Missoula Deck & Patio: Climate, Market & Cost Drivers
In Missoula's persistently wet climate, pressure-treated wood decks require diligent annual sealing and typically need replacement in 12–18 years. Composite is the practical upgrade — most quality composites carry mold, stain, and rot warranties for wet climates. Gapping between boards and clearance beneath the deck prevents moisture buildup that causes rot in framing lumber.
