The cost of this inspection in The Washington D.C. and Maryland area will vary depending on the size and complexity of the home, but will usually lands somewhere in the $200-400 range for a typical residential building.

A typical mold inspection involves the inspector talking to the property owner about any areas where they have seen mold, or where there have been moisture problems or water damage in the past. The inspector will go over the house thoroughly, looking in places known to be prone to mold growth. If there is a chance mold is growing in an inaccessible space, the inspector may have to damage a section of drywall or remove paneling to get a better look. If mold is detected, the inspector will try to find the source of the moisture that is causing the mold and talk to the homeowner to develop a remediation plan.

  • What is mold?

    Molds are a type of Fungi that produce long tube‐like structures called hyphae (pronounced Hi Fee). As the hyphae grow, they develop into hairy or fuzzy looking masses called “colonies.” Depending on the type of mold and growth conditions, colonies can have a wide variety of shapes, sizes, textures, and colors (black, dark olive, pink, white, green, bluish green, yellow, brown, light gray, dark gray, red, orange, or various shades of these colors). There are many black molds, many of which are not the “toxic” variety. In addition to the hyphae, mold colonies can also contain tens of thousands of tiny structures called “spores.”

  • So what types of mold should I worry about?

    Alternaria, Aspergillus, Chaetoneum, Penicillium, and Stachybotrys are all species of mold that produce mycotoxins and raise cause for concern if found within an indoor environment.  These species of mold can be found outdoors, but it is not in a confined area where the mold spores have the opportunity to build up to the level that can cause problems. The side effects of being exposed to mycotoxins produced by these species varies from person to person. Some may experience severe reactions while another individual in that environment is perfectly fine; very similar to allergies.

  • Do we use a infrared testing for mold?

    Yes. A mold inspection is, for the most part, a visual inspection of a house. Using a good flashlight and with the use of our infrared camera, we can help identify moisture issues before they become a major problem.

  • How long does it take for mold to spread in walls?

    Mold is persistent and fast. In only 24 to 48 hours, mold can germinate and grow. The spores then begin to colonize in three to 12 days and then become visible within 18 to 21 days.
