A ceiling stain that darkens after heavy rain tells a different story from an AC vent that sweats on humid afternoons. A musty smell near a carpeted wall may point to moisture that has spread into the padding. Those clues help narrow the search, and readings taken on site help determine what needs to be corrected.
At FixMold Miami, our moisture and mold inspections look at three common causes of recurring moisture problems in South Florida homes and condos: elevated indoor humidity, condensation and water intrusion.
When humidity turns into condensation
We measure indoor temperature and relative humidity to determine the dew point, the temperature at which moisture in the air can begin to condense on a surface. We then compare that dew point with the temperature of surfaces such as AC registers, ductwork and nearby walls.
If a register gets cold enough for condensation to form, we look at what’s contributing to the conditions around it. The inspection may include checking nearby insulation, looking for humid air entering around the opening and evaluating how effectively the AC removes moisture.
When water enters through a leak
Water can travel along framing, behind baseboards or beneath flooring before it leaves a visible mark. We examine the pattern of affected materials and check likely sources, including windows, roof details, exterior joints, plumbing and AC condensate drains. Timing can help narrow the search. A stain that changes after wind-driven rain gives us a different starting point from dampness that appears after the AC runs.
How we use the inspection equipment
- Infrared thermography shows surface temperature patterns. We use those patterns to choose where to take follow-up moisture readings.
- Moisture meters and Protimeter readings help us compare suspect areas with a dry area of the same material. On dual-mode models, we can screen a broader area with pinless mode and use pins for targeted checks.
- HydroSensor probes help us trace how far water has spread in carpet and padding, including beyond the visible wet spot.
From findings to source correction
The findings guide the scope. A leaking window joint, a condensate drain problem and persistent indoor humidity each call for a different correction. We explain what we found, where the moisture spread and what needs to happen before the affected areas can be considered dry. Follow-up readings and photos help document the work.
