As temperatures rise and the snow melts away, April brings a breath of fresh air to the Chicago area—but it also brings the perfect storm for mold growth. At Not Your Average Mold Guys, we see a spike in mold-related calls every spring—and for good reason.

If you’re a homeowner in Chicagoland, April is the time to get ahead of hidden mold before it becomes a costly and unhealthy problem.


Why Is April a High-Risk Month for Mold?

After a long winter, your home starts to warm up and breathe again—but that also means:

  • Increased humidity from spring rains and thawing snow

  • Poor ventilation in closed-off winter spaces like basements and attics

  • Leaks and moisture that went unnoticed during the colder months

  • Clogged gutters or poor drainage leading to water seepage

These factors combine to create the perfect conditions for mold spores to grow and spread.


Common Places Mold Hides in April

During April inspections in Chicago homes, we commonly find mold in the following areas:

1. Basements

Melting snow and April showers often mean damp basement walls or floors—especially in older homes with poor waterproofing. Even small leaks can lead to significant mold colonies behind drywall or in carpet padding.

2. Attics

Poor insulation, roof leaks, and improper ventilation often go unnoticed until spring. Mold loves to take hold in attic rafters, insulation, and sheathing, especially after months of condensation buildup.

3. Windowsills & Trim

As condensation forms more frequently in April (when daytime temps rise and nights are still chilly), mold can begin growing around windows—especially wood-framed ones.

4. Bathrooms

Increased humidity from long, hot showers with poor ventilation makes bathrooms a top offender for mold in the spring.

5. Crawl Spaces

Most people don’t check their crawl spaces often—but mold thrives here in April when the ground is damp, ventilation is minimal, and wood structures are exposed.


Signs You Might Have Mold

Not all mold is visible right away. Be on the lookout for these red flags:

  • Musty or earthy odors, especially in basements or near vents

  • Peeling paint or bubbling walls

  • Dark patches on walls, ceilings, or baseboards

  • Increased allergy-like symptoms in your household

  • Warped wood or discolored drywall

If you notice any of these signs, it’s time to schedule a professional inspection.


Why April Mold Shouldn’t Be Ignored

Ignoring mold now can lead to:

  • Structural damage to your home

  • Respiratory issues, especially for kids or people with asthma

  • Higher remediation costs if mold spreads unchecked

  • Compromised air quality from hidden spore circulation

Mold isn’t just a cosmetic issue—it’s a health and safety risk, especially in humid transitional months like April.


How to Prevent Spring Mold in Chicago

Spring mold prevention doesn’t have to be difficult. Here are a few tips to protect your home in April:

✅ Inspect Your Basement

Check for signs of seepage, leaks, or musty smells. If your sump pump hasn’t been checked in a while, now’s the time.

✅ Check Your Roof and Attic

Inspect your roof for missing shingles or flashing. Look inside your attic for signs of wet insulation or wood discoloration.

✅ Clean Your Gutters

Clogged gutters can cause water to spill over and pool around your home’s foundation—leading to basement leaks and wall mold.

✅ Ventilate

Open windows on mild days to let in fresh air. Run exhaust fans in bathrooms and kitchens regularly.

✅ Use a Dehumidifier

April humidity can fluctuate drastically. Running a dehumidifier in key areas (like the basement) helps keep moisture below mold-friendly levels.
