In the Central Valley, mold isn’t just a seasonal nuisance—it’s a year-round threat hiding behind drywall, under sinks, and inside HVAC systems. With our mix of foggy mornings, leaky roofs, and tightly sealed homes, moisture can linger long enough to invite unwanted fungal guests.

Here’s how to spot it, stop it, and stay ahead of it:

Know the Signs

• Musty odors even when everything looks clean
• Discoloration on walls, ceilings, or window sills—especially green, black, or white patches
• Condensation on windows or pipes
• Persistent allergy symptoms like sneezing, coughing, or itchy eyes indoors

Prevention Starts with Ventilation

• Run bathroom and kitchen fans during and after use
• Open windows when weather permits to increase airflow
• Use a dehumidifier in basements or poorly ventilated rooms

Stop Moisture at the Source

• Fix leaky roofs, pipes, and appliances immediately
• Check for standing water in crawl spaces or under sinks
• Seal gaps around windows and doors to prevent rain intrusion

Clean Smart, Not Just Hard

• Scrub small mold patches with soap and water, not bleach (which doesn’t penetrate porous surfaces)
• Remove and replace moldy drywall, carpet, or insulation
• Never paint over mold—it just traps the problem

Know Your Rights

If you're renting and mold makes your unit uninhabitable, California law requires landlords to remediate it promptly under SB 655. Document everything and report issues in writing.
