Three ways to order a test
First-time clients usually use the address tool because it shows the price band before anything is booked. Repeat clients — property managers, restoration crews, general contractors — skip the form entirely and text or email the same six lines. Either way $50 off asbestos & mold applies and the tech is assigned from the property ZIP.
Enter the property address, pick the material and the turnaround, see your price band, then confirm with name, phone and email. Best for a first order or when you want the number in writing first.
See my price and orderText the six lines below to (510) 901-5743. Dispatch replies with the confirmed price, the tech window, and a secure card link — usually within minutes during business hours.
Email the same lines to orders@precisionenvironmentaltesting.com. It is read automatically, so a purchase order or work-order thread can be forwarded straight in — CC your adjuster or PM and everyone stays on the same record.
Missing fields are the only thing that slows a dispatch down. Include these and the order is assigned on the first reply.

What happens to your sample
Identified on site
The inspector separates materials by type and photographs every location before anything is touched.
Collected under containment
Samples are wetted, cut small, sealed in labelled containers and the spot is patched before the inspector leaves.
Logged and transferred
Each container is entered on a chain-of-custody form that travels with the sample to the laboratory.
Analyzed and reported
Every sample is read by an independent accredited laboratory under a documented chain of custody. You receive percentages, material names and sample locations in a written report.
Independence
Testing is all we do. We never quote, sell or perform removal — our only job is an honest result. A free test offered by an abatement contractor is a sales call with a lab report attached. Our only product is the result, so a negative answer costs us nothing and a positive answer earns us nothing extra.
Asbestos knowledge
A negative result (no asbestos detected) means you can demolish, scrape or remodel that material with normal construction practice. A positive result means the material must be removed by a licensed abatement contractor, encapsulated, or left undisturbed — it does not mean your home is unsafe to live in.
Positive does not automatically mean expensive. Many owners change the scope instead: floating a new floor over old tile, drywalling over a textured ceiling, or shifting a wall opening a few feet.
If removal is the right call, your report becomes the scope document abatement contractors bid from, which usually gets you a tighter and more honest price than a vague verbal description.
Because we only test — we do not sell abatement — there is no incentive on our side for a result to come back positive. That independence is exactly what buyers, landlords and permit reviewers want to see.
state treats pre-1981 textured ceilings and many older building materials as presumed asbestos-containing unless a lab report proves otherwise, and state and federal rules require a survey before most renovation or demolition work on regulated structures.
OSHA and your state asbestos program rules require employers to determine the presence of asbestos before disturbing suspect material, which is why contractors ask you for a report before they will start.
Federal NESHAP rules, enforced locally by the your state environmental agency and the state Department of State Health Services, require a thorough asbestos survey before demolition and many renovations, plus advance notification when thresholds are met.
Permit counters increasingly ask for the lab report as an attachment. Having it in hand before you apply prevents a stop-work order and the two-week scramble that follows one.
Landlords, property managers and sellers also use testing defensively: a dated report showing what was tested and when is strong documentation if a tenant or buyer raises the question later.
A mail-in home kit can tell you what a chip of material contains, but it has no chain of custody and no inspector attestation, so contractors, abatement firms and permit offices usually will not accept it.
The bigger problem is collection. Dry-scraping your own popcorn ceiling to grab a sample is precisely the activity that releases fibers — people frequently contaminate a room trying to save a couple hundred dollars.
A certified inspection wets the material, contains the area, documents the sample location, and produces a report with the inspector and lab identified. That is the version that holds up.
Price is driven by the number of homogeneous materials sampled, the size and access of the building, and turnaround speed. Precision Environmental Testing gives you $50 off asbestos & mold for single-material testing with 24-hour certified results, with multi-material and pre-demolition scopes quoted before sampling starts.
Most local providers quote a multi-day turnaround, then bill a rush surcharge when you need the answer sooner. Our position is simple: speed is the standard, your quote is confirmed on the phone before anyone visits, and $50 off asbestos & mold comes off the booking.
Every distinct material is its own sample. A kitchen remodel touching ceiling texture, floor tile and mastic is three materials, not one — which is why a walkthrough or a few phone photos gets you an accurate number before anyone drives out.
Pre-demolition surveys on whole structures are scoped separately because regulations require systematic coverage of every suspect material, not a spot check.
The process
01
Call, text a photo, or send the form. We identify the suspect materials, the likely number of samples, and confirm the flat price before anyone is dispatched.
02
Each homogeneous material is wetted, cut in a coin-sized piece, sealed, labeled and logged under chain of custody. The patch is smaller than a light-switch plate and the area is left clean.
03
Samples are analyzed by Polarized Light Microscopy with dispersion staining — the EPA method for bulk building materials — with point counting available for borderline matrices.
04
You receive a PDF listing every sample location, the asbestos type detected and the percentage, ready to hand to a contractor, abatement firm or permit desk.
Your deliverable
You receive a PDF you can forward directly to your contractor, abatement bidder, permit reviewer, landlord, insurer or buyer's agent. It is written to be accepted, not to be explained.

FAQ
Yes. Federal NESHAP rules enforced by state and federal regulators require a thorough asbestos survey before demolition of regulated structures, along with advance notification to the regulating agency.
No, but textured ceilings sprayed before 1981 are presumed to contain asbestos in most states until a lab report proves otherwise. Testing a single coin-sized sample settles it in 24 hours.
Intact, undisturbed asbestos material generally poses little risk. The hazard arises when the material is sanded, scraped, drilled, cut or demolished and microscopic fibers become airborne, which is why testing happens before work rather than after.
Very little. Each homogeneous material needs one coin-sized sample, wetted before collection and sealed in a labeled bag. The resulting patch is typically smaller than a light-switch plate.
One per homogeneous material — meaning each distinct material by color, texture and installation era. A kitchen remodel touching ceiling texture, floor tile and mastic requires three samples, not one.
Store kits can produce a lab number, but they lack chain of custody and an inspector attestation, so contractors, abatement firms and permit offices commonly reject them. Self-collection also risks releasing fibers during sampling.
You have three compliant options: licensed abatement, encapsulation or covering the material in place, or leaving it undisturbed and changing your project scope. Your report becomes the scope document abatement contractors bid from.
Removal of regulated quantities must be performed by a your state asbestos program-licensed asbestos abatement contractor. Homeowners have limited allowances for their own single-family residence, but disposal and notification rules still apply.
Yes. Landlords, property managers and commercial owners routinely order testing before tenant turnovers, capital work and demolition, and the same flat pricing and 24-hour turnaround apply.
No, and that is deliberate. We only test, so the result carries no financial incentive and stays independent — which is exactly what buyers, permit reviewers and tenants want to see.
