When installing 6″ gutters, we use 3×4″ oversized downspouts as well, allowing more water and debris to flow freely through the system.
We have seen an incredible increase in our number of 6″ seamless gutter installs over the past few years. We have even encountered many straight ranch, cape, and colonial homeowners interested in the larger sized 6″ gutters.
