Is there asbestos hiding in your home?
Homes built before 1980 often contain asbestos in materials you walk on, look up at, and live around every day. We collect samples and send them to a certified lab so you get results you can act on.
Why Asbestos Testing Matters
The Risk Era
Asbestos was widely used in building materials through the late 1970s. Homes, schools, and commercial buildings built before 1980 are most likely to contain it.
It’s the Disturbance That’s Dangerous
Asbestos that remains intact and undisturbed generally poses a lower risk. Renovation, demolition, or deterioration can release fibers into the air where they can be inhaled.
Serious Health Consequences
Inhaled asbestos fibers are linked to mesothelioma, asbestosis, and lung cancer. Because these diseases develop over decades, early awareness is critical.
Know Before You Renovate or Sell
Contractors must know before they cut, sand, or tear out materials. Sellers have a legal obligation to disclose known hazards. Testing gives you the facts first.
Where Asbestos Is Commonly Found
Asbestos was added to dozens of building products because of its heat resistance and durability. In older homes, it can turn up in places you might not expect.
Popcorn Ceilings
Spray-applied textured ceilings were one of the most common uses. Scraping or painting over them can release fibers.
Vinyl Floor Tiles & Backing
Nine-inch and twelve-inch vinyl floor tiles, as well as the adhesive used to install them, frequently contained asbestos through the 1970s.
Pipe & Duct Insulation
Asbestos was commonly wrapped around pipes and HVAC ducts for its heat-resistant properties. Deteriorating wrap is a direct inhalation risk.
Attic & Wall Insulation
Vermiculite insulation, common in older attics, may be contaminated with naturally occurring asbestos. Some blown-in insulation products are also suspect.
Drywall Joint Compound
Patching and finishing compounds used through the late 1970s often contained asbestos. Sanding these surfaces is particularly hazardous.
Roof Shingles & Siding
Asbestos cement was used in roofing shingles, corrugated panels, and exterior siding products. Damage or weathering can expose fibers.
How the Testing Process Works
On-Site Sample Collection
A Bent Nail inspector visits your home and collects small material samples from suspect areas, following safe handling procedures to minimize any fiber release during collection. You identify the areas of concern, or we assess based on the home’s age and construction type.
Certified Lab Analysis
Samples are submitted to a certified third-party laboratory for analysis using Polarized Light Microscopy (PLM), the EPA-recommended method for bulk material testing. The lab is accredited and follows EPA protocols.
Written Lab Report
You receive a written lab report identifying whether asbestos-containing materials (ACM) are present, the type of asbestos fiber if detected, and the percentage by weight. There’s no guessing – the data is specific to the materials sampled in your home.
Guidance on Next Steps
We walk you through the results. If asbestos is found, we explain what that means for your situation – whether it’s renovation planning, a real estate transaction, or a general safety evaluation – and what type of professional to call next.
Understanding Your Results
No Asbestos Detected
The sampled materials do not contain asbestos at regulated concentrations. You can proceed with confidence, and this documentation is valuable for disclosures or permit work.
Asbestos Detected
The lab report will identify the fiber type and concentration. If the material is in good condition and undisturbed, it may be safe to leave in place. If it is deteriorating or you plan to disturb it, a licensed asbestos abatement contractor should be engaged before any work begins.
The U.S. Environmental Protection Agency is the authoritative source for asbestos health guidance, regulations, and the latest regulatory actions, including the 2024 final rule banning ongoing uses of chrysotile asbestos. We recommend reviewing the EPA Asbestos resource page for information on protecting your family, finding licensed professionals, and understanding your rights as a homeowner or building owner.
Frequently Asked Questions
Not necessarily, but the probability is significant enough to warrant testing before any renovation work. Asbestos use was widespread in certain product categories, so older homes carry meaningfully higher risk than homes built after the late 1970s.
No. A standard home inspection is a visual assessment of the home’s major systems and components. Asbestos testing is a separate add-on service that involves physical sample collection and certified lab analysis. It can be added to any inspection or scheduled as a standalone service.
Not automatically. Asbestos that is in good condition and not disturbed generally does not release fibers into the air. The risk rises when materials are deteriorating, damaged, or being cut, sanded, or demolished. If you’re concerned, testing lets you know exactly what you’re dealing with.
No. Testing and abatement are different services performed by different specialists. We handle the testing and documentation. If removal or encapsulation is needed, we’ll advise you to hire a licensed asbestos abatement contractor. This separation ensures you receive an objective, unbiased assessment.
Turnaround time depends on the lab, but standard results are typically available within two to five business days after samples are received. Rush processing is available when time is a factor, such as a pending real estate closing.
Pricing depends on the number of samples collected. Each sample from a different material or location is tested separately. Contact us or schedule online for a quote based on your specific situation.
