Our job as your professional home inspector is to alert you, to the extent possible, of unknown problems and potential environmental hazards in your current or potential house. Ours is a non-invasive visual inspection of your property. While we may be able to alert you to possible problems, our basic inspections are no substitutes for specialized contaminant testing.
Radon is a radioactive gaseous element produced in the disintegration of radium, a radioactive metallic element. It cannot be detected by the senses and can be confirmed only by sophisticated instruments and laboratory tests. The gas enters a house through pores and cracks in the concrete or through floorboards of poorly ventilated crawlspaces, especially when wet ground allows the gas to escape easily through the soil and disperse in the atmosphere. Radon is a lung carcinogen: the National Academy of Sciences estimates radon causes some 15,000 to 22,000 lung cancer deaths annually. The U.S. Surgeon General and the EPA recommend all houses be tested for radon. Houses with high radon levels can be fixed.
Asbestos is a mineral fiber that can be positively identified only with a special type of microscope. There are several types of asbestos fibers. In the past, asbestos was added to many products to strengthen them and provide fire resistance and heat insulation. If disturbed, asbestos material may release fibers which can be inhaled into the lungs. Asbestos material that crumbles easily if handled or which has been scraped, sawed, or sanded into a powder is more likely to create a health hazard. Breathing high levels of asbestos fibers can lead to an increased risk of lung cancer, mesothelioma (cancer of lining of chest and abdominal cavity), and asbestosis (lungs scarred with the tissue). Houses built between 1930 and 1950 may have asbestos insulation. Most of today’s products do not contain asbestos. If asbestos material is more than slightly damaged or you plan changes that might disturb it, you require a professional for repair and removal. Before home remodeling, find out if asbestos is present.
Lead is a highly toxic metal used for many years in products in and around homes. Lead’s adverse health effects range from behavioral problems and learning disabilities to seizures and death. Because their bodies are growing quickly, children age 6 and under are at greatest risk. Primary sources of lead exposure for children are deteriorating lead-based paint, lead-contaminated dust, and lead-contaminated residential soil. Lead might be present in any home built up until the 1940s. Rarely found in source water, lead can enter tap water through corrosion of plumbing materials. Homes built before 1986 are more likely to have lead pipes, joints, and solder. New homes are also at risk: even legally “lead-free” pipes can contain up to 8 percent lead and leave significant amounts of lead in the water for the first several months after installation. Since the 1980s, EPA and its federal partners have banned or limited lead used in consumer products, including residential paint. Federal regulations limiting the amount of lead in paint sold for residential use started in 1978. If your property was built before 1978 or you are considering remodeling, renovating, or repair, you may wish to think about lead inspection. Water quality can be compromised by such other trace elements as iron, excess acidity, manganese, calcium, magnesium, mineral salts, hydrogen sulfide, selenium, chromium, arsenic, mercury, and cadmium.
