After the Rain: What to Do With Water-Damaged Items

The remnants of Tropical Storm Marie dropped the first measurable rain Los Angeles had seen in months this week, with some areas topping 1.5 inches and high surf causing coastal flooding in Seal Beach. Rain like that is rare enough in September that a lot of garages and storage areas were not set up for it — here is what to do with anything that ended up wet.

Why “just let it dry” is not always the right call

Cardboard, particleboard furniture, and anything with fabric or foam can start growing mold within 24 to 48 hours of getting wet, especially in a closed garage with limited airflow. If a box or piece of furniture is still damp two days later, drying it out is no longer the goal — it is already past the point where mold is a real possibility, not just a risk.

What usually does not survive

• Cardboard boxes and their contents. Once cardboard has been wet, it loses structural strength permanently, even after it dries — it will not protect what is inside it in the future.
• Particleboard or MDF furniture. Unlike solid wood, particleboard swells and delaminates when it gets wet and does not go back to its original shape.
• Rugs and carpet padding left on a garage floor. These hold moisture against the floor long after the surface feels dry.
• Anything already on its way out. A water event is often what finally decides the fate of stuff that was already marginal — old paperwork, out-of-season clothes in cardboard, holiday decorations in non-sealed bins.

What is usually fine

Solid wood furniture, metal shelving, and anything in sealed plastic totes typically comes through a wet garage without lasting damage — wipe it down and let it air out fully before putting anything back.

Getting it out before it becomes a bigger problem

Wet cardboard and damaged furniture get heavier and messier the longer they sit, and mold risk only goes up with time. If a storm left a pile of stuff that is not coming back from it, that is a same-day call, not a someday project — we can usually get to a property the same day and clear the whole pile in one trip.
