Paston Effect Humidity Problems
When conditions such as elevated humidity, condensation, moldy AC ducts, sweaty AC ducts, mold, or mold odors, are detected in the attics of two story homes in coastal regions The Paston Effect may be the problem. This problem does not stay in the attic but often eventually spreads to the rest of the house.
This condition occurs when hot humid ocean breezes blows into the attic via soffit vents and causes humidity in the attic to rise and attic ductwork to reach dew point.
Excessive mold grows on the outer surfaces of condensation covered ducts ducts, this mold is almost always invisible to the untrained eye but occupants know their is mold because they smell mold odors or have allergic reactions or asthma attacks when in the house. Also Condensation will drip down from the sweating AC ducts and stain the ceilings below.
The moldy smelly attic air eventually gets worse and breezes blowing into the soffits causes the attic air to pressurize and enter habitable areas below. The moldy air escapes from the attic by blowing through hallow wall cavities below, and through wiring holes hidden above ceiling mounted light fixtures, or through holes hidden inside the housing of recessed lights and other openings including attic access covers.
Sealing these openings will not help because the problem will continue to fester and get worse in the attic.
Mold odor and moist air will eventually find it’s way out even through your electrical outlets and light switches where the condensation will form halos around light switches and outlets.
Whenever we have investigated homes with Paston Effect problems the homeowners have typically dealt with the problem for many years and have spent much money on non effective attempts to correct the problem.
Maintenance men, mold inspectors, AC contractors, and friends of the homeowners all have opinions and ideas on how to deal with this humid air problem creeping into the home from the attic but none seem to work.
Correction may not involve increased ventilation, because this might just let additional outdoor humidity into the attic. In addition it is more complex than simply sealing the attic as this may cause new problems.
The solution is a multi step process that must be done correctly and tailored to your homes specific needs.
Correction will require professional inspections and consultation from a trained and qualified certified indoor environmentalist, engineer, or certified industrial hygienists who has experience investigating this specific complex issue. Question your inspector if he or she has no experience with this humidity problem then call someone else.
