Frequently asked questions

Mold can be hazardous to people’s health and for this reason, often must be removed from buildings if it’s present. Mold removal specialists help Massachusetts residents and businesses rid their buildings and other structures of any mold that is present.

Most mold removal specialists offer a range of testing, removal and remediation services. They regularly work with property owners to determine which services are most appropriate for a particular building or structure that has mold.

Molds are various fungi that spread by releasing spores. Spores are most commonly found in warm and damp places, but they can exist almost anywhere.

No one knows for sure how many different molds exist in the world, but estimates range from the tens of thousands to the hundreds of thousands. Some molds that are commonly found indoors in Massachusetts are:


Some molds, such as the Penicillium found in blue cheese and used to make penicillin, are beneficial to people. Other molds, however, produce mycotoxins that negatively affect people.

Depending on people’s own sensitivities and the specific species present, mold might cause:

Minor nasal congestion, wheezing, and itchy or red eyes
Asthma attacks and allergic reactions
Shortness of breath and fever

Stachybotrys chartarum (also Stachybotrys arta) is a notorious mold known for its malignant effects and greenish-black color. It’s most often found in places where there has been excessive humidity, long-term condensation, flooding or other water damage, and can grow on gypsum board, fiber board, paper and lint.

Black mold may cause respiratory issues, rashes, chronic fatigue and headaches. Long-term exposure can lead to nausea, vomiting, and other serious reactions. A connection with idiopathic pulmonary hemosiderosis (repeated bleeding in the lungs) in infants hasn’t been established to date but is still being investigated.

Despite its name, black mold (and other molds) shouldn’t be identified based on look alone. To make sure a critical error isn’t made, mold ought to be identified by a specialist who is able to have it tested. Attempting to identify black mold by look alone may lead to adverse health effects or other issues.

In many cases, it’s not necessary to identify what particular strain of mold has infiltrated a home. Because most molds can negatively impact health, any mold that’s visual

Mold itself can be killed with a combination of 1 cup of bleach and 1 gallon of water. Bleach, of course, must be handled with care and never mixed with ammonia-based cleaners.

Simply wiping mold with a bleach solution, is often insufficient and sometimes unsafe. People are often exposed to the mold spores during the process, the spores can be spread when disturbed and the source of mold is frequently never fully addressed.

For these reasons, mold remediation specialists should be consulted when there’s an evident mold infestation. Mold remediation specialists will normally:

Perform a preliminary assessment
Set up a system to prevent cross-contamination caused by spreading spores
Control the area that has already been contaminated
Remove the source of the mold and the mold itself
Address any temperature or moisture issues that caused the mold growth
Complete a post-remediation assessment

Anyone who owns property in Massachusetts where mold is evident may want to talk with a mold remediation specialist about removing the mold.
