0Florida’s humidity levels make moisture damage to your home a big concern. Excess moisture can cause structural and water damage, as well as mold and mildew growth, which in turn can lead to asthma and other health issues. Fortunately, there’s one simple way to control home moisture and eliminate these problems: air sealing.

Water vapor moving through air currents is responsible for nearly all the moisture in your home. The more outside air finds its way into your house, the more moisture you’ll have. And most drafts come in through the attic. So to help control home moisture, start by sealing your attic.

  • First, find the leaks where air is coming in. Common places include where the walls meet the floor, drop soffits (or areas with a lowered ceiling), behind and under knee walls and anywhere there’s dirty insulation.
  • To seal up these air leaks, begin with the larger holes. Use caulking or spray foam to seal gaps and cracks. Look around for any place that has dirty insulation, particularly in soffits and stud cavities and around knee walls. Dirty insulation means that air is getting in, so remove the insulation to seal up the leak, then put it back when you’re done.
  • For soffits, place foam board insulation over the opening and seal it with caulking. The opening behind a knee wall can be blocked with foam board and sealed with expanding foam.
  • Areas around furnaces and water heaters are a little different. Due to their high temperatures, they should be sealed with aluminum flashing and heat-resistant caulk. And keep insulation at least one to two inches away from metal pipes or flues.

Follow these tips to a well-sealed attic and you can better control home moisture to keep your house safe, healthy and free of water damage.
