What if subfloor gets wet?

If plywood sub floors have been wet for less than 72 hours they can be saved with water extraction and the correct drying procedures (dehumidification and air movement). Once the plywood sub floor is dry it should be inspected for further damage before laying the finished flooring down over it.

In cases of extensive water damage, drying the subfloor after a flood can be very difficult, and that complicates repairs. Soaked wood quickly develops mold and rot that impacts adjacent framing and drywall. In this kind of situation, it's best to replace the entire expanse.

Furthermore, how long can subfloor be exposed? 20 to 30 years

Considering this, is plywood ruined if it gets wet?

The glue bonds weakens when the wood remains wet for a prolonged period, and the layers can eventually separate. Once plywood has become wet, you must encourage the water that has soaked into the wood fibers to evaporate to make it dry again.

How do you dry a subfloor after water leak?

If flooding occurs, and there is water leaking into the sub-flooring, it is crucial to dry out the subfloor as soon as possible. The first step is to absorb any water lurking on the surface of the floor. Then, place a dehumidifier at high settings to pull out any moisture that is still in the air.
