   stan... sounds like  a lot of moisture migrating from the ground up thru the brick wall...

   try temporarily covering the brick with polysheet and see what happens..

    you can alos take  a humidity reading with a sling psychrometer

   The thing that's certain is that there is moisture in the room air. Where from is uncertain in my mind. It could be the bricks wicking but might be from side or above too, or somehow getting into room from inside house. I'm interested what is the access from house and how used..

   Thank you for your theories.  I might add that this is a 90+ year old house without insulation in the brick walls.  This porch begins approximately 16 ft above ground.  The mortar is in good shape, the foundation is comprised of 18" thick stone walls, and the ground area beneath the porch is a screened in concrete patio.  I wouldn't think that there is excessive moisture in the ground around the foundation in this area.  The access to the sunporch is a french door in one of the bedrooms upstairs.  The roof over the sunporch is tar and gravel and does not leak.  The ceiling in the sunroom is dry.  I hope that this clarifies the conditions surrounding this area.

   Thanks,

   Stan

   stan..... the ground under the stone foundation doesn't have to be excessively wet..

   the bricks act as an almost perfect wick... try the poly taped to the porch brick wall  and see if you have condensation on the back of it.... dollars to donuts , that's the source of your moistureMike Smith   Rhode Island : Design / Build / Repair / Restore

   I like the brick wall hypothesis, however I propose that it is coming from above the porch. Check for a failure in the roofing near the roof edge and brick wall. Also confirm you don't have any damaged bricks above and the mortar joints are sound. Maybe it's time to repoint.

   Pro-Dek:

   My wife does keep quite a few plants in the sunroom.  When it turns cold, she moves all of the outdoor plants to the sunroom.

   Thanks,

   Stan
