How can I prevent mold in a new home?

Question

I'm considering buying a new home that has not yet been built in Austin TX, but I heard mold was a huge problem there. How can I prevent mold or take preemptive measures..?

Answer 1

if mold is a problem its because the home was not built correctly for the climate / area. moisture has to be trapped consistantlly and unable to completely dry to create the ideal mold growing medium. building materials used can make a difference as well. examples would be mold resistant dry wall, shingles, paints, insulation (treated mold resistant blown cellulose is the best) even the lumber can be treated. in my opinion, the best way to prevent mold is with proper ventilation in the right places along with proper waterproofing to keep moisture out. mold problems usually arise when the builder cuts corners to save a buck. venting your bathroom fan into your unvented attic is a big no no but i see it all the time. give me a shout if you have you still have questions.

Answer 2

Molds need moisture to thrive and survive in most cases. Of course, a new house contains plenty of moisture until it has had sufficient time to 'dry out' completely. (Wallboard compounds, paints, wood all contain moisture) You can only watch for evidence of molds, test for them, and remediate.

The previous posters have solid advice as well. Since mold isn't an issue in my area, we are not thoroughly familiar with all the mold resistant materials available. Insure that they are used, as well as proper ventilation provided throughout the structure. Moisture is the real culprit for mold. Anything you can do to control moisture is a step in the correct direction.

Cleaning with a mild bleach solution kills mold spores, so it is your main method of prevention.

Proper ventilation helps, but it is humid there and you will never get things completely dry.

Seal any grout in kitchens and bathrooms and use mold resistant paint. Kelly Moore sells one. I am sure others do too, I just buy mine there.
