Is Dry Rot covered by household insurance?
No… dry rot occurs overtime, and is considered a maintenance issue, which insurance doesn’t cover. In the eyes of the company you should have kept up with your home and repaired things overtime. Even though dry rot is sometimes hidden it’s still up to the owner to know if there house is up in age, than some things need repair/replacement regardless if the appear broken. Insurance is for things that are sudden/accidental/unexpected. Not long term taking care of your house things like replacing siding.
