From call to certified report
One visit, an accredited lab, and a document your contractor, escrow, or the AQMD can act on. Here's the whole process.
Tell us what’s planned
Share the property address, construction scope, approximate building age, affected rooms, and which materials may be disturbed.
We identify suspect materials
The survey reviews the materials affected by the project, including ceiling textures, drywall systems, flooring, adhesives, insulation, stucco, roofing, and utility components.
We collect and document samples
Samples are photographed, labeled by material and location, and submitted to the laboratory under documented chain of custody.
You receive certified findings
The final survey documents sampled materials, locations, laboratory results, positive and negative findings, and the scope needed for project planning.
When asbestos testing is required in Los Angeles
South Coast AQMD Rule 1403 generally requires a prior asbestos survey by a Cal/OSHA Certified Asbestos Consultant before demolition and before covered renovation work that may disturb suspect building materials.
For demolition, the survey must thoroughly evaluate the structure and relevant construction materials. For renovation, the survey can be limited to materials affected by the planned work.
A narrow exemption may apply when the legal owner and permanent resident of a single-unit house personally performs the renovation without hiring or receiving help from anyone else. Project-specific survey, notification, and permit requirements should be confirmed before work begins.
✓⃝ Before demolition: A comprehensive asbestos survey of the structure and relevant materials is required.
✓⃝ Before renovation: The survey evaluates affected materials that may be cut, sanded, drilled, removed, or otherwise disturbed.
✓⃝ After testing: The survey documents both positive and negative materials and helps determine whether notification or abatement is required.
Certified expertise behind every asbestos survey
Every formal survey should connect the site inspection, representative sampling, accredited laboratory analysis, and final certified report.

Common asbestos materials found in LA homes
If your property was built before 1980, these are the materials most commonly tested for asbestos in Los Angeles homes. Testing helps confirm what's present before renovation, repair, or removal decisions are made.
Ceilings & walls
Textured finishes and older wall systems are among the most common places asbestos may be found in pre-1980
Los Angeles homes.
COMMON MATERIALS
✓⃝ Acoustic "popcorn" ceilings
✓⃝ Drywall joint compound
✓⃝ Plaster & lath systems
-
Textured coatings
Floors
Older resilient flooring systems often contain asbestos in the tile, backing, or adhesive layer underneath the visible surface.
COMMON MATERIALS
✓⃝ Sheet vinyl & linoleum
✓⃝ 9x9" and 12×12" tile
✓⃝ Black flooring mastic
-
Carpet underlay adhesives
Heating & systems
Mechanical systems and utility materials can contain asbestos insulation and
heat-resistant components that should be tested before disturbance.
COMMON MATERIALS
✓⃝ HVAC duct wrap
✓⃝ Transite flues & pipes
✓⃝ Pipe & boiler insulation
-
Furnace gaskets
Exterior
Exterior building products may contain asbestos, especially in older siding, roofing, and weather-resistant materials.
COMMON MATERIALS
✓⃝ Stucco
✓⃝ Roofing felt & shingles
✓⃝ Cement siding
-
Window glazing compound

What your home's age predicts
Los Angeles was built in waves: craftsman neighborhoods in the 1920s, tract booms after the war, condo towers through the '70s. Building age helps narrow the list of suspect materials, but it cannot confirm asbestos. Original construction layers and later renovations can produce very different results, even in neighboring properties built in the same year.
✓⃝ Pre-1950: Plaster-and-lath systems, older pipe or duct insulation, roofing products, and multiple layers of original flooring may require evaluation.
✓⃝ 1950s–1970s: Acoustic ceiling texture, drywall joint compound, resilient flooring, mastics, duct wrap, and exterior products are commonly encountered.
✓⃝ Late 1970s and later: Product phase-outs occurred over time, and older inventory continued to be installed. Construction date alone does not rule asbestos in or out.
✓⃝ Renovated homes: New finishes may cover older flooring, adhesive, plaster, texture, or insulation that remains in place underneath.
Independent asbestos testing without an abatement sales pitch
Same samples. Different incentives.
Interlink tests and documents building materials. We do not perform asbestos removal, operate an abatement crew, or accept contractor referral fees.
That means a negative result stays negative, and a positive result becomes a precise, contractor-neutral scope, not a sales opportunity.

Water-damage repairs can uncover suspect asbestos materials
A stained ceiling, damaged flooring, or deteriorated plaster may require asbestos testing before repairs begin. If the moisture source has not been identified, Interlink can coordinate the inspection scope so both the water damage and affected building materials are documented before anything is cut or removed.
Asbestos Testing Los Angeles FAQs
South Coast AQMD Rule 1403 generally requires a prior asbestos survey before demolition and before covered renovation work that may disturb suspect building materials. For renovation, the survey may be limited to materials affected by the project.
A narrow exemption may apply when the legal owner and permanent resident of a single-unit house personally completes the renovation without help from a contractor, laborer, friend, or family member. Requirements should be confirmed for the specific property, project scope, and permitting jurisdiction.
Age is the best predictor: ceilings installed through the 1970s often test positive, and later ones sometimes do; materials already on shelves kept being installed after the bans. The only real answer is a sample; guessing in either direction gets expensive.
Pre-renovation surveys start around $450, with samples at $95 each, including accredited lab analysis. A typical single-room project needs 3–6 samples. Demolition and commercial surveys are quoted by scope. Exact number before we schedule; never a removal quote attached.
Standard PLM lab results in 24–48 hours; same-day rush is available when escrow or a crew on standby demands it.
For many limited bulk-sampling visits, occupants can remain elsewhere in the property while controlled samples are collected. The appropriate precautions depend on the material, its condition, the sampling area, and the number of samples. Your inspector should explain any access restrictions before the appointment.
A mail-in kit may provide a laboratory result for the specific material fragment submitted, but it does not document the property, establish representative sample locations, evaluate affected materials, or produce a certified asbestos survey.
When a formal survey is required for demolition, covered renovation work, regulatory documentation, or project planning, use a qualified asbestos professional and confirm the applicable CAC requirements.
You get exact locations, quantities, and lab certificates, the scope a licensed abatement contractor bids against. We don't do removal and don't refer for a fee, so the abatement market has to compete for your job on price.
Yes, when included in the project scope. Post-abatement verification may include a visual inspection, air sampling, or other specified clearance procedures. The final documentation states whether the applicable clearance criteria were met.
Intact, undisturbed material is generally a manage-in-place situation, not an emergency. The risk is disturbance, which is why testing belongs before the remodel, not after the demo crew has found something.
Yes, offices, retail, and multifamily across LA, including demolition-scope surveys and tenant-improvement projects.
That's the most common way we're used: limited surveys scheduled inside inspection contingency windows, with rush lab options when the calendar is tight.
