The property is not safe to reoccupy until it is done. Residue reactivates — people have been affected by it weeks after an incident, in a room that looked clean.

One thing overrides everything on this page: do not attempt any part of this yourself, and do not let a general cleaning company do it either. The protective equipment, the containment and the licensed disposal route exist because of a genuine bloodborne pathogen risk, and California requires a company doing this work to be registered with the state.

Signs to look for

Police deployment of chemical agents at the property
A fine powder residue on surfaces throughout
Eye and throat irritation on entering a room that looks clean
Symptoms returning when heating or hot water is used
A property that cannot be reoccupied or re-let

How the work is done

Keep the building unoccupied and the HVAC off until the work is complete
Remove soft furnishings and textiles that have absorbed the agent
Decontaminate the HVAC, which is the main distribution route
Verify before reoccupancy rather than relying on how it looks

In California specifically

California's Mediterranean on the coast, hot and dry inland climate and its housing stock — stucco ranch and bungalow, tile or composition roofs, slab in the south and raised crawlspace through the Bay Area and the north — decide what is worth doing first. California is also the one state where duct leakage is routinely tested: Title 24 requires a HERS-verified duct test on most furnace or air-conditioner changeouts, so a duct problem here often surfaces as a failed test rather than as a complaint.

Before the technician arrives

Four things worth doing — and the first one is usually the thing people get wrong.

Do not reoccupy the property, and keep children and anyone with asthma well away.
Do not run the HVAC. It distributes the residue through the whole building.
Do not attempt to clean it. Water and heat both reactivate it, so ordinary cleaning makes the exposure worse.
Ask the company whether they have done this specific work before. It is a specialism and not every restoration firm has.

How it works

Three steps, and you decide at the end of them.

1
You call and describe the problem

Tell us what you have noticed and where — the room, the smell, the noise, how long it has been going on. Give us your ZIP code and we will match you to a licensed company covering your area. There is no form to fill in.
2
A local company takes it from there

They discuss the problem with you directly, arrange a time to inspect, and agree the work and the price with you before anything starts. That conversation is between you and them.
3
You decide whether to go ahead

You are under no obligation. If the quote or the approach is not what you wanted, you are free to say no and call someone else.

Tear Gas and Chemical Residue — FAQs

Do I actually need Tear Gas and Chemical Residue done?

The property is not safe to reoccupy until it is done. Residue reactivates — people have been affected by it weeks after an incident, in a room that looked clean.

What does Tear Gas and Chemical Residue involve?

Decontaminating after police chemical agents. A genuine specialism: the residue is persistent, it reactivates, and ordinary cleaning spreads it.

What makes this different in California?

California's Mediterranean on the coast, hot and dry inland climate and its housing stock — stucco ranch and bungalow, tile or composition roofs, slab in the south and raised crawlspace through the Bay Area and the north — decide what is worth doing first. California is also the one state where duct leakage is routinely tested: Title 24 requires a HERS-verified duct test on most furnace or air-conditioner changeouts, so a duct problem here often surfaces as a failed test rather than as a complaint.

Are the companies licensed and insured?

Yes. We only pass calls to licensed, insured operators working in California, and you are welcome to ask to see a license number on arrival.

What does Tear Gas and Chemical Residue cost?

It depends on the property, the size of the system and what the inspection finds, so we do not publish a price — a figure quoted on a web page is not one the attending company has agreed to. You get a price before any work starts.
