Why Downspouts Matter

Downspouts are what carry the water from your gutters down to the ground and away from the house. They are an essential part of any gutter system — without them, water would spill straight down and destroy your lawn, landscaping, and foundation.

In many homes the downspout feeds into an underground drainage system that sends all the water to one place, or a system that redirects it well away from the house. Done right, it keeps your basement dry and your yard intact.

5-Inch vs. 6-Inch Downspouts

Downspouts come in two main sizes — 5-inch and 6-inch — in a range of colors to match your home. For most homes, 6-inch is the better choice: they are wider, so water flows down more easily and the chance of clogging is much lower than with a 5-inch downspout.

If your gutters keep overflowing, undersized downspouts are often part of the problem. Pairing larger downspouts with the right gutter size handles far more water — see our gutter repair page for more on sizing up.

Downspout FAQs

What does a downspout do?
The downspout carries water from your gutters down to the ground and away from your home. Without it, all that roof water would dump next to your foundation and tear up your lawn and landscaping. Many downspouts feed into an underground drainage system that moves the water to one safe outlet.
Should I get 5-inch or 6-inch downspouts?
Bigger is usually better. 6-inch downspouts are wider, so water flows through them more easily and they clog far less often than 5-inch. If your roof is large or steep, or your gutters overflow, we will usually recommend sizing up.
What colors do downspouts come in?
We offer downspouts in a wide range of colors to match your gutters and trim, so the drainage blends into your home rather than standing out.
Can you connect my downspouts to underground drainage?
Yes. We can tie your downspouts into an underground drainage system that carries water away to a single outlet — ideal for keeping water off your foundation and out of low spots in the yard.
Do you repair downspouts or only install new ones?
Both. We repair loose, leaking, or damaged downspouts and elbows, and we install complete new downspout runs — fabricated on-site to fit your home.
