VISUAL APPEAL

BUDGET PICK

Garapa Decking in Naperville, IL

Garapa can handle moderate Midwest conditions (southern OH, IN, MO) but the extreme cold of northern Midwest states pushes this lighter species hard. For IL, MI, MN, WI, we recommend Ipe, Cumaru, or Massaranduba for the best freeze-thaw performance.

Installation Adjustments for Naperville, IL

Acclimation

10-14 days. Midwest humidity varies wildly by season — acclimate to the AVERAGE conditions, not the extremes.

Board Spacing

3/16" to 1/4" gaps. Account for seasonal wood movement — boards will be narrowest in dry winter and widest in humid summer.

Fasteners

304 stainless acceptable throughout the Midwest (no coastal exposure)

Best Installation Timing

Best: May-September. Avoid freezing conditions. June-August offers the best combination of warmth and workable humidity.

Special Considerations

End-seal all cuts. Midwest humidity swings mean boards cycle through expansion/contraction seasonally — proper spacing prevents buckling. PT substructure rated for ground contact in heavy-frost zones.

Naperville, IL Maintenance Calendar

Spring

Critical season: full cleaning after winter salt, sand, and debris. Inspect for frost heave on posts. Oil application after cleaning.

Summer

Enjoy. Spot-clean as needed. Best time for any repairs.

Fall

Final cleaning before winter. Clear debris from between boards and drainage paths.

Winter

Clear snow with plastic shovels. Avoid chemical de-icers on deck (sand for traction). Hardwood handles heavy snow loads well.

Oiling Frequency for Naperville, IL

Oil 1x/year in late spring after cleaning. Midwest UV is moderate — one application maintains color well through summer.
