Indoor Pools, Moisture, and Related Problems
Visible mold growth
Discoloration of wood and other building materials due to water stains
Weakening of the wood due to rot
indoor air quality
Moisture laden air moves into wall/ roof cavities and condenses when it comes in contact with the cooler surfaces.
High levels of relative humidity, in conjunction with indoor temperature changes, create moist surfaces where mold and mildew can grow
Missing or incomplete vapor retarder
Perform initial building diagnostics and testing to identify causes of the problem. Tests may include infrared thermography, blower door testing, or temperature and humidity monitoring.
Isolate the climate controlled spaces.
Review the condition of vapor retarders
Seal any air leaks resulting from infiltration or exfiltration from the building. Creating a tight building envelope is the first step to
controlling the indoor environment.
If necessary, recommend the installation of mechanical ventilation systems to control the movement of air/moisture in and out of the building.
