Steel vs. Pressure-Treated Wood: The Ultimate Showdown for Pacific Northwest Decks
When you’re building a deck in the Pacific Northwest, you’re not just creating a place to relax — you’re going to war with moisture, rot, and long, wet winters. That’s why the frame you choose matters more than any other part of your deck.
At Modernized Exteriors, we specialize in building luxury decks across the Seattle area that are built to last — and we’re here to break down the real difference between traditional pressure-treated wood framing and modern steel framing.
🌧️ Why the Pacific Northwest Punishes Wood
Let’s be honest: Seattle doesn’t mess around with weather. From constant rain to high humidity, pressure-treated lumber is constantly at risk of:
Rot and decay
Insect damage
Warping, splitting, and sagging
Costly replacements every 7–10 years
And when that wood is hidden beneath your deck, it’s easy to miss issues until they become expensive problems.
