Mold in a closed house: what to check every month

Why mold is a closed home's silent enemy

A closed home is a home without air exchange. Relative humidity rises, cold surfaces create condensation, and within weeks mold can take hold on walls, furniture, fabrics, and systems.

Keeping relative humidity below 60% is the critical threshold.

Essential monthly checks

• ✓Measure relative humidity in 2-3 rooms (target: below 60%)
• ✓Check for condensation on windows and cold surfaces
• ✓Inspect behind furniture against external walls
• ✓Open windows for controlled ventilation
• ✓Check drains for stagnant water
• ✓Verify no visible leaks or infiltration signs
• ✓Check basements and utility rooms
