The Root Cause Behind Mold, Comfort Issues, and Indoor Air Quality Problems

In Florida, humidity is not just a comfort issue, it is a building performance issue.
Excess moisture inside a home creates the perfect conditions for:
  • Mold growth
  • Dust mite proliferation
  • Material deterioration
  • Poor indoor air quality
At Building Performance Solutions, we don’t just measure humidity, we identify why moisture is present and how it’s being introduced, distributed, and trapped within the home.

Why Humidity Problems Are Often Misunderstood

Most homeowners are told:
  • “You need a dehumidifier”
  • “Your AC isn’t running enough”
While sometimes true, these are often symptoms, not root causes.
Humidity problems are typically driven by:
  • Air leakage from outside or attic spaces
  • Negative pressure pulling in humid air
  • Improper HVAC design or airflow issues
  • Duct leakage introducing unconditioned air
  • Poor ventilation strategies
  • Building envelope deficiencies
If you don’t identify the source, the problem will continue.

Our Approach: Diagnose the Whole System

We approach moisture issues using building science principles, not guesswork.

Our diagnostics may include:
  • Relative humidity and temperature profiling
  • Dew point analysis
  • Infrared imaging to identify thermal anomalies
  • Blower door testing (air leakage pathways)
  • Duct leakage testing (moisture entry via HVAC system)
  • Pressure diagnostics (identifying negative pressure zones)
  • Visual inspection for water intrusion or condensation
This allows us to answer:
  • Where is the moisture coming from?
  • How is it entering the home?
  • Why isn’t it being removed?
  • What conditions are allowing mold to grow?
Common Moisture Issues We Identify
  • Elevated indoor humidity despite AC operation
  • Condensation on windows, vents, or surfaces
  • Musty odors or suspected hidden mold
  • Moisture intrusion from exterior walls or roofs
  • Humidity imbalance between rooms
  • HVAC systems that are oversized or improperly configured
  • Duct systems pulling humid attic air into the home

Why This Matters for Indoor Air Quality

Moisture is one of the primary drivers of poor IAQ.
When humidity remains elevated:
  • Mold can grow within 24–48 hours on organic surfaces
  • Dust mites thrive and increase allergen levels
  • Airborne particulate levels often increase
  • Odors and VOC interactions become more pronounced
Controlling moisture is one of the most important steps in creating a healthy indoor environment.

What Makes BPS Different

Most companies measure humidity and recommend equipment.

We diagnose the cause.

Building Performance Solutions:
  • Uses advanced building diagnostics, not assumptions
  • Integrates HVAC performance with envelope conditions
  • Identifies source + pathway + driving force
  • Provides targeted, long-term solutions
  • Specializes in homes with persistent or complex moisture issues

When Should You Consider Moisture Diagnostics?

  • Indoor humidity consistently above 55–60%
  • Musty odors or mold concerns
  • Condensation forming inside the home
  • Recent or past water intrusion issues
  • Uneven comfort or humidity between rooms
  • Health symptoms that worsen indoors
  • Dehumidifiers that don’t seem to solve the problem

What Happens After Testing

You’ll receive:
  • Clear identification of moisture sources and contributing factors
  • Explanation of how your home is handling (or failing to handle) humidity
  • Prioritized recommendations for correction
Solutions may include:
  • Air sealing improvements
  • HVAC system adjustments or redesign
  • Duct sealing or modification
  • Ventilation strategy improvements
  • Targeted dehumidification (when appropriate)

Serving Florida Homeowners

We provide humidity and moisture diagnostics throughout Florida, including:
  • Southwest Florida
  • Tampa / Sarasota / Bradenton
  • Orlando and Central Florida
Our process is specifically tailored to hot, humid climate conditions, where moisture control is critical.

Schedule a Moisture Diagnostic Assessment

If your home has humidity issues, there is always a reason.

The key is identifying it correctly.

Don’t treat symptoms, solve the problem at its source.
