Here’s Why, and What You Can Do
This summer’s persistent rain and heavy humidity have put homes across Virginia to the test.
At Viridiant, we’re hearing from more homeowners experiencing high humidity in their homes, excess moisture in crawlspaces, lingering indoor humidity, and even foundation concerns. If your home feels muggy or you’re noticing signs of water infiltration, you’re not alone.
Why It's Happening
With some exceptions, this summer hasn’t been especially hot, but it has been unusually wet. Your air conditioner may not be running as much, or for as long, this summer — which means it’s not removing as much moisture from the air.
An AC, regardless of its efficiency, only removes moisture while running, and longer run times are most effective for reducing humidity.
That moisture can build up and can lead to discomfort, musty odors, condensation, and even long-term structural or indoor air quality problems.

What to Do About It
There’s no one-size-fits-all solution for every home. Be cautious of generic sales pitches that claim otherwise. The right approach depends on your home’s construction, location, HVAC system, and even your lifestyle. At Viridiant, we take a whole-house approach to improving comfort, health, and efficiency.
That means looking at:
- Crawlspace condition – Is it sealed, insulated, and properly ventilated or dehumidified?
- Air sealing and insulation – Are moisture and outdoor air leaking in where they shouldn’t?
- HVAC system performance – Is your system properly sized and effectively controlling humidity?
- Ventilation strategies – Are you bringing in fresh air in a controlled and balanced way?
- Duct leakage – Are your ducts leaking cold air into unintended spaces or pulling in moist outdoor air through return leaks?
A Better Path Forward
Excess humidity isn’t just uncomfortable, it can be a sign of underlying problems that threaten your home’s integrity and your family’s health.
