If you notice pooling water around your gutters, you may need to redirect water flow in the downspouts. Downspouts are an important part of the gutter system, as they drain water from the exterior. 

A downspout keeps the water from flooding the foundation or freezing water from forming in the driveways from runoff. In most cases, all it needs is an extension. Adding a downspout extension is something you can do yourself by following these tips.

Prepare to Work

For this project, you need:

  • work gloves
  • safety glasses
  • step-ladder
  • marker
  • garden hose
  • rags
  • needle-nose pliers
  • screwdriver
  •  sewer stand pipe
  • support brackets
  • metal hacksaw
  • drill galvanized screws
  • downspout elbow extension

Set a step-ladder on flat ground where you can easily access the downspouts. Use a  rag to clean out the downspout ends. Spray a stream of water up the downspout with a hose, and let it dry.


Draw a map your gutter system that includes the turns and the path you want. Figure how many straight sections you have and how many elbows you need. Determine the angle and size. Standard elbow angles are seventy-five degrees, though they come in thirty to ninety degree sizes. Water should drain at least twenty feet from the foundation.

Insert a standpipe where the downspout meets the connection, and mark nine feet on the downspout. Trim the downspout at this mark with the hacksaw. Plug the standpipe with a cap to prevent debris form entering it.

Install the Elbows

Connect the elbow  an inch into the funnel-shaped part of the gutter. Fasten the elbow to the gutter using  a screwdriver to attach screws. Insert two more screws on the sides of the gutter.

Grip the round portion of the elbow with pliers, and bend it three-fourths of an inch. Crimp the whole edge in the manner to help it stay secure on the downspout. To make installation easier, pre-drill holes in the elbows.

Secure a drop outlet running from the start downspout to the end of the gutter to redirect water to the downspout. Mount the downspout to the outlet with support brackets and screws. Add a nut to the end of the screw to secure.

Insert the elbow into the bottom of the downspout as far a possible; pointing the opening away from the house. The elbow should be placed on the inside. Secure it with screws. 

Attach the second elbow to the second downspout  at a ninety-degree angle; ensuring it runs parallel to the driveway. Insert the third elbow and remaining elbows in the same manner. Add a drop outlet to the last elbow.
