"Robert explained a person who checks for mold cannot, ethically, remediate the mold. It would be a conflict of interest. I appreciated that information. He was thorough and explained what he was doing. Luckily, I did NOT have an air quality problem. I highly recommend his services."

"Julius and Aaron, did 8 rooms two sets of stairs and closets in about two hours. Now normally I would think it would take longer but they did a phenomenal job! They were professional and thorough. The one thing that I will say is the standard cleaning with this company is that just, standard. The one room with some stains from previous owners looked to be gone but as it dried the stains were visible again. Otherwise I am completely happy with the rest."

"I know that I'm being picky but there were a few paint splatters left behind. But it was ceiling work so splatters are probably expected. Other than that the work was good and I am confident no mold will return. The work was also quickly scheduled and finished quickly."

Mold Testing and Remediation FAQs, answered by experts

It is safe to remove old linoleum, but it may require the help of a specialist due to the risk of asbestos in the material. Before you cut into linoleum or try to peel it up, have it tested for asbestos. If it tests positive, professionals will need to remove it to prevent the risk of health issues from airborne toxic particles. If it’s asbestos-free, DIY removal is possible and safe.

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.

According to the EPA, mold allergies are common and can cause skin irritation, respiratory problems, headaches, and other allergic reactions. Mold allergies can also trigger asthma attacks in people with asthma. Additionally, some molds produce mycotoxins, which can lead to very serious conditions, like lung cancer.

If you see mold spores on walls, flooring, or ceilings, it’s best to call in a mold inspection pro to investigate. Similarly, if you smell signs of mold—musty, earthy, rotting wood, or stale scents—it’s time to call a mold inspection professional. 

Other less-obvious times when you should have your home inspected for mold include:

  • After flooding

  • After home water damage

  • Having ceiling or wall damage

  • Buying or selling a home

  • After a persistent unexplained cough or allergy symptoms 

  • Noticing discolored surfaces

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.
