Not White Paint

At first glance, the home inspector thought the bottom of the subfloor had been painted white.white mold sacramento home inspection

Upon closer inspection, the inspector concluded it was a bio-growth. An inspector (unless they’re a certified industrial hygienist) shouldn’t say ‘mold’, as doing so makes them the expert in a court of law.

If there’s a bio-growth growing on crawlspace surfaces, there’s a good chance there are issues with inadequate or poor ventilation; leaking toilets, negative grade; no drainage system; downspouts discharging next to the foundation; over-irrigation; leaking water supply or drain pipes; swimming pool leaks; high water table all of which can contribute to high humidity conditions under a house.

Mold spores and wood moisture content above 28% are required for mold to start developing on wood. Molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees; but indoors, mold growth should be avoided.

The fix: It’s all about controlling the level of moisture in the crawlspace.

The inspectors at Pacific Coast Inspections may not be Industrial Hygienists, but are quite knowledgeable about discussing their observations in a low key manner and making recommendations for further review.
