Leak detection and Investigating Services

At We Know Mold, stopping water damage at its source is just as important as drying it out. Identifying the true origin of a leak ensures the problem doesn’t return—and helps protect your property from mold, rot, and structural damage.

Our certified technicians combine years of field experience with advanced tools and building science knowledge to locate and eliminate moisture at the root.

• Damaged shingles, flashing, or underlayment can let rainwater enter attics or ceiling cavities.
   
• We inspect rooflines, skylights, chimney flashing, and attic insulation for signs of intrusion.
   
• Infrared thermal imaging and moisture meters help trace water paths behind ceiling surfaces.
   

• Poorly sealed or aging window/door frames are common entry points for wind-driven rain or condensation buildup.
   
• We check for soft drywall, peeling paint, musty smells, and window sill staining.
   
• Using moisture probes, we test around framing to confirm active leaks.
   

• Leaks behind walls, under sinks, or in crawlspaces often go undetected until damage is severe.
   
• We pressure-test plumbing lines, inspect visible pipes, and use acoustic and infrared tools to locate hidden leaks.
   
• Hot spots on thermal imaging may indicate hot water leaks under floors.
   

• In basements or lower levels, high water tables or poor drainage can force water up through slab cracks or foundation walls.
   
• We check for efflorescence (white residue), water staining, and sump pump performance.
   
• Exterior grading, downspouts, and drain tile systems are evaluated as part of our investigation.
   

• Improper insulation, poor ventilation, or leaky AC units can lead to moisture buildup and mold—especially in walls or attics.
   
• We inspect HVAC units, ductwork, and cold air returns, and monitor for high relative humidity levels.
   
• Condensation from duct sweating or poorly sealed vent boots is a common issue in humid areas.
   

• Thermal imaging cameras to spot temperature differences caused by moisture
   
• Non-invasive moisture meters for drywall, wood, and flooring
   
• Hygrometers to measure humidity levels and dew points
   
• Borescopes for wall cavity inspections
   
• Dye testing and water tracing when necessary
   

Finding and fixing the leak is the foundation of any successful water damage restoration. If the source isn’t corrected, even the best drying or mold remediation won’t prevent future damage.

At We Know Mold, our goal is not just to clean up the mess—but to stop it from happening again.
