Asbestos has been used in building materials, paper products, plastics, and other products. Exposure mainly occurs in indoor air where it may be released from these materials. Effects on the lung are a major health concern from asbestos, as chronic (long-term) exposure to asbestos in humans via inhalation can result in a lung disease termed asbestosis. Asbestosis is characterized by shortness of breath and cough and may lead to severe impairment of respiratory function. Cancer is also a major concern from asbestos exposure, as inhalation exposure can cause lung cancer and mesothelioma (a rare cancer of the thin membranes lining the abdominal cavity and surrounding internal organs), and possibly gastrointestinal cancers in humans. EPA has classified asbestos as a Group A, known human carcinogen.
- The main uses of asbestos are in building materials, paper products, asbestos-cement products, friction products, textiles, packings and gaskets, and asbestos-reinforced plastics.
- Asbestos use in the United States is currently decreasing
SOURCES AND POTENTIAL EXPOSURE
Airborne exposure to asbestos may occur through the erosion of natural deposits in asbestos-bearing rocks, from a variety of asbestos-related industries, or from clutches and brakes on cars and trucks. The concentrations in outdoor air are highly variable.
Asbestos has been detected in indoor air, where it is released from a variety of building materials such as insulation and ceiling and floor tiles. It is only released, however, when these building materials are damaged or disintegrate. Typical concentrations in indoor air range from 1 to 200 nanograms per cubic meter (ng/m3) (0.000001 to 0.002 milligrams per cubic meter (mg/m3)).
Asbestos may be released to water from a number of sources, including erosion of natural deposits, corrosion from asbestos-cement pipes, and disintegration of asbestos roofing materials with subsequent transport into sewers.For more information on asbestos, please visit the EPA website or give us a call.
Lead is a highly toxic metal that was used for many years in products found in and around our homes. Lead may cause a range of health effects, from behavioral problems and learning disabilities, to seizures and death. Children six years old and under are most at risk, because their bodies are growing quickly.
Research suggests that the primary sources of lead exposure for most children are:
- Deteriorating lead-based paint
- Lead contaminated dust
- Lead contaminated residential soil

Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints.
Molds produce tiny spores to reproduce. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet, and foods. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or un-addressed. There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.For more information on mold, please visit the EPA website or give us a call.
We provide internal demolition services which safely manage the demolition environment and the health hazards encountered during demolition work.
Asbestos is contained in many materials used in construction and therefore potentially encountered during demolition-for instance, thermal insulation, fireproofing, acoustical insulation, and decorative surfacing, and as a binder in roofing papers and floor tiling. During the renovation or demolition of industrial, commercial, and residential structures, these materials can be disturbed, generating aerosols of dust containing respirable asbestos fibers and placing those on site at risk of asbestos-related disease.
