How mold evaluations work, what drives moisture in Minnesota homes, and why finding the source matters. This guide is written for Minnesota homes by Closer Look Inspectors.
Mold is a moisture story
Mold growth follows water — basement dampness, roof and plumbing leaks, condensation, high humidity, and ventilation deficiencies. The signs are musty odors, staining, visible growth, window condensation, and a history of water damage.
How we evaluate it
We pair a visual inspection with infrared and moisture metering, available as add-ons, to locate active moisture and its source, and recommend laboratory sampling when warranted for objective results. Finding the water is the real fix; mold returns until the source is corrected.
Minnesota moisture drivers
Negative grading and short downspouts, below-grade humidity, freeze-thaw foundation cracks, and the occasional plumbing leak are the usual culprits here.
