Humid conditions within an in-door environment may cause black mold growth to occur on the frames of your windows. This condition is usually common when organic debris deposits itself to the window frame, with the help of water vapor condensation on the cold metal frame of the window.
Black mold found on window frames can often be cleaned with an EPA-approved microbial solvent. Always conduct a black mold investigation to determine if the condition is superficial or more complex.
