How to Clean Aluminum Downspouts

What You'll Need
Plumbers Snake
Hose Pipe

Aluminum downspouts can become clogged with loose debris and leaves and can prevent the dispersal of water from the gutters of your home.

Step 1 – Downspout

If you gutter runs into an underground tile system, you will need to remove the bottom end of the downspout. Remove the lower bracket or band that attaches the downspout to the siding of your home.

Step 2 – Removing the Blockage

If the water does not flow freely from the gutter through the downspout, use a plumbers snake attached to a drill.  Thread it up through the downspout. Push it up as far as you can until you loosen any clogged debris. It will either fall out of the bottom or get pushed up to the top guttering.

Step 3 – Rinsing

Once all the clogged debris has been removed, use a power hose and run it up inside the downspout. The water should spurt out of the top and some will run back down the spout.

Step 4 – Replacing the Parts

Once you have satisfied that the downspout is clear, replace the bracket and the bottom part of the downspout back in the draining hole. If you don’t have a draining hole your spout will just jut out at the bottom. Seal the new joint with compound if you need to.
