Your gutter system is only as good as its ability to carry water away from your home—and that’s where downspout extensions play a key role. If water tends to pool near your foundation or landscaping, it might be time to upgrade your drainage with a proper extension. In this post, we’ll explain what a downspout is, why it matters, and how to install an extension that protects your home from costly water damage.
What is a downspout?
A downspout is a vertical pipe connected to your gutter system. Its job is to carry rainwater from the gutters down to the ground and away from the base of your home. Without a functioning downspout, water would spill directly off the roof, leading to erosion, flooding, and potential structural issues.
Benefits of gutter downspouts
Adding or upgrading your downspouts—and especially using extensions—offers several important benefits:
- Protects the foundation from water pooling and seepage
- Prevents basement flooding by directing water far from your home
- Reduces soil erosion near walkways, flower beds, and patios
- Improves gutter system performance during heavy rain
- Helps preserve siding, paint, and landscaping from water damage
A simple extension can make a big difference in the long-term integrity of your property.
How to install a gutter downspout extension?
Installing a downspout extension is a manageable DIY project if you follow the proper steps and use the right tools and materials.
Step 1: Choose the right extension type
There are several types available: rigid extensions, flexible corrugated tubing, or buried drainage pipes. Choose one based on your property layout and desired water redirection.
Step 2: Measure and cut the extension
Measure how far you want the water redirected—usually 3 to 6 feet away from your foundation. Cut the extension to the appropriate length using a utility knife or saw if needed.
Step 3: Disconnect or loosen the bottom elbow
Remove or loosen the elbow at the bottom of the existing downspout to create space for the extension attachment.
Step 4: Attach the extension
Connect the extension using a coupling or adapter. For rigid extensions, screws may be required. For flexible models, you may simply slide it onto the downspout.
Step 5: Secure and angle properly
Use brackets or clips to secure the extension in place, and angle it slightly downward to allow gravity-fed drainage.
Step 6: Test for proper flow
Run water through the system using a hose to ensure the extension is directing water where it should go—well away from your home’s foundation.
