Why North Park properties come to us for air quality testing
North Park, Golden Hill, South Park and downtown San Diego are full of pre-1940 bungalows with plaster and layered lead paint, while Clairemont, Chula Vista, El Cajon, Oceanside, Escondido and Vista were built out from 1950 to 1978 with acoustic ceilings and vinyl-asbestos flooring.
Marine-layer humidity on the coast, slab construction and swamp-cooled inland valleys mean leaks dry slowly indoors while inland homes run sealed for months.

The steps
How a North Park sampling visit runs
01
Tell us what you're about to disturb
Call, text a photo, or fill out the form. We identify the suspect materials, estimate the sample count, and lock in your flat price before anyone is dispatched.
02
A certified inspector collects the samples safely
Each distinct material is wetted down, a coin-sized piece is cut, sealed, labeled and logged under chain of custody. The mark left behind is smaller than a light-switch plate, and the space is left clean.
03
An accredited lab runs the PLM analysis
Samples are examined by Polarized Light Microscopy with dispersion staining — the EPA-recognized method for bulk building materials — with point counting available for borderline results.
04
You get a written report within 24 hours
A PDF lists every sample location, the analytical method, the fiber type detected and the reported percentage.
Independence
A company should not test the material it hopes to remove.
We collect and test material. ClearGuard does not sell removal work, keeping the finding independent. An abatement crew offering a "free inspection" is running a sales call with a lab form attached. We only sell the test, so a clean result and a positive result pay us exactly the same.
- No removal bids, no upsell, no referral kickback
- Every sample goes to an independent, accredited laboratory
- You get material names and percentages, not a vague pass or fail
- If a result is positive, we point you to licensed local abatement crews and exit the job
