Our job as your professional home inspector is to alert you, to the extent possible, to unknown problems and potential environmental hazards in your current or potential house. Just because some of these hazards may be invisible, this does not mean they call for less vigilance on your part. 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.
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 asbestos 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 sulphide, selenium, chromium, arsenic, mercury, and cadmium.

Mold (fungi) is present everywhere, indoors and outdoors. There are more than 100,000 species of mold, at least 1,000 of which are common in America. Species of Cladosporium, Penicillium, and Aspergillus are some of the most commonly found species. Mold most likely grows in bathrooms, basements, and anywhere else where there is dampness or water. Many types of mold routinely encountered aren’t hazardous to healthy individuals. Too much exposure to mold may cause a worsening of such conditions as asthma, hay fever, or other allergies. Fevers and breathing problems in a vulnerable individual are possible but unusual. When moldy material becomes damaged or disturbed, spores, which are reproductive bodies similar to seeds, can be released into the air. Exposure can occur if people inhale the spores, directly handle moldy material, or accidentally ingest the spores. Since all molds need water to grow, mold can grow almost anywhere where there is high humidity, dampness, or water damage. Most often molds are confined to areas near the water source. Removing the source of moisture through repairs or dehumidification is crucial in preventing mold growth. Correcting underlying water damage and cleaning the affected area is the best way to treat mold. If mold contamination is extensive, a professional abatement company may be needed.
