Mold Prevention for Conroe and Montgomery County Homes

Hold indoor humidity between 30 and 50 percent

A twenty dollar hygrometer tells you more about your mold risk than any inspection. Above 60 percent relative humidity, growth becomes likely on any organic surface, and Conroe outdoor air sits well above that most of the year.

The 48 hour rule

Any material wet longer than 48 hours should be treated as a mold risk. That includes a small under-sink leak nobody mentioned for a week.

Maintenance that prevents mold

Seasonal habits that eliminate most residential mold cases:

• Flush the AC condensate line with vinegar each spring
• Run bathroom exhaust fans 20 minutes after showers
• Check under sinks and behind toilets monthly
• Keep gutters and downspouts clear
• Grade soil away from the foundation
• Install a crawl space vapor barrier on pier-and-beam homes

When prevention has already failed

Visible growth larger than about ten square feet, a musty smell you cannot locate, or symptoms that improve when you leave the house all warrant professional assessment rather than surface cleaning.
