Mold can be caused by a number of different factors, including water damage, rising humidity levels, and improper ventilation. There are certain areas of the home that tend to be more vulnerable than others to mold growth. To help you better understand when mold testing may be necessary, here are a few areas of the home that are most susceptible.

3 Parts of a Home Susceptible to Mold

1. Top-floor Ceilings

A top-floor ceiling may be your only barrier between the interior of your home and the dark, wet spaces of an attic or a roof underlay. Leaking rain, snow, or ice; high levels of humidity; or lack of attic air vents can cause mold growth on a ceiling, especially one on the top floor. Signs to look out for include yellowed or greenish patches and cracked or peeling paint.

2. Bathroom & Kitchen Walls

While any wall can be damaged by water, there is a higher likelihood that leaks will occur in the two rooms with sinks—the kitchen and the bathroom. Where there is water, there is also the possibility of mold. If not treated by a mold testing and remediation professional, a growth on a wall could cause anything from an allergic reaction to severe respiratory distress. Look for discolored patches on the wall, musty or stale odors, and bulging areas.

3. Windowsills

Because a windowsill is prone to getting wet, it creates the perfect environment for mold to grow. If not treated and removed by a mold testing service, a growth in a windowsill can continue expanding as long as condensation and dampness are present. Like all types of mold, health concerns to be aware of include a flare-up in allergies, coughing, congestion, and sinus issues. Mold on a windowsill is typically visible with the naked eye, but it will likely start in the darkest places of the sill, like the tightest corners or under the window seal.
