Downspouts
3″x4″ aluminum downspouts designed to move roof runoff away from foundation areas, landscaping, walkways and entry points – the part of the gutter system that decides where the water ends up.

Where water goes
Even a well-installed gutter system can create drainage problems if downspouts are undersized, poorly placed, damaged, clogged or directing water too close to the home.


Representative examples only. Downspout routing and discharge locations vary by home.
Common problems
Downspout problems usually show up at ground level first – around the foundation, in the landscaping and on walkways.
What we install
Downspouts are planned with the rest of the gutter system. We look at how much water each gutter run carries and where it can discharge safely – then place 3″x4″ aluminum downspouts to move runoff away from the areas that matter most.
Minnesota drainage
Snowmelt sends a steady volume of water off the roof, and winter discharge can refreeze where people walk. Placement matters in every season.
Outlets sized and spaced for the steady runoff of a thaw.
Gutter size and downspout count matched to peak water volume.
Gutter guards can help keep debris out of downspouts.
Discharge moved away from walkways and doorways.

Downspouts control where water goes after it leaves the gutter. Poor downspout placement can allow water to collect near the foundation, landscaping, walkways or entry areas – even if the gutters themselves are working properly.
Yes. Downspout placement can be updated as part of a gutter repair, replacement or new installation to better direct runoff away from the home.
Common problems include downspouts that are undersized, poorly placed, damaged, clogged or directing water too close to the home. Storms, ice and debris can also crush or disconnect sections.
When downspouts release water onto walkways or entries, it can refreeze into icy patches during Minnesota winters. Better placement and discharge can help move that water where it won’t refreeze in your path.
