HELP!! We have a wood sided home painted with a exterior latex stain(good quality paint with mold protection) about 4 years ago. The home has developed a black mold starting on the northeast side of the home. We have cleaned the siding with commerical grade exterior mold solvents using a power washer. The mold keeps coming back and we are now noticing the mold on all four sides of the exterior and in our screened in porch. The last time we cleaned it with Clorox bleach. It is still coming back. We are willing to repaint the house but are affraid the mold will come through. Any suggestions? We have contacted serveral contractors and our homeowners insurance company but are not getting anywhere.

Mold and mildew rely upon a source of moisture and an uncleaned surface for their growth. Sources of moisture to eliminate may include: Large plants growing close to house, vines growing on the house, moisture entrapped from poor ventilation of an attic, moisture accumulating from sprinklers spraying on the house, exterior moist air condensing on a surface through which air conditioning is leaking. Some houses don't dry well after rains, because of poor air flow. Nevertheless, it sounds as if the location of the mildew is not a part that would become wet in a rain.
Finding and removing the source of moisture for the mildew is the first thing to do. Otherwise, it will keep returning. After the source is removed, wash the house with bleach 25% in water with some tide, and rinse clean. See Guidelines about bleach. After that, the problem should be resolved.
Painting over the unresolved problem will not solve it. Additives to paints and stains may help, but will not keep the mildew away unless the source of moisture is eliminated.
Your insurance company is not likely to cover this maintenance problem. If you hire a contractor to remove the mildew, there must be more done that putting something on it. The contractor or you will have to eliminate the source of the problem.
Hope this helps.
