Where water goes

Gutters collect the water. Downspouts decide where it lands.

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.

Common problems

Signs your downspouts aren’t doing their job

Downspout problems usually show up at ground level first – around the foundation, in the landscaping and on walkways.

  • Water pooling at the foundationRunoff collecting where the downspout meets the ground.
  • Erosion in landscapingWashed-out mulch or soil below an outlet.
  • Icy walkways in winterDischarge refreezing on paths and entries.
  • Crushed or disconnected sectionsWater released at the wall instead of away from it.
  • Clogged downspoutsGutters overflowing even though they look clear.
  • Too few outletsLong gutter runs draining to a single downspout.

What we install

3"x4" aluminum downspouts, placed with intent

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.

  • Foundation areas and basement walls
  • Landscaping and garden beds
  • Walkways, patios and driveways
  • Front entries and doorways

Minnesota drainage

Downspouts work hardest in spring and winter

Snowmelt sends a steady volume of water off the roof, and winter discharge can refreeze where people walk. Placement matters in every season.

Spring snowmelt

Outlets sized and spaced for the steady runoff of a thaw.

Heavy rain

Gutter size and downspout count matched to peak water volume.

Leaves & debris

Gutter guards can help keep debris out of downspouts.

Ice near entries

Discharge moved away from walkways and doorways.

Johnson Exteriors installs 3″x4″ aluminum downspouts.

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.
