What Materials Are Most Damaged by Water?

Drywall and plaster are extremely vulnerable because they soak up water like a sponge. Once wet, these wall materials quickly lose their strength and can sag or collapse. The paper facing on drywall is a prime food source for mold. Insulation inside walls also holds moisture, reducing its effectiveness and hiding damage from view.

Wood is another highly absorbent material. Subflooring, framing, and hardwood floors swell when wet, causing boards to cup, buckle, or warp. The moisture breaks down the wood's fibers, leading to rot and compromising the structure's safety. This damage often happens out of sight, so a professional inspection is crucial to assess the full extent of the problem.

Books, documents, photographs, and important papers are often destroyed by water. The ink runs, pages stick together, and mold can develop within a day or two. While some items can be freeze-dried by specialists, the process is time-sensitive and not always successful. It is best to prioritize moving these items to a dry area immediately.

Cardboard boxes holding stored items will disintegrate quickly. The moisture wicks into the contents, damaging clothing, memorabilia, and other belongings. Storing precious items in plastic bins instead of cardboard can provide an extra layer of protection against humidity and unexpected leaks.

The longer materials stay wet, the worse the damage becomes. Mold can begin growing on damp drywall or wood within 24 to 48 hours. Swift water extraction and drying are the only ways to prevent total loss of absorbent materials. Delaying action often leads to more extensive repairs and higher costs.

Professional drying involves industrial equipment to remove moisture from the air and materials. This process seeks to stabilize the environment to prevent additional damage. Even when you act quickly, some materials may be too damaged to save. An accurate assessment determines what must be removed and what can be dried in place.
