"The workers did a great job. The work looks clean and neat, and often worked in less than ideal weather conditions. When one worker was not available, when the weather was good, they scheduled another to take his place. Over all, they did a fine job."

Mold Testing and Remediation questions, answered by experts

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

Mold can be hazardous to your health. Some people are allergic to mold and experience a reaction when exposed to mold spores. The reaction varies from person-to-person, but can include a runny nose, skin irritation, and asthma attack. Mold can also be irritating to people who aren't allergic, causing respiratory, skin, and eye irritation. In some cases, mold exposure can lead to infections.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.
