"Mold test took air samples inside and out after we discovered some questionable spots that worried us. Samples are sent to a lab for analysis. We subsequently purchased a mold remediation kit from another firm and treated the house. We are breathing easier now. Thanks!"

"This was a really good company and I think they did great work HOWEVER if you are suffering from a respiratory condition called CIRS you will need to hire a specialist. I did not know this at the time. There are very, very few mold remediation companies that are qualified for this specific mold removal process."

Mold Testing and Remediation questions, answered by experts

Yes, mold behind drywall can affect your health, even if it is not visible. Mold releases spores and mycotoxins into the air that can be inhaled, leading to various health issues including respiratory problems, allergies, asthma symptoms, coughs, and other infections. While individuals with pre-existing conditions like allergies, asthma, or weakened immune systems are particularly vulnerable, anyone can be affected by prolonged exposure. Additionally, if left untreated, mold can spread throughout your home and compromise its structural integrity, resulting in costly repairs.

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.

While home mold tests can provide a simple identification of mold presence, they lack accuracy and reliability. These kits may detect mold spores but can't pinpoint the source or identify the type. Professional testing, combined with an inspection, is more comprehensive and leads to actionable next steps. 

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.
