Montgomery's average summer humidity sits north of 75%. Combined with mild winters, that creates a year-round mold-friendly environment in any home with poor ventilation.
The four highest-risk spots in a Montgomery home: behind washing machines on exterior walls, under bathroom sinks, in attic spaces with blocked soffit vents, and inside HVAC return chases.
The cheapest preventive fixes: a $35 hygrometer in your living room (target under 55%), a $180 dehumidifier in any room that runs above that, exhaust fans in every bath that vent OUTSIDE the attic, and a yearly attic inspection.
If you already see mold, do NOT use bleach on porous surfaces — it kills surface growth but leaves the roots. A professional remediation by a verified Montgomery pro is the right call. Find one through HandyMandyMan.
