Understanding Crawl Space Humidity in Florida

How damp, humid crawl space environments affect your home

No ifs, ands, or buts: crawl spaces are filthy, and believe it or not, they were pretty much built to be that way―just a side-effect of the way homes were constructed in the past. If that creepy gap beneath the first floor of your home is so scary you don't even want to peek your head underneath to see what's happening, then maybe it's time you called LRE Foundation Repair for a free crawl space humidity and mold remediation inspection for your Tampa home.


When moist air enters a vented crawl space, condensation occurs on cool crawl space surfaces.

How crawl space humidity begins

Humidity in the crawl space of your home can lead to serious structural problems. Mold will begin to grow, and the wood beams that support your floor will begin to rot. As the floor beams rot, the floor becomes uneven and may even sag, and if left unattended, sections of your floor could possibly cave in.

Here's the key point: If the air outside is wet or humid, then your crawl space vents are bringing in moisture. You may even need a mold remediation service on your home in Tampa if the humidity damage is severe.


What humidity does to crawl space

Mold and rot also invite unwanted pests, like termites, carpenter ants, wood-eating beetles, crickets, and an assortment of furry critters. As the rot increases and animals begin to die and decay in your crawl space, the stink begins, which means mold spores and allergens are rising into your home, which is unhealthy for anyone, particularly people with allergies, asthma, or other respiratory difficulty.

On hot summer days, humidity in the crawl space will increase your cooling bill. A window-mounted air conditioner is made to dehumidify the air it cools, but if your crawl space fills your home with humid air, your air conditioner is probably losing the battle.


Wood that stays damp in a dark crawl space is an ideal mold habitat. Eventually, mold causes wood decay that can destroy structural parts of the house.

  1. Warmth
  2. Moisture
  3. Food

Of these, the easiest to control in your home is moisture.
