Your sample came back positive. What happens now.
A positive asbestos result is not an emergency and it is not a demolition order. Here is what the result actually means, what has to happen before anyone starts work, and what the finished job should leave you holding.
Most people who call us have just opened an email from a lab. The report has a percentage in it, the word chrysotile or amosite, and no explanation of what to do next. Usually the renovation has already stopped.
The first thing worth saying: a positive result is not an emergency. Asbestos in good condition, left alone, is not releasing fibres. What creates exposure is disturbing it — sanding, cutting, scraping, breaking it up. That is why the result arrived because work started, and why stopping was the right call.
What the result actually tells you
A lab result identifies the material and the percentage. It does not tell you how much there is, where else it is, or what removing it involves. Those are separate questions, and the answers change the job considerably.
In California, any material above one percent asbestos is regulated. Below that threshold it is not regulated as asbestos-containing material, though it may still carry handling requirements. A survey tells you the extent. A single positive sample tells you only that one sampled location is positive.
This matters because the most common material we find — popcorn ceiling texture, 9x9 floor tile, the black mastic underneath it, drywall joint compound — tends to appear throughout a house rather than in one room. One positive sample on a kitchen floor usually means the hallway is worth testing too.
What has to happen before anyone starts
Three things, in this order.
A survey or a protocol. For a small, visible, single-source problem, a walkthrough can sometimes be enough to scope from. For anything tied to an insurance claim, a property sale, or a regulated asbestos scope of any size, an independent survey comes first. It defines the work, and it is the thing the final clearance gets measured against. The party that writes the protocol should not be the party that does the removal.
Notification. Before regulated asbestos work begins, a notification is filed with the air district covering the property and a waiting period runs. In Los Angeles, Orange and the inland valleys that is South Coast AQMD under Rule 1403. San Diego County has its own district and its own rule, as does Ventura. The waiting period is fixed and it runs before mobilisation.
This is the single most common reason an abatement job starts later than the owner expected. It is not paperwork someone forgot — it is a scheduled interval, and it either gets built into the timeline or it delays everything downstream.
Containment. The work area is sealed and put under proper containment before removal starts, and material is kept wet to hold fibres down. For a single-room scope in a larger building you can often stay in the house. For whole-house work, you cannot. Anyone who will not tell you which of those you are looking at before the job starts is guessing.
Who clears the work
Not the contractor who did it. Independent third-party clearance is what makes the result defensible later, and the party clearing the work should never be the party that performed it. That is not a courtesy — it is the difference between a document that answers a question two years from now and one that does not.
If a contractor offers to clear their own work, that is worth noticing.
What you should be holding at the end
This is the part people do not think about until they need it, and by then it is too late to create.
When the job closes, you should have the survey or protocol, the filed notification, containment logs, photographs from before, during and after, waste manifests showing where the material went, and the independent clearance result.
That file is the point. Exposure on a regulated property does not end when the material leaves the site — it ends when someone can show how it left. During a sale, a tenant dispute, or an insurance claim, an owner holding that record is in a materially different position from an owner holding an invoice.
When the answer is that you do not need us
Sometimes it is. If the building went up after about 1985, a survey will very often come back negative, and we would rather say so on the phone than sell you a mobilisation. Newer housing across Santa Clarita, Moreno Valley, Temecula and the east side of Chula Vista falls into this category routinely.
If you have a result in front of you and you are not sure what it means, call and read it to us. That conversation is free and it is usually short.
Tell us what you are dealing with.
Tell us what was found, what work is planned and when the property needs to be ready. We will walk the site, define the scope and provide a written proposal with the work sequence, exclusions, schedule and price.
