Mold Testing and Remediation FAQs, answered by experts

You can do more with a home test kit than just check your water’s hardness. There are a few types of tests. The first one is simple and involves a strip that checks your water’s pH balance. The second and more thorough option is a master test kit, which shows your pH plus the presence of nitrite, ammonia, and other elements through color shades. Unsurprisingly, the most thorough test is one you send to a proper lab for analysis

Yes, brown spots on a ceiling are usually caused by water leaks and can lead to mold growth, especially if you don’t correct the underlying problem. Ongoing water leaks and moisture issues will almost always result in mold growth, especially if you live in a warm climate. Mold is a health hazard, so get the root problem fixed quickly, clean it, and encapsulate the area to avoid mold formation.

The easiest way to know if it’s a leak or evaporation that’s causing low water levels in your pool is by conducting the bucket test. However, you can also monitor the chemicals in your pool for signs of imbalances or conduct a visual inspection of the areas around your pool in search of excessive moisture or cracks.

Some of the most common signs of sensitivity or illness from mold include congestion, eye irritation, difficulty breathing, and headaches. These symptoms may not lead to long-term health issues. However, some types of mold, like toxic black mold, can make you quite ill. You may experience respiratory issues, skin rashes, or neurological issues after exposure because of the toxicity. Infants, people with compromised immune systems, and older adults can suffer the most severe reactions.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.
