Asbestos Testing in Simi Valley, CA
Most of Simi Valley was built in the 1960s and 70s — the exact years asbestos went into nearly everything: popcorn ceilings, floor tiles, mastic, duct wrap, stucco, and plaster. Left alone, it’s generally not a hazard. It becomes one the day you scrape a ceiling, pull up flooring, or open a wall. Testing before the project is the smartest call a homeowner here can make.

One visit either clears your project to proceed — or saves you from the most expensive dust you’ll ever create.
It’s the law more often than people think
In Ventura County, VCAPCD Rule 62.7 governs asbestos in demolition and renovation. A survey is required before demolition permits are issued, and projects disturbing asbestos-containing material carry notification requirements to the district — with waiting periods and fees for larger jobs. Homeowners find this out at the permit counter; smart ones find it out from us first.
DIY disturbance is the expensive mistake
Scraping a popcorn ceiling that tests positive doesn’t just risk your family’s health — it can turn a weekend project into a professional decontamination. The test that would have cost less than your dinner out is the cheapest insurance in home improvement.
Certified means certified
California requires asbestos consulting work to be performed under Cal/OSHA-certified professionals. Every survey we deliver is CAC-led, with samples analyzed by accredited laboratories — reports your contractor, your permit office, and your buyer’s agent will accept without a fight.
Independence matters
Testing companies that also sell removal have an incentive problem. We test, we report, we explain — and if abatement is needed, you choose who does it with a clean report in your hand.
Simi Valley’s Homes Were Built in the Asbestos Era
The numbers tell the story: Simi Valley grew from a quiet valley town to a city of over 100,000 almost entirely between 1960 and 1980 — the peak decades of asbestos construction products.
Popcorn ceilings from that era commonly contain 1–10% asbestos. The 9×9 floor tile hiding under carpets across Wood Ranch, Santa Susana, and central Simi is a textbook suspect. Even Simi Valley High School has had asbestos ceiling materials professionally removed. If your home predates 1980 and you’re planning a kitchen remodel, flooring replacement, ceiling scrape, ADU conversion, or earthquake retrofit — test first.
We serve Simi Valley, Moorpark, Thousand Oaks, Camarillo, Fillmore, Santa Paula, Ventura, and the neighboring west San Fernando Valley (Chatsworth, West Hills — where LA County’s separate SCAQMD Rule 1403 applies; we handle both districts’ requirements).
