After a Leak or Flood: When to Get a Mold Inspection in San Francisco

Recently updated

Water damage doesn’t just disappear when things dry out. After a leak or flood in your San Francisco home or building, the risk of hidden mold skyrockets. A professional mold inspection is the safest way to ensure your property remains healthy—and compliant.

At Bay Area Mold Pros, we specialize in mold inspection and mold testing services across San Francisco, San Mateo, Santa Clara, Marin, Alameda, and Contra Costa counties. If your property recently experienced water intrusion, now is the time to act.

Why Mold Follows Water Damage

Even a small leak can create the perfect conditions for mold. Mold spores begin to grow on wet surfaces within 24 to 48 hours of exposure. If left unchecked, mold can spread behind walls, under floors, and inside HVAC systems—often without visible signs.

Common water sources that lead to mold include:

• Burst or leaking pipes
• Overflowing sinks or bathtubs
• Roof leaks
• Flooding from storms or broken appliances
• Condensation from poor ventilation

When Should You Schedule a Mold Inspection After Water Damage?

The best time to get a mold inspection is within 48–72 hours after you’ve contained the leak or flooding. This gives professionals a chance to detect early-stage mold growth before it spreads or becomes a health hazard.

You should also get a mold inspection if:

• Musty odors remain even after drying out the space
• Walls or ceilings show signs of bubbling, discoloration, or sagging
• Your family or tenants experience unexplained allergy or asthma symptoms
• Mold was previously removed but may have returned

What Happens During a Post-Leak Mold Inspection?

At Bay Area Mold Pros, we perform thorough inspections designed for water-damaged properties:

• Visual assessment of water-affected areas (walls, ceilings, floors, crawlspaces)
• Moisture mapping using infrared thermal imaging
• Air sampling to detect invisible airborne mold spores
• Swab testing for visible mold colonies

Our certified inspector provide a detailed report with lab-tested results, helping you take the right next steps—whether it’s remediation or simple monitoring.

Why It’s Risky to Wait

Waiting too long can allow mold to spread into hidden structural areas, creating:

• Expensive remediation costs
• Health risks for occupants (especially children, seniors, and those with respiratory issues)
• Insurance complications if mold is not addressed in a timely manner
• Possible violations of San Francisco’s habitability and housing health codes
