In Reply to: Mold On Inside Walls Of Home Posted by: K.Leavitt on December 30, 2000 at 00:43:38

I have a problem with mold on the inside of my home. The house had been sided over with aluminnum siding, and has new vinyl double pane windows and plenty of insulation in the ceiling. The mold is growing on the inside of the outside walls of the house. What do I need to do to get rid of it? Thanks.

Since you state that you have plenty of ceiling insulation and do not mention wall insulation, my suspicions are that you have little to no wall insulation. This would support mold growth by having warmer moist interior air to condense on colder exterior walls.

Only solution in this case is to insulate the walls, because even low relative humidity on the inside will still condense if the walls are cold enough.

If the walls HAVE been insulated using cellulose, it does have a tendancy to compact over time leaving as much as 50% of the wall cavity uninsulated. The uninsulated space would foster mold growth as Chris mentioned.
