Mountain West Climate & Decking Challenges
The Mountain West — Utah, Nevada, New Mexico, Idaho, Montana, and Wyoming — shares Colorado's high-altitude challenges across a vast region. Low humidity (often below 20%), intense UV amplified by elevation, aggressive freeze-thaw cycling, and heavy snow loads at elevation create conditions similar to Colorado but spread across diverse landscapes from desert valleys to alpine peaks.
The core challenge is the same: extreme dryness combined with extreme temperature swings. Wood that can't handle low humidity checks and splits. Wood that can't handle freeze-thaw cracks and fails. Tropical hardwoods, with density that minimizes moisture-related movement, handle Mountain West conditions with the stability these environments demand.

Ipe Decking in Mountain West
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 Mountain West
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.
Mountain West 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 Mountain West
Oil 1x/year in spring. Mountain UV is intense but single application suffices. End-sealer is more critical than oil in this region.
