|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. 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.
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

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.

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.

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.

Termites, which play a positive role in recycling wood and plant material, become a problem when they consume structural
lumber. Every year thousands of U.S. housing units require termite treatment. These pests cause serious damage to wooden structures
and posts and can also attack stored food, household furniture, and books. Successful termite management requires special
skills, including a working knowledge of building construction and an understanding of termite biology and identification.
In most cases, it is advisable to hire a professional pest control company for the inspection and control problem.
Carpenter Ants. Several species can damage wood in building and other structures. Though ants don’t
eat wood, they bore into it to make their nests, sometimes causing serious structural damage. Also, they nest in hollow doors,
cracks and crevices, furniture, wall voids, and termite galleries. New building infestation occurs when land-cleaning in the
area disturbs existing native colonies.
Wood-boring beetle larvae feed on wood and wood
products. Adults of some species bore holes into plaster, plastic, and soft metals. Many species cause problems when emerging
from wood in newly constructed buildings because they leave small circular or oval exit holes in the wood. To avoid these
problems, infested wood must be kiln-fried before being used for lumber. The species Deathwatch Beetles is primarily found
in soft woods (girder, beams, foundation timbers, some types of furniture, with some species attacking books). False Powderpost
female beetles bore a tunnel, or egg gallery, into wood or other materials, and then deposit eggs in pores or cracks within
the tunnel. Adults of some species bore through such soft metal as lead and silver, as well as plaster and other non-wood
materials. Affected structural wood should be removed and replaced whenever possible.
damage in buildings is likely to be more cosmetic than structurally weakening. They drill small ½ size hole on the
exterior wooden surfaces (soffit, facia, and deck areas) and lay there eggs. The males carpenter is harmless because is does
not has a stinger. These insects are mostly active in the spring and summer.
