Wildfires can cause serious damage to your home. The building and many of the things in your home may have been badly damaged by flames, heat, smoke and water. You may find things that the fire did not burn up but are now ruined by smoke and soggy with water used to put out the flames. Anything you want to save or reuse will need to be carefully cleaned. The firefighters may have cut holes in the walls of the building to look for hidden flames. They may have cut holes in the roof to let out the heat and smoke. Cleanup will take time and patience.
If your home was exposed to wildfire smoke and ash, you want to make sure it and its contents get properly inspected, tested, cleaned, treated and restored to pre-exposure condition. Damage to your home and possessions by smoke and ash may be covered in your insurance policy. Contact your insurance company before you begin cleanup to learn more about your coverage and how to file a claim.
