What to Do if Your Composite Deck Board is Loose
If you’ve noticed a composite deck board that feels wobbly or moves under your feet, it’s time to take action. In Bothell’s damp Pacific Northwest climate, seasonal expansion, temperature changes, and constant moisture can cause hidden fasteners to loosen or framing to shift. While composite decking from brands like TimberTech and Trex won’t rot, the wood structure underneath still needs care and maintenance.
Our professional repair process includes:
Full frame inspection – Checking joists, beams, and blocking for movement, rot, or water damage.
Fastener upgrade – Replacing loose clips or screws with stainless steel, composite-rated hardware for a secure, lasting hold.
Extra blocking & bracing – Adding structural support to prevent further movement and keep boards tight.
Moisture protection – Applying waterproof flashing tape to joists and connection points to prevent future damage.
Leaving a loose board unfixed can create safety hazards and shorten your deck’s lifespan. At MoDecks, we specialize in composite deck repair, structural reinforcement, and full replacements. Whether it’s one loose board or an entire surface, we make your deck feel safe, solid, and beautiful again.
