What Is a Downspout Extension?

A downspout extension is an attachment added to the bottom of your gutter’s downspout. Its job is to channel water several feet away from your home, rather than letting it pool at the base of your foundation.

We install both above-ground and underground extensions to match your property layout, landscaping, and drainage needs.

1. Drainage Evaluation

We assess your current gutter system, grading, and drainage patterns to determine where water is flowing — and where it shouldn’t be.

2. Extension Design & Placement

We design a custom downspout extension layout that directs water at least 6 to 10 feet away from the home. We consider slope, yard layout, and obstructions.

3. Installation

We install either:

• Above-ground extensions (rigid or flexible pipe)

• Underground extensions (buried drain pipe with popup emitter or daylight exit)

We ensure a smooth water flow and minimal disruption to your yard.

4. Optional Upgrades

Pair your downspout extensions with:

• Exterior Damp Proofing

• Basement Waterproofing

• Sump Pump Installation

Why Downspout Extensions Matter

Redirecting water away from your home is the first — and easiest — line of defense against:

• Basement water seepage

• Crawl space humidity

• Foundation cracking or shifting

• Soil erosion near the home

• Mold growth and musty smells

• Repeated sump pump cycling

• Water damage to landscaping or walkways

Downspout extensions are low-cost, high-impact protection that can prevent major problems.

Signs You Need Downspout Extensions

• Water pools near your foundation after rain

• Basement or crawl space leaks during heavy storms

• Mulch or soil washes out near the house

• Efflorescence (white staining) on foundation walls

• Mold or mildew odors indoors

• Overflowing gutters or stained siding
