DIY Gutters and Downspouts: Everything You Need to Know

At BlueBarrel, we specialize in DIY rainwater catchment systems. Gutters and downspouts are an essential part of the drainage system on any home. They are also necessary for efficient collection of rainwater.

In the rainwater harvesting world, gutters and downspouts together are known as the “conduit system,” along with the downspout diverter that takes the plentiful roof runoff into rain barrels or tanks.

For those who like to tackle their own home projects, this article combines a variety of resources for DIY gutter installation, repair, and maintenance.

Gutters vs. downspouts: It's common to mix these terms, but it's important to know which element you're talking about when planning a rain barrel system.
