A CL-100 Wood Infestation Report is necessary whenever a home or building is purchased, sold, refinanced, or undergoing major renovations. This report will provide the property buyer with an understanding of the presence and extent of any wood-destroying organisms (termites, carpenter ants, etc.) that may have infested the structure. It also outlines proposed treatments for these pests if they are found to be present in the home's structure. A CL-100 is generally required by lenders when issuing loans on properties. It should always be obtained before buying or selling a home so both parties know what they are getting into and can take steps to prevent further damage.
