Bay Area sump pump company, E-Mora Construction has helped San Francisco Bay Area homeowners solve their home moisture and humidity problems since 1998. E-Mora offers advice on how humidity and moisture problems can damage crawl spaces and what it can do to solve the problem.

Crawl space humidity has been plaguing homes in California since they were first built. As the spaces become increasingly humid, moisture will condensate on the surfaces in the crawl space, leading to serious problems in the home.

As humidity builds in the crawl space, it creates an ideal space for mold and rot to grow. As this happens, all organic material in the crawl space will be damaged, including wooden floorboards and support beams. Most of the problems traditionally associated with damaged, rotting crawl spaces are due to basic flaws in the way that crawl spaces were designed.

Crawl spaces and basements are well known for being damp, dank spaces. Even when one's home has no groundwater flooding issues and has perfect plumbing, the spaces can be plagued by moisture issues. One major culprit for humidity in the home is a phenomenon called the "stack effect."

"The stack effect refers to the process in which hot air leaves the home through the attic and upper levels," Ernesto Mora, owner of E-Mora Construction, said. "As it does, a vacuum is created below, and new air is pulled upwards through the basement, crawl space and lower levels."

If one has crawl space vents, they will also become part of the air movement in the home. As air is pulled out of the crawl space and up into the home, new air will be pulled in through these vents.

Crawl space humidity leads to all of the following problems in a home: rotting and mold, rusted and corroded metal, odors and allergens, and higher utility bills.

One method to decrease moisture and the chance of rot and mold in crawl spaces is to install the moisture barrier system, which is a 20-mil thick polyethylene moisture-barrier, using non-bio-degradable plastic anchors and/or polyurethane caulking.

Aside from the moisture barrier system, E-Mora Construction also provides other water drainage and moisture removal solutions, including sump pump installations, perimeter drains, french drains and trench drains, as well as crawl space cleanup, ventilation and insulation.
