Service Overview
What is Asbestos?

Asbestos is a naturally occurring mineral composed of microscopic fibers that were widely used in construction and manufacturing due to their heat resistance, strength, and insulating properties. While its useful properties led to widespread adoption, particularly in buildings constructed before the 1980s, the long-term health hazards associated with asbestos exposure gradually became apparent. Decades of research linked inhaled asbestos fibers to severe respiratory diseases, including lung cancer and mesothelioma. Federal regulations, primarily through the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), now strictly control asbestos use, handling, and disposal. The Clean Air Act, the Toxic Substances Control Act (TSCA), and OSHA's asbestos standards are key federal laws aimed at minimizing asbestos exposure and protecting public health.
Dangers of Asbestos
Asbestos poses a severe threat to human health, particularly when its microscopic fibers are inhaled. These fibers can become lodged deep within the lungs, causing inflammation and scarring that may lead to debilitating and often fatal diseases, such as asbestosis, lung cancer, and mesothelioma. These conditions can take decades to develop, making early exposure particularly insidious. Beyond the direct health risks to inhabitants, undiscovered or disturbed asbestos-containing materials can contaminate a property, leading to costly remediation efforts and potential legal liabilities. In New York City, failing to properly manage asbestos can also result in significant fines and violations from the Department of Housing Preservation and Development (HPD).At Cornerstone Testing Solutions, we specialize in comprehensive, independent asbestos surveys and specialized air monitoring. To protect your occupants and maintain strict alignment with NYC DEP and HPD guidelines, we provide unbiased environmental reporting and seamlessly coordinate with our network of trusted, licensed abatement contractors if material removal or encapsulation is required.


What We Test

Insulation
(Attic, pipe, spray-on)
Our Approach
1. Our inspectors systematically evaluate structural insulation for mechanical degradation, safely extracting bulk physical samples from pipe wrapping, attics, and spray-on materials.
2. Field teams comprehensively survey hidden crawlspaces and utility chases to meticulously identify and document suspected friable matrix layers.
3. Following chain-of-custody protocols, we issue a certified NVLAP laboratory analysis report detailing precise asbestos percentage composition.
Flooring/Wall/Ceiling Materials:
(Tiles, plaster, compounds, textured surfaces)
Our Approach
1. We cross-examine multi-layered surfaces, mapping out historical construction materials including vinyl floor tiles, plaster matrices, joint compounds, and textured skim coats.
2. Technicians execute clean core extractions on complex substrates, ensuring composite layers are fully captured for specialized analysis.
3. Once laboratory diagnostic screening concludes, we provide an authoritative data report establishing asbestos presence, material type, and classification.

Exterior Materials
(Roofing, siding, caulking)
Our Approach
1. We conduct rigorous exterior inspections across property envelopes, isolating weathered roofing felts, structural siding shingles, and caulking compounds.
2. Our team deploys safe cutting protocols to isolate structural surface samples without introducing airborne fibers to the environment.
3. You receive a detailed structural asset report outlining exterior liabilities and regulatory compliance pathways.

Heating System Components
(Furnace and Ducts)
Our Approach
1. We run thorough safety diagnostics across furnace insulation blankets, boiler breeches, and internal ventilation duct gaskets.
2. Field specialists carefully isolate and sample vintage thermal system insulation (TSI) while strictly keeping surrounding mechanical zones stabilized.
3. We follow up with a technical engineering breakdown, detailing component conditions and required regulatory handling steps.

When asbestos-containing materials (ACMs) are identified on your property, flawless project execution is mandatory. While we remain your independent testing authority to prevent any conflict of interest, we directly oversee and coordinate with licensed asbestos abatement professionals. We manage the technical project scope and execute rigorous post-abatement visual inspections and air clearance monitoring, delivering the definitive legal documentation needed to prove your building is safe for lawful re-occupancy.
