Your decking material affects daily comfort and long-term maintenance in Idaho’s 100° summers and snowy winters. One standout: Armadillo composite—fade- and moisture-resistant, cap-protected—no sanding, staining, or sealing required.

Planning To Build a DIY Deck?

Keep these in mind:

Stairs, Concrete, Framing & More

These details make your deck feel like home—and they all affect budget:
