Hi MrSanders,


Thank you for your question and welcome to our community.


It sounds like you have a water leak that has not been repaired.  This is the common cause of dry rot.  There are a number of ways that the water can enter the interior walls.  Be sure to check the seal around your windows as well as any drainage area on your roof.  



If the dry rot is coming from the bottom, you may have an issue with the wood being in contact with the ground or moisture entering into an unsealed area due to a sprinkler, drainage or other moisture source.  When this happens, moisture can be wicked up from the ground into the stucco or wood and create your type of situation. 


Does your outside stucco or wood fascia come into contact with the ground?  If you are able to remove the soil from this area, you will be able to avoid the moisture from the ground.   Some of the older houses with stucco do not have a weep screed/sill screed installed at the base of the stucco wall.  The weep screed allows for drainage of the stucco during wet conditions.


 You will need to trouble shoot the cause of your moisture problem before you make any new repairs.  Otherwise, you will have a repeat of this same problem later on.  Some of the most common causes are seal failure at the flashing around the windows or along the roofline.


It is important to get rid of this type of a leak due to the mold and mildew which can be a result of the moisture leaking into the interior of your walls.


Please let us know if you have any further questions.
