What is the very first thing to do for biohazard?

Do not enter the affected area — biological material carries bloodborne pathogens that require PPE and containment to handle safely.

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 enter the affected area — biological material carries bloodborne pathogens that require PPE and containment to handle safely.
Step 2
If law enforcement is involved, wait for the scene to be formally released before any cleanup begins.
Step 3
Close the door to the area and shut off HVAC serving that room to limit cross-contamination.
Step 4
Keep children and pets well away from the affected area.
Step 5
Skip household cleaners — biological material requires regulated handling, certified disposal, and documentation. Call us first.
