The most expensive preventable problem we face in Portland is moisture intrusion in our homes. Leaks can go unnoticed for years causing extensive damage before the moisture is visible. Fortunately, we have equipment that allow us to see moisture through walls and floors. It's like x-ray vision without x-rays.
Anatomy of a Water Leak

When water gets behind walls it creates cold spots because of exterior temperatures and evaporation. Our cameras are so advanced we can see temperature differences of one degree.
The green and yellow areas of the infrared photo are only 2-3 degrees colder than room temperature but allow us to easily see high moisture in the ceiling. So, how did we know the infrared camera was showing moisture? Keep in mind there was no visible evidence of a leak, not even a stain.
We use electromagnetic pulse wave moisture meters that can determine the exact moisture content of walls to a depth of 3/4". It can detect moisture through tile, wood, drywall and concrete. Once we know the moisture content it can help determine if it's high enough to grow black mold and rot.
We use moisture meters on every interior and exterior wall of the home and around all plumbing fixtures. The infrared helps us identify other areas areas of concern that are difficult to get to like vaulted ceilings, second stories and skylights. After every moisture scan you'll get a report with infrared photos and a detailed list of our findings. * Note: We do not inspect, evaluate or give opinions on any structural components. We only identify and describe areas of high moisture using the equipment described above. Any further evaluation will need to be done by a licensed contractor.
Moisture scanning and infrared are a perfect addition to mold testing. If there's high moisture there's always mold. You can't do anything about mold unless you first find the moisture.
