Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the downspout color exactly to your gutter color for a seamless look, or use a contrasting trim color if that suits the elevation. .024 aluminum is a good thickness for residential walls where occasional impact is likely. Plan at least one downspout per roughly 30-40 ft. of gutter as a general practice, and add elbows at the top and bottom to angle water away from the foundation.
Install downspouts from a secure ladder and follow sealant and fastener safety instructions.
Order your Mastic Smooth Round 4 in. Downspout in the color that matches your gutter system.
