Tampa Bay Homeowners May Find A Conditioned/Closed Crawl space Is The Answer To Their Warped Subfloors, Condensation and Mold Under Their Homes!!!
There has been a great debate on whether to have a vented/open or closed crawl space. Vented crawl spaces worked great until the invention of air conditioning. When a family keeps their home cool at around 72-75 degrees and the air outside is 85 degrees with 80% relative humidity is drawn into an open cool crawl space it can create condensation on support beams, floor joists, insulation and pipes. Ventilation will not solve this problem with humidity so high. The consistent high humidity and condensation causes wood rot, mold and attracts all types of insects and termites in Tampa.
Closing a crawl space is now the standard for a lot of homes and will probably be part of the building codes in the near future due to energy efficiency reasons and prevention of wood decay and mold growth. Closing/conditioning a crawl space in post construction situations usually involves sealing vents, installing a vapor barrier if there isn’t one and installing a high capacity dehumidifier such as a Santa Fe unit made by Therma-Stor to permanently keep the humidity around 40-50%.
Symptoms of a moisture laden crawl space could be a musty odor in the living area ,buckling wood floors or popping tiles. How the mold gets started is that the warm humid air coming into the crawlspace from the outside is cooled in the crawl space raising the humidity providing excessive moisture for mold growth. 70%+ Relative Humidity for 24 hours is all it takes to get the mold going. This can also cause high humidity and mold growth in the living area when A/C units may not be running in the cooler months of the year in Tampa.
