Where should gutter downspouts be placed?

You'll likely want your downspouts to run down the side or back of your house. Downspouts come in a variety of colors so they can match your siding and won't be so noticeable if they end up closer to the front of the house. 5. Downspouts should extend 4-6 feet away from your home.

How far should your downspouts be extended from house?

The gutters must be clean to prevent clogging. The downspouts need to be extended away from the home a minimum of four feet, with six feet being preferred. When downspouts are connected to underground drains, it is very important to keep all debris out of the gutters, downspouts and underground drains.
