Mold isn’t just unsightly, but a health hazard as well. Of the many varieties of mold, most can have harmful effects ranging from allergy symptoms to permanent respiratory damage. Keeping an eye out for mold is essential to keep your family safe. Roofing contractors say, along with the basement and attic, the windows are another common place to find mold growth.

The Causes of Mold

Mold requires moisture to grow; on the windows, moisture typically occurs as condensation, which forms when indoor and outdoor temperatures converge. This is usually a result of air leaks or windowpanes that are too thin. The lack of insulation allows outdoor air to come in, causing condensation to develop as the temperature on the window fluctuates. Mold can also grow if you forget to close the windows during rainstorms and don’t properly dry the area. It can begin to grow within 24 to 48 hours after water exposure.

How to Prevent It

Determine the source of the problem to prevent it from happening again. Simple maintenance, such as caulking around the windows, sealing leaks, and wiping down the tracks with a bleach and water solution will help. Keep your gutters clear to ensure a blockage doesn’t cause water to accumulate under the roof or near the windowsill outside, resulting in a moist environment. Check the attic as well for mold spores and roof leaks.

When to Replace the Windows

If there is internal damage from the mold, you’ll want to replace the windows. You may notice the frame is pulling away from the wall or the sill feels loose. Replacement is also wise if the windows are old and single-pane or damaged, resulting in reduced energy efficiency and insulation.
