You can start reconstruction on your home after a flood as soon as all the moisture has been eliminated. Normally, this takes between 24 and 72 hours. This time frame can vary, though, depending on several factors such as your region’s climate and the time of year. If you purchase a moisture meter from a hardware store, it can help you determine when your house is dry.
You may need to wait for a structural engineer to assess the damage, and you also may need to wait for your local officials to issue building permits. Finally, if you’re relying on insurance money to pay for repairs, you will need to wait for that to come through.
