"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."

"The team from Stay Dry was very professional. They were informative and transparent when describing what the work would entail and sent me pictures and updates throughout the day. They went out of their way to provide a thorough service. It is hard to know who to trust when having mold remediated because the levels of training and expertise are very different across companies. They are skilled and they care about the quality of their work and customer service. I will hire them again for the next project."

"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

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.

The primary signs of mold in an ice machine is a musty odor, slime buildup, and discolored ice. If you notice any of these signs, clean your ice maker immediately.

Not necessarily. If the mold is only on the surface or in small areas, you may be able to clean it effectively without removing all the caulk. However, if the mold has deeply penetrated the caulk or the caulk is damaged or deteriorating, you should remove the caulk completely and replace it to ensure thorough mold removal and prevent future growth.

The spread of wood rot results in a physical breakdown of the wood’s cellulose and lignin, causing it to become spongy or brittle. This can lead to structural damage. Water won’t damage the physical structure of the wood, while mold can eat away at the material and cause structural damage over a much longer timeframe. When further considering water damage versus mold versus wood rot, all three issues can create a musty or damp odor in the area. All three can also cause discoloration of the wood.

The most common reason for a smelly dishwasher is a dirty dishwasher filter. The filter is responsible for catching food while your machine is running to prevent clogs. Over time, that filter gets more and more filled with food particles. Cleaning your dishwasher filter monthly can keep the smell at bay.
