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.
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.

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.
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, 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.
Wood Wasps and Horntails. Wood wasp damage in buildings is likely to be more cosmetic than structurally weakening. Emerging wood wasps can chew through any substance: wallboard or plaster walls, hardwood floors, carpeting, linoleum, non-ceramic floor tiles, and other interior surfaces.
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.
