May 16, 2025 by

Basements naturally tend to trap moisture—and over time, that humidity can wreak havoc on your home. At BelowDry Basement Waterproofing, we’ve seen firsthand how prolonged basement humidity affects homes in Rochester, Buffalo, and throughout Western New York. Whether you’re dealing with musty smells or structural concerns, it all starts with too much moisture in the air.

What Causes High Humidity in Basements?

Basement humidity is often the result of poor ventilation, water seepage through foundation walls, or high groundwater levels. Leaky sump pumps, cracks in the concrete, or even humid summer air infiltrating the space can all contribute to excessive moisture levels. And once that humidity sets in, it rarely goes away on its own.

How Humidity Affects Your Basement Over Time

  • Mold Growth: Persistent moisture creates the perfect breeding ground for mold and mildew, which can spread quickly and cause health issues like asthma and allergies.
  • Wood Rot & Rust: Support beams, stairs, and other wooden elements may rot, while metal fixtures can rust, weakening your basement’s structural integrity.
  • Foundation Damage: Moisture trapped in walls can freeze and expand during cold months, worsening cracks and compromising the stability of your foundation.
  • Air Quality Issues: Because air rises from the basement to the upper levels of your home, basement humidity can spread pollutants and allergens throughout your living space.

How to Control Basement Humidity

Thankfully, there are several effective ways to keep your basement dry and healthy:

  • Install a Sump Pump: A properly installed and functioning sump pump can prevent water from pooling and reduce humidity.
  • Use a Dehumidifier: A quality basement dehumidifier helps maintain safe moisture levels year-round.
  • Waterproof Your Basement: Sealing cracks, installing drainage systems, and applying waterproof coatings can protect against water intrusion.
  • Ventilation Improvements: Installing vents or exhaust fans improves air circulation and helps control humidity.
