American homeowners facing flood damage now have new resources to help them tackle one of the most common and dangerous aftermath problems: mold growth. HearthDry, a home restoration guidance company, has announced the addition of certified mold mitigation guidance specifically designed for US homeowners dealing with water damage in their properties.
This announcement comes at a critical time. Hurricane season is in full swing, and flooding events across the country have left thousands of homes vulnerable to mold contamination. When water enters a home, mold can begin growing on wet surfaces within 24 to 48 hours, making quick action essential for protecting both property and health.
Why Mold After Flooding Is a Serious Concern
Flooding creates the perfect conditions for mold to thrive. Warm temperatures, standing water, and wet building materials like drywall, carpet, and wood provide everything mold spores need to multiply rapidly. Even after visible water is removed, moisture can remain trapped inside walls, under floors, and in insulation for weeks.

However, many flood-affected homeowners cannot return to their properties immediately, or they lack the knowledge and tools to properly assess the damage once they do.
What the New Guidance Covers
HearthDry's certified mold mitigation guidance aims to fill this knowledge gap. The resources provide homeowners with step-by-step instructions for:
- Assessing flood damage safely
- Identifying areas most likely to develop mold
- Understanding when professional remediation is needed
- Taking proper safety precautions during cleanup
- Documenting damage for insurance claims
The guidance emphasizes that homeowners should never attempt to clean large areas of mold growth themselves. The CDC recommends calling a professional if mold covers an area larger than about 10 square feet, or if mold has grown inside HVAC systems or after sewage backup.
Hidden Mold: The Invisible Threat
One of the biggest challenges homeowners face after flooding is detecting mold they cannot see. Mold often grows behind walls, under flooring, and in other hidden spaces where moisture collects. By the time visible mold appears or a musty odor becomes noticeable, the contamination may already be widespread.
Surface testing can help homeowners identify mold growth on materials throughout their home. Collecting samples from suspected areas and having them analyzed by an accredited laboratory gives homeowners clear answers about what they are dealing with.
Steps Homeowners Should Take After Flooding
Experts recommend the following actions for homeowners returning to flood-damaged properties:
- Document everything with photos and video before cleanup begins
- Remove standing water as quickly as possible using pumps or wet vacuums
- Increase air circulation by opening windows and using fans
- Remove wet materials that cannot be dried within 48 hours, including carpet, padding, and drywall
- Test surfaces in areas that were wet or show signs of damage
- Contact your insurance company promptly to report the damage
Homeowners should wear protective equipment including gloves, goggles, and an N95 respirator mask when entering flood-damaged areas or handling materials that may contain mold.
Frequently Asked Questions
How quickly does mold grow after a flood?
Mold can begin growing on wet surfaces within 24 to 48 hours after flooding occurs. This is why experts stress the importance of drying out homes as quickly as possible. Even if you cannot see mold, spores may already be colonizing damp materials inside walls and under floors.
Can I clean up mold myself or do I need a professional?
Small areas of mold, generally less than 10 square feet, can often be cleaned by homeowners using proper safety equipment. However, larger contaminations, mold in HVAC systems, or mold resulting from sewage backup should be handled by certified professionals. Testing surfaces first helps you understand the scope of the problem.
How do I know if there is mold I cannot see after flooding?
Hidden mold often reveals itself through musty odors, even when no visible growth is present. You may also notice allergy-like symptoms when in the affected area. Surface sampling from walls, floors, and other materials can detect mold growth that is not visible to the naked eye, giving you clear laboratory results about contamination in your home.
If your home has experienced flooding or water damage, testing is the first step toward understanding what you are dealing with. A MycoTest DIY Mold Test Kit lets you collect surface samples from anywhere in your home and send them to an accredited laboratory for analysis. You will receive clear results that tell you exactly what is growing in your home, so you can make informed decisions about cleanup and remediation.
