- Attics: Should match outdoor conditions
- Bathrooms: Should return to normal levels within 2 hours after use

Strategic Placement
Place hygrometers in basements, bathrooms, kitchens, and any areas with previous water issues. Monitor seasonal changes and investigate sudden spikes.
5. Thermal Imaging Cameras – Professional-Grade Detection
Advanced Water Detection
Thermal imaging cameras reveal temperature differences invisible to the naked eye, making them excellent for detecting hidden water damage, insulation issues, and air leaks.
Consumer Options
- Smartphone attachments: $200-$400 for basic thermal imaging
- Dedicated cameras: $500-$2000 for professional features
- Rental options: Many tool rental shops offer thermal cameras
What You’ll See
- Darker/cooler areas: Often indicate moisture or water damage
- Thermal bridges: May show missing insulation allowing condensation
- Temperature gradients: Can reveal active leaks behind walls

Best Practice
Use thermal imaging during temperature extremes (hot summer days or cold winter nights) for maximum contrast. Document findings with both thermal and visible light photos.
6. Flashlights and Inspection Lights – Essential for Visual Detection
Why Proper Lighting Matters
Many early signs of water damage hide in dark, hard-to-reach areas. Quality lighting is essential for thorough inspections.
Recommended Features
- LED technology: Bright, energy-efficient, long-lasting
- Rechargeable batteries: More reliable than disposables
- Adjustable beam: From wide flood to narrow spot
- Magnetic base or clip: Hands-free operation
- Water resistance: IPX4 rating or higher
Inspection Areas
- Crawl spaces and basements
- Under sinks and behind appliances
- Attic spaces and roof areas
- Around windows and doors
