Mold Testing and Remediation FAQs, answered by experts

There are two types of mold symptoms in the home: visible mold and unexplained health issues. If you have allergies out-of-season, brain fog with no other obvious cause, constant congestion, and other such symptoms, you may have a mold problem. Oftentimes you can smell mold in your home, even if you can’t see it. 

Both wood-burning stoves and fireplaces can emit smoke and other combustion gases that are harmful to human health. According to the American Lung Association, wood smoke can lead to coughing and wheezing as well as long-term health impacts like increased risks for heart attacks and stroke. 

Newer models meet the modern efficiency standards set in 2020 by the Environmental Protection Agency for cleaner burning, more efficient wood stoves. Regular maintenance can also minimize smoke.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

Although you can run a DIY test for mold inside your home by buying a test kit, you won’t know whether the strain of mold is dangerous. The best way to test for mold in a home is to hire a professional who can determine the specific type of mold that you have. If you’re worried you exposed yourself to mold and it’s making you ill, you could request a health test. Your personal doctor could test your urine, take a nasal swab, or test some body tissue to determine your potential exposure to mold.

Mold can grow anywhere in a home where moisture accumulates and doesn't dry out, particularly in areas with poor ventilation. Common materials affected include insulation and drywall. The most frequent locations for mold growth are attics, basements, crawl spaces, wall cavities, bathroom and kitchen walls, exposed foundations, windows and window sills, air conditioning and heating vents, and around fireplaces and chimneys.
