Downspouts channel water from your roof and gutters into the ground following a specific route so water doesn’t accumulate around your house’s foundation. Without a downspout, the standing water will wash away material and disrupt the soil, leading to foundation erosion. The standing water will also form ice around your house during cold weather, causing a safety hazard.

Yes, there are several downsides to installing rain chains. For one, rain chains have a lower flow capacity than a typical gutter and downspout system. This means that if there is a rainstorm, the rain chain can stop working completely. Rain chains also cannot redirect rainwater away from your house. In homes with a sloped yard, this could cause water damage in your foundation or basement. 

If you don't want to install gutter guards, the most common and inexpensive alternative is regular gutter cleaning, either annually, biannually, or as soon as they start to fill up. Using a leaf blower attachment can make this process easier. Other products designed to reduce cleanings include gutter screens (made of wire mesh, nylon, or foam), which are typically less expensive than a full gutter guard installation. You can also find guards and inserts designed specifically to protect your downspouts or opt for a whole gutter system like LeafGuard, which integrates the gutter and guard into a single product.

Gutter cleaning costs about $170 on average, ranging from about $75 to $400. Cost factors include the type, length, and height of your gutters. A multiple-story home with gutters high off the ground and accessible only by ladder or working on a steep roof will cost more than a single-story house with a relatively flat roof.
