Went to do some cleaning in the garage, noticed some black lines on the ceiling. Also had noticed something on the ceiling of the main bathroom for some time before noticing the spots in the garage.
The garage and attic are not temperature controlled, the main floor and the basement have a retrofitted central air. Ranch house with one main floor, and an small attic above, on a slope so the basement is under the kitchen/living room/main bath and extends to to a garage that is underneath the bedrooms but can walkout from it.
Note: it has a been an extremely rainy season, so the mold may have appeared faster than it would have normally
Not very handy. Help!
