What is the very first thing to do for mold?

Do NOT disturb the affected area — moving things spreads spores throughout the home.

Should I call insurance or restoration first?

Call restoration first. Emergency mitigation work is covered without prior adjuster approval on virtually every standard policy — it falls under the homeowner's duty to prevent further damage. The adjuster gets assigned in parallel.

How fast can Catalyst arrive?

For active emergencies in our core service region we target on-site arrival within 1–2 hours. Extended areas are 2–3 hours typical.

What does emergency mitigation typically cost?

Emergency mitigation is almost always covered by your homeowners insurance when caused by a sudden and accidental event. We bill direct to most major carriers and document everything the carrier needs to settle.

Do these, in order.

These are the steps we tell people in the first 5 minutes of a call. Safety first, then documentation, then the phone.

Step 1
Do NOT disturb the affected area — moving things spreads spores throughout the home.
Step 2
Do NOT clean with household bleach. It does not kill the colony in porous surfaces and complicates remediation.
Step 3
Photograph the visible growth from multiple angles before any further action.
Step 4
Identify the moisture source if you can see one — without addressing the moisture, mold returns.
Step 5
Call us for an IICRC S520-aligned assessment. Some scopes are smaller than they look; some are larger.

About this service

Mold Remediation

Mold spreads silently behind walls and under flooring. Our IICRC-aligned remediation protocol contains the spread, removes affected materials, HEPA-cleans the environment, and verifies clearance with post-remediation testing.
