In short

Mold remediation is the removal of mold-contaminated materials and the correction of the moisture that caused them. The EPA advises drying water-damaged materials within 24 to 48 hours to prevent mold; areas larger than about 10 square feet call for a professional.

How mold follows water damage

Mold spores are present in every home. They grow when a material stays wet: drywall behind a leaking supply line, carpet pad that was never fully dried, a cabinet base under a slow drip, a ceiling below a roof leak. The EPA's guidance is to dry water-damaged areas and items within 24 to 48 hours; after that, growth becomes likely.

In Huntington Beach, three situations produce most mold calls:

Hidden leaks

Under slabs, behind walls or under sinks in older tract homes, found only after weeks.

Water damage that was dried on the surface only

With wet pad, subfloor or wall cavities left behind.

Coastal humidity

In homes near the beach and the harbour, where poorly ventilated bathrooms and closets stay damp.

What you can handle and what you should not

The EPA says an area of mold smaller than about 10 square feet (roughly a 3-by-3-foot patch) can usually be cleaned by the homeowner: fix the water problem, wear gloves, goggles and an N-95 respirator, scrub hard surfaces with detergent and water, and dry them completely. Absorbent materials such as ceiling tiles and carpet that are moldy may need to be thrown away.

Call a professional when:

  • The area is larger than about 10 square feet.
  • Mold is inside walls, in the HVAC system, or under flooring.
  • The water was contaminated (sewage or flood water).
  • Anyone in the home has asthma, allergies or a weakened immune system.
What to have ready when you call
  • The address, including the zip code
  • What is wet: which rooms, floors, walls or ceilings
  • Where the water came from and when it started
  • Whether water is still coming in
  • Whether you have homeowners or renters insurance

What a mold remediation contractor will do

  1. Find the moisture source and confirm it is fixed; remediation without fixing the leak does not last.
  2. Assess the extent with moisture meters and inspection; some contractors or independent assessors also take air or surface samples.
  3. Contain the work area with plastic sheeting and negative air pressure, so spores do not spread through the house.
  4. Remove contaminated porous materials (drywall, insulation, carpet) and clean hard surfaces.
  5. Clean the air with HEPA filtration, then dry the area and document the work.

The industry standard is ANSI/IICRC S520 for professional mold remediation. California does not license mold assessors or remediators, according to the California Department of Public Health, but any demolition or rebuilding above $1,000 requires a CSLB-licensed contractor.

Cost and insurance

Mold remediation cost depends on how much material has to be removed and whether containment is needed; small, contained jobs cost far less than whole-room work. Many homeowners policies cover mold only when it results from a covered sudden water loss, and often cap mold at a sub-limit. Check the mold section of your policy before work starts. See also the water damage cost page.

Frequently asked questions

How quickly does mold grow after water damage?

The EPA advises drying water-damaged materials within 24 to 48 hours to prevent mold growth. Materials that stay wet longer are at high risk.

Is mold from water damage harmful?

Mold can cause allergic reactions and asthma symptoms in sensitive people, according to the EPA. People with respiratory conditions should stay out of affected areas.

Do I need a mold test before remediation?

Visible mold usually does not need testing to be removed. Testing helps when mold is suspected but not visible, or to confirm clearance after the work.

Does California license mold remediation companies?

California does not license mold assessors or remediators, per the California Department of Public Health. Ask for IICRC training (AMRT) and a CSLB license if walls or floors will be rebuilt.
