We have had a growing problem with mildew in several areas: 1. At the NE corner of the house, 2nd floor interior room and a few areas of the wall-eiling joint. 2. At the SE corner of the house, 2nd floor interior room. This area also had ice crystals visible in the winter. Several streaks along the wall-ceiling joint. 3 Around three interior "set-into-the-ceiling" type recessed lights. 4. In an interior hallway that has a drop down stairs from the attic. This is a hallway of about 15' long, no ventilation vents and is air conditioned via air flow through area. In summer the walls are visibly wet. The entire ceiling is a real mess!
In fall of 1999, we had a new roof put on the house with several vent fans installed that have automatic heat and humitity sensors that activate the venting process. The hall was better with somewhat less moisture and the house corners and around the lights did not seem to get bigger this past year.
We have used bleach and water to clean the mildew areas. Of course it is still an unsightly mess! We have drywall with unpainted plaster compound finished in a stipled technique. We want to paint the ceilings and walls and not have the mildew reappear EVER again. Our home is 26 years old and otherwise is in excellent shape.
Please tell us if we are doing this right. My husband says we still need to find a better way of keeping the heat in the attic as the condensation in the hall has not gone away enough to think that IT'S over in that area.
We would appreciate any help you can give us in techniques or product to use.
