Moisture intrusion refers to water getting into a building and is one the most significant factor affecting the durability of a building envelope, which is its ability to continue to perform its functions over time. Building moisture can cause mold, fungal growth and other microbial contamination, as well as corrosion, decay, rot and other moisture related deterioration. These issues can pose serious health risks for occupants, and will likely lead to costly repairs to correct the problems that first allowed moisture to invade.
The basic causes of moisture intrusion into buildings, both liquid and vapor, include:
- Infiltration of rainwater/groundwater: significant amounts of moisture can enter a building through leaks in the envelope. Rain and groundwater can be drawn into a building though capillary action, surface tension, gravity, wind, and differences in air pressure.
- Infiltration of moist outside air: humid air from outside the building can be introduced by air infiltration through openings in the envelope or through the HVAC system. This is a significant problem in hot and humid climates.
- Moisture created within building: the daily activities of the occupants of a building and routine housekeeping procedures can generate additional moisture within the building itself.
- Diffusion of water vapor through building envelope: differences in water vapor pressure between the inside and outside of a building can cause water vapor to pass through the building envelope. This is a significant problem in cold climates. Small amounts of moisture within a building will condense inside the cavities of cold walls during winter months.
A moisture inspection can determine current issues and prevent further damage to the home.

Rochester Basement Moisture Issues
Basement moisture is one of the most prevalent problems we encounter during moisture inspections in Rochester, MN. The region's soil composition, which includes significant clay content throughout Olmsted County, plays a major role. Clay soil expands when saturated and contracts when dry, creating hydrostatic pressure against foundation walls and opening pathways for water infiltration. During spring thaw, when several feet of accumulated snow melts over a short period, the volume of water seeking a path of least resistance can overwhelm even well-constructed foundation drainage systems. Our moisture inspection uses professional-grade moisture meters and thermal imaging cameras to detect water intrusion that is hidden behind finished walls, under flooring, and in areas that are not visible during a standard visual inspection.
Humidity Control and Condensation
Even in homes without active water leaks, excessive humidity can create serious moisture problems in Rochester. During Minnesota's humid summer months, warm moist air can condense on cooler basement surfaces, creating conditions ideal for mold growth and wood rot. In winter, improper ventilation in attics and crawl spaces leads to condensation that damages insulation and structural components over time. Our home inspector measures relative humidity levels throughout the home and identifies areas where condensation is occurring or likely to occur based on temperature differentials and air circulation patterns.
Moisture Meter Testing and Thermal Imaging
We use both pin-type and pinless moisture meters to evaluate materials throughout the home. Pin-type meters measure moisture content within wood framing and finish materials, while pinless meters allow non-destructive scanning of larger areas to locate hidden moisture pockets. Thermal imaging reveals temperature anomalies that indicate the presence of moisture behind walls, around windows, and in ceiling areas. This combination of testing methods provides the most accurate assessment of moisture conditions in your Rochester home. If our moisture inspection reveals elevated moisture levels, we recommend pairing it with our mold testing inspection to determine whether mold growth has begun.
