When Deck Posts Rot — Safety Comes First | MoDecks Kirkland
Over time, even the strongest wood can fail. Moisture, poor drainage, and direct ground contact often cause hidden rot in deck posts or beams, especially in older decks built without modern waterproofing systems. What looks like a small crack can quickly turn into a structural safety issue.
At MoDecks, we specialize in identifying and rebuilding damaged deck structures the right way — from the ground up. Once wood starts to rot, patching it is never enough. Our process includes:
• Full inspection of all posts, beams, and footings
• Removal of rotted wood and installation of new pressure-treated or steel-reinforced posts
• Concrete footing rebuilds with proper elevation and drainage
• Post-base hardware and moisture barriers to prevent future decay
• Optional composite upgrade for a longer-lasting, maintenance-free deck
We also offer under-deck waterproofing and soffit systems to protect new framing from constant rain exposure — especially in the Pacific Northwest climate.
If you notice soft spots, sagging, or dark stains around deck posts — don’t wait until it collapses. A professional rebuild can restore both safety and beauty to your outdoor space.
