How Long Term Leak Can Devastate Your Subfloor Plywood

Damaged subflooring due to long term water damage

Water leaks in a home are more than just an inconvenience; they can lead to significant structural damage over time, especially when the problem goes undetected or unresolved for an extended period. One of the most vulnerable areas in your home to long-term water exposure is the subfloor, particularly if it’s made of plywood. Subfloor plywood is a structural component that sits beneath your finished flooring, providing a stable base for materials like hardwood, tile, or carpet. It plays a critical role in maintaining the integrity and stability of your floors. However, as sturdy as it might be, plywood is particularly susceptible to damage when exposed to moisture over long periods. Plywood that remains wet for extended periods is prone to rot. Fungal growth can set in, breaking down the wood fibers and causing the plywood to decay. Once rot takes hold, it can spread quickly, further deteriorating the subfloor and potentially spreading to adjacent structural elements. Rot not only weakens the subfloor but can also lead to unpleasant odors and even health hazards due to mold growth. Where there’s moisture, mold and mildew are likely to follow. Mold can grow both on the surface and within the layers of the plywood, making it difficult to completely eradicate. Mold not only damages the subfloor but also poses serious health risks.
