Assessing Timber Framing in Flooded Houses

What You Need to Know with Timber Framing

If you have a timber-framed house that has been affected by flooding, don’t despair! Timber-framed construction is typically resilient and can withstand moisture and extreme conditions. In many cases, the framing can be saved and reused.

However, it’s important to note that when your home is flooded, a common approach can’t be used to evaluate the damage. Each situation must be assessed on a case-by-case basis. Factors to consider include the extent of degradation and the repairs required.

To help make an accurate evaluation, you should refer to woodsolutions.com. au and their detailed Technical Design Guide No. 12 – Impact and Assessment of Moisture affected Timber-framed Construction that provides detailed information about the topic. When it’s time to clean up, don’t automatically throw away the waterlogged framing. Instead, take steps to minimize the damage as quickly as possible.

One issue to keep in mind is that mould can start growing very fast, often within 24 hours. While it doesn’t typically damage the structural integrity of the timber, it can pose a health hazard. Therefore, it’s crucial to act quickly to prevent mould growth and minimise damage.

To facilitate drying, open up the walls or other closed cavities so that air can circulate. This often means removing damaged plasterboard and insulation that cannot be salvaged. Timber takes longer to dry than it does to saturate, but you can speed up the process by using fans if possible. Additionally, mould cannot survive in a dry atmosphere.

You can use a simple moisture meter to determine whether the timber is dry enough to be reused. Generally, timber with a moisture content below 20% and free of mould can be reused. It’s common to find high Moisture readings in bottom plates directly in contact with a slab or a particle board floor.

The speed at which the timber dries can depend on several factors, including the wood density, how long it was submerged, how soon it was exposed to air, and local weather conditions. Once it has dried, it can be difficult to determine whether it’s salvageable, so it’s best to seek advice from an experienced professional.

In summary, if your timber-framed house has been affected by flooding, don’t panic. Timber-framed construction is typically resilient, and the framing can often be saved and reused. Take steps to minimise the damage and prevent mould growth as soon as possible. Consider seeking advice from an experienced professional to determine whether the timber is salvageable. By following these steps, you can restore your home and prevent further damage.
