"The guy was really helpful but I couldn't afford what he charged me at that time. Otherwise I thought that they are a pretty good company. The guy who came out was really informative and helpful. As a matter of fact we had sewer damage and he had suggested about to claim with the metropolitan sewer industry. He was really pretty knowledgeable and very professional. The estimate was for around $4500 to $5000. It would have been well worth it but I couldn't afford it at that time. I think he was excellent personally. He was here when he said he would be here."

Mold Testing and Remediation FAQs, answered by experts

You can do a basic home water test, but we recommend having a pro conduct a more in-depth test. This method is accurate, and you’ll have a pro who knows your house helping you determine a plan of attack for anything out of the ordinary.

Powdery mildew tends to grow mostly on leafy plants. The mold itself isn’t particularly harmful, except for those who are allergic to mold. However, you should treat it like you’d treat the discovery of any other mold, and get rid of it immediately. Powdery mildew can spread to your home, which can cause expensive damage. 

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

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.
