Moisture Intrusion Investigations
Find where the water comes from — and where it goes.
Short answer
A moisture-intrusion investigation traces water to its source and follows where it travels. Using moisture meters, thermal imaging, and building-science reasoning, Sterling evaluates roofs, plumbing, windows, HVAC condensate, and grading — because correcting the moisture source is what actually resolves a mold problem.
What this service investigates
- Roof, flashing, and ceiling leaks
- Plumbing supply, drain, and fixture leaks

Where Florida homes hide moisture.
Explore the zones we investigate on every inspection. Finding and correcting the moisture source is what actually resolves a mold problem — and prevents it from returning.

Attic & roof deck
High riskWarm, humid air rises and condenses on cool roof sheathing. Bath fans venting into the attic and undersized ventilation drive recurring growth here.
Methods & equipment
- Pin and pinless moisture meters
- Infrared thermal camera
- Hygrometer
- Borescope where accessible
What you receive
- Moisture map and readings
- Thermal documentation
- Findings on likely sources and pathways
- Recommended corrective next steps
Typical timing
Investigations are performed on-site; complexity and access determine how long the visit takes. The written summary follows shortly after.
Pricing
Cost depends on property size, access, and how much of the building must be evaluated. Request an estimate.
Moisture Intrusion Investigations — questions
No. Air sampling can indicate spore levels but cannot tell you where water is entering. Finding and correcting the source is a separate, essential step — and the one that prevents recurrence.
