Throughout the Denver metro and surrounding areas, there are many homes and commercial buildings that were built prior to 1980 and could potentially contain hazardous building materials such as asbestos and lead-containing paints. Materials with asbestos and lead paints but are in good repair are not dangerous to the occupants; however, when disaster strikes, these building materials may become disturbed and may then become potentially very dangerous. These dangerous materials may also be EPA and CPDHE-regulated materials which will require proper handling, cleanup, and disposal. In addition, water leaks can be a problem, especially if they go unnoticed for a period of time. High moisture levels can cultivate mold growth, which can also pose significant health risks to occupants and requires proper removal and cleaning to make the affected areas safe again.
