Can you have a mold problem is your brand new house? Absolutely, in some cases new houses can have a more significant mold problem than an old house. If proper construction protocols are not followed during construction mold can contaminate the house without you knowing about it.
I came across this news story that illustrates how serious the problem can be.
How do you know if your new house has a hidden mold problem potentially creating a health problem? Have the air tested for mold. See Mold Testing for more information. Also see the previous post on this blog on some of the reasons new houses have mold problems.
