Idaho Climate & Decking Challenges
Idaho's dry mountain air, intense UV, and heavy snow loads demand dense hardwoods. Proper acclimation and end-sealing ensure long-term stability in this extreme environment.

Ipe Decking in Idaho
Ipe is the premium Mountain West choice — same altitude performance as Colorado across the entire region. Its 3,684 Janka minimizes checking in dry air, handles freeze-thaw without structural issues, and resists altitude-amplified UV.
Installation Adjustments for Idaho
Acclimation
14-21 days minimum — same extended protocol as Colorado. Dry mountain air requires patient acclimation.
Board Spacing
1/4" to 5/16" gaps — wider than standard to account for seasonal expansion.
Fasteners
304 stainless acceptable throughout the Mountain West
Best Installation Timing
Best: June-September. Mountain towns: July-August is the ideal window.
Special Considerations
End-seal EVERY cut immediately — the #1 maintenance rule for Mountain West. Extended acclimation at elevation. Wider spacing than standard.
Idaho Maintenance Calendar
Spring
Critical: full cleaning after winter. Inspect for checking. Oil application. Re-seal any exposed end grain.
Summer
Enjoy. Spot-clean as needed.
Fall
Final cleaning before winter. Clear debris.
Winter
Clear snow with plastic shovels. Avoid chemical de-icers on deck surface.
Oiling Frequency for Idaho
Oil 1x/year in spring. Mountain UV is intense but single application suffices. End-sealer is more critical than oil in this region.
Hardwood vs. Alternatives in Idaho
| Feature | Ipe Hardwood | Cedar | Trex Composite | Redwood |
