A certified inspector maps the moisture you can't see - behind walls, under floors, above ceilings, and around fixtures - using infrared thermal imaging plus pinless and pin-probe moisture meters. You get same-day verbal findings and a photo-documented written report within 48 hours, so you know whether water has gotten in before it turns into mold. For homes, rentals, and commercial buildings across LA, Ventura, and Orange Counties.
Moisture testing is the diagnostic step that answers one question: did water get into the building, and if so, where? It is the look behind the surface, before mold has a chance to start.
Water hides. A roof leak, a burst supply line, wind-driven rain, or a slow drip under a sink can leave materials wet long after the surface looks dry, and that trapped moisture is what feeds mold within a day or two. During a moisture test, a certified inspector scans the suspect areas with an infrared thermal camera to spot the temperature differences that wet materials create, then confirms each finding with moisture meters - a pinless meter for fast surface mapping and pin probes where a reading suggests deeper saturation. We document everything with photos and translate the readings into a written report you can act on.
This is a focused, equipment-based diagnostic. It is the right call when you suspect a leak or water intrusion rather than a mold problem - after a storm, after a plumbing event, before a renovation, or during due diligence on a home purchase. If a musty smell has you wondering whether something is growing, a mold inspection is the better starting point, since it adds mold-specific evaluation on top of the moisture readings.
Infrared imaging on its own is available as a simpler thermal imaging scan for $149. Moisture testing at $229 goes a step further: it pairs the thermal camera with calibrated moisture meters and pin probes, so a thermal anomaly is verified with an actual moisture reading rather than left as an image to interpret. The meters are what turn "this area looks cooler on the camera" into "this wall is reading elevated moisture at this depth."

Every $229 moisture test covers the same equipment-based diagnostic, from a single suspect wall to a whole home checked after a storm.
Time on site: 45 to 75 minutes for most homes.
Format: Contractor- and adjuster-ready PDF.
Best for: Post-leak follow-up, pre-purchase, or pre-renovation.
Your test is run by a certified mold inspector who knows what early moisture means for mold risk and reads to a recognized industry standard. We pair an infrared thermal camera with calibrated pinless and pin-probe moisture meters, so the findings are measured and documented rather than guessed. If a reading suggests mold may already be taking hold, lab confirmation steps up to our partners Eurofins (AIHA-LAP accredited, ID #173068) and BTLS (ASTM-standard methods, Tarzana) through our mold testing service.
$229 flat for a standard moisture test. The price you're quoted is the price you pay - travel inside county lines and the written report are included.
The moisture testing cost is $229 for a standard home, covering the infrared thermal scan, pinless and pin-probe meter readings, an assessment of likely moisture sources, photo documentation, same-day verbal findings, and the written report within 48 hours. Larger homes, commercial spaces, and properties with several suspect areas are quoted before we book, so the number is clear ahead of time.
The most common reasons people ask "how much does moisture testing cost" are a recent leak or storm, a musty smell with nothing visible, a pre-renovation check, or due diligence before buying. In each case, a focused moisture map tells you whether water got in and where - so you can dry it out, repair it, or rule it out before it becomes a bigger problem.

Tell us what's going on. We confirm a time - same day inside our 25-mile core, next day everywhere else - and lock in the $229 flat rate.
We sweep the suspect areas with the infrared camera, then confirm each anomaly with pinless and pin-probe meter readings, documenting as we go.
Before we leave, we walk you through where moisture showed up and how wet it is - in plain language - while we're still on site.
We assemble the thermal images, meter readings, and likely sources into a clear written record you can hand to a plumber or contractor.
Within 48 hours you'll have the complete report. If the readings point toward mold risk, we'll point you to a mold inspection as the next step.
