Mold Risk Reduction with Proper Ventilation

New homes are focused on sealing the inside from the outside world, but this is only a good option to a certain point. Sure, it is good to limit access into the home to bugs, dust, and other pests, but proper ventilation is what keeps a home from becoming an illness incubator. One of the ways lack of ventilation can become harmful to the health of its inhabitants is through mold growth.

A sealed home is susceptible to moisture in the bathroom, kitchen, or any other place that water happens to be used. Moisture from a small home’s bathroom may build up in a nearby bedroom, or boiling water can add moisture to an entire residence. Sometimes, this is great if your house is too dry, but it isn’t good to have that moisture stick around.

Mold likes stagnancy, and home without proper ventilation is the perfect location for mold to spread. Mold also likes moisture, and moisture won’t escape if there is nowhere for it to go.

It may seem counterintuitive, but the outside needs to come to the inside of your home, at least a little bit. This is very important for attics, where moisture combined with rising heat, creates the perfect environment for mold. And it is important for all areas of the home, as moisture can happen for many different reasons.

5 Ways to Ensure Proper Ventilation

1. Bathroom fan

A bathroom fan is essential to reduce moisture from the steam in the bathroom from warm showers and baths, but bathrooms have moisture from sinks and toilets too. A good bathroom fan will vent to the outside, not to the attic, and it will let moisture escape to the outside and prevent conditions conducive to mold.

2. Seal the rest of the area

New homes being sealed is not a bad thing as long as there is proper ventilation. In fact, areas not responsible for ventilation should be sealed, so ventilation works optimally.

3. Kitchen fan:

Like bathroom fans, kitchen fans should be vented to the outdoors. This means the hood above your stove should be connected to a vent outside. Sometimes, hoods have a simple fan that is not vented to anything, which defeats the purpose.

4. Crawl space vents:

Your crawl space is a place that will attract a lot of moisture if not ventilated, especially if you don’t have a cement slab foundation. Make sure it is vented, as this space is not one that is often checked for moisture build-up until a mold infestation has already taken hold.

5. Attic vents

Those attic vents in the gables of your home, or below the peaks of your roof, are actually doing quite a bit to eliminate mold via ventilation. If you don’t have gable vents, make sure your attic has a suitable alternative.
