Mold is On the Way
After the recent heavy rain, many homeowners may be breathing a sigh of relief now that the skies have cleared. But before you relax too much, there’s something important to watch for: mold growth.
Rain brings much-needed water to our environment, but it can also lead to unexpected problems inside homes and businesses — especially when excess moisture lingers unnoticed. Whether it’s a small leak in the roof, a damp basement, or water that seeped through doors and windows, mold can start growing in as little as 24 to 48 hours under the right conditions.
Why Rain Leads to Mold Problems
When a structure takes on moisture, whether through obvious flooding or hidden leaks, it creates the perfect environment for mold spores to thrive. Mold needs just three things to grow: moisture, warmth, and organic material (like wood, drywall, or carpet). After a rainstorm, all three of these factors are often present — and mold doesn’t take long to take hold.
Even if the water dries up quickly, materials inside the home may stay damp enough to allow mold to spread behind walls, under flooring, and in insulation, long before you ever see visible signs.
Signs to Watch For After Heavy Rain
Here’s what to keep an eye on over the next few days and weeks:
-
Musty odors: If a certain area of your home smells damp or “earthy,” it could be a sign that mold is growing somewhere hidden.
-
Visible discoloration: Look for patches of black, green, or white growth on walls, ceilings, floors, or in corners.
-
Water stains: Brown or yellow water stains on ceilings or walls can indicate that moisture got in and mold may not be far behind.
-
Peeling paint or wallpaper: Bubbling or peeling may be caused by moisture trapped behind walls.
-
Allergy symptoms: Increased sneezing, coughing, eye irritation, or respiratory issues can sometimes point to mold exposure — especially if symptoms improve when you leave the house.
What To Do If You Suspect Mold
If you spot any of these signs, it’s important not to wait. Mold can spread quickly and cause not only structural damage to your property but also serious health issues. Here’s what to do:
-
Inspect the areas that took on moisture: Check basements, attics, crawl spaces, around windows, and under sinks.
-
Use fans and dehumidifiers to help dry out damp areas.
-
Avoid disturbing mold if you find it — this can release spores into the air and make things worse.
-
Call a professional: A mold remediation expert can assess the situation safely, remove the mold correctly, and help prevent it from coming back.
Prevent Future Mold Growth
-
Fix leaks promptly: Whether it’s a roof leak or a dripping pipe, tackle it quickly.
-
Control indoor humidity: Try to keep humidity levels below 50% using air conditioners or dehumidifiers.
-
Ventilate damp areas: Make sure bathrooms, kitchens, and laundry rooms have good airflow.
-
Inspect your home after every storm: A quick check can save you a major headache later.
