Spring in Michigan brings warmer weather, blooming trees, and unfortunately… mold. Between snowmelt, heavy rain, and rising humidity, this time of year is prime for moisture problems—and mold is usually right behind them.
If you’re a homeowner, contractor, or property manager, here’s what you should know before that musty smell turns into a bigger issue.
Why Spring = Mold Season
As the weather warms up, the ground thaws and rainwater has nowhere to go. Basements, crawlspaces, and poorly ventilated areas become damp, creating the perfect environment for mold spores to grow. Even small leaks or condensation can lead to problems if left unchecked.
And once mold takes hold, it spreads fast. Not only does it damage building materials, but it can also lead to respiratory issues for occupants.
Warning Signs to Watch For
A persistent musty smell (especially in the basement or attic)
Visible spotting on walls, ceilings, or around windows
Water stains that never fully dry
A recent leak or flood—even if it seems “cleaned up”
Don’t wait for visible mold to take action. By the time you see it, it’s likely been there for a while.
