. We'll design a solution that fits your yard, protects your foundation, and keeps your landscaping intact.

About the Service: Why Downspout Extensions Matter

Roof runoff is one of the biggest sources of excess water around your home—and it all flows through your gutters and downspouts. Without a proper extension, water can quickly overwhelm your foundation or nearby low spots.

We install:
  • Above-Ground Extensions
    Discreet, durable piping that carries water across the surface to a safe discharge zone.
  • Buried Downspout Extensions
    Subsurface pipe systems that move water underground to a dry well, French drain, or drainage outlet—hidden and effective.
  • Pop-Up Emitters
    Low-profile, spring-loaded caps that release water at grade only when needed, ideal for lawns and landscapes.
  • Drainage System Integration
    Tie downspouts directly into French drains, dry wells, or storm drainage systems for total water control.
  • Custom Routing & Grading
    We’ll find the safest discharge point on your property and ensure proper slope—so water flows naturally and away.

Why Downspout Extensions Are So Important

Protect Your Foundation - Water pooling at the base of your home can lead to cracks, leaks, and long-term structural damage.
Prevent Basement Water Intrusion - Proper extensions reduce the volume of water pressing against basement walls and slabs.
Eliminate Erosion & Soggy Landscaping - Stop water from carving ruts, washing away mulch, or drowning plants near your home.
Reduce Ice Buildup in Winter - Avoid icy patches near walkways or driveways where water discharges and refreezes.
Improve Overall Drainage System Performance - Downspouts work best when they’re part of a well-planned water management system.

Residential Drainage FAQs

Proper residential drainage starts with the right system—and a clear understanding of how it works. Explore these FAQs to learn more about drainage.

How far should a downspout extend from my house?

At least 5–10 feet, but more if the slope is flat or your soil drains poorly. We design based on your specific yard conditions.

What’s the best type of extension: above-ground or buried?

It depends. Buried systems are more discreet and permanent; above-ground systems are easier to inspect and adjust. We install both.

Is this something I can DIY?

Basic above-ground extensions can be DIY’d, but proper slope, discharge placement, and long-term reliability are best handled professionally.

Can I tie my downspouts into my French drain or sump system?

Yes—and it’s often the best way to manage all runoff together. We’ll design a system that integrates properly.
