"This was a great experience. I am very happy to have found Moldgone LLC. Everything was smooth from start to finish. The inspection was fast and simple, I received the quote quickly and the price could not be beat. They set the appointment and all communication in between were timely and informative. Jason & Curtis were my techs. They were friendly, fast, thorough, and did a wonderful job cleaning the model and repairing the area. I hope I never have mold again, but if I do, I will call them! Wonderful service and experience!"

"This is the second time I am using Val and his company. Thanks to Val we were able to identify a semi-hidden mold issue in our home from a long-term, slow leak. He was very professional and thorough. I was thankful for the easy-to-read report/test results we received. I would highly recommend Val for your mold testing needs."

"Excellent. Bruce is extremely honest and professional. I called Bruce after an exterminator warned me that he saw mold in my basement. Bruce came the next day, arrived exactly on time and upon visual inspection, told me that I did not have a mold issue. He could have easily set up treatment and I would have paid as I was afraid for the health of my family but Bruce is about as honest as they come. Jason"

"Mr. Rudd of Rudd's Indoor Environment and the service he provides are EXCEPTIONAL!. Mold can be a scary subject but if it is something you need to look into Mr Rudd is the man to look to. We used him to do a mold inspection for a home purchase. Very satisfied. He knows what he is doing and was very thorough, professional and very informative. At the same time he is easy to talk to and easy to contact if there are any follow up questions or needs. He often answered the phone right away, but if not, he returned my calls or emails quickly. He also made himself readily available for phone calls from any other involved parties (in our case the real estate agents) who need further explanations."

"I would HIGHLY recommend Atlantic Environmental and Keith Whitehead for mold remediation. They were nothing but professional from the first time I called until after the work was done. I can't recommend Keith's services enough. He came out and did a visual inspection of my property, informed me of the types of mold I was dealing with, recommended several remediation options according to my specific needs and worked with me to make sure I was completely comfortable with the whole process. He was there every step of the way. If you need mold remediation, call AE. You'll be glad you did!"

"This is not a mold remediation company. When you hire this company, you are simply getting a mold test. Be specific when you explain your problem and what you are looking to get done. The mold technician was in and out in 20 minutes. He took an air sample and one swab, that s it. For the price of $299. Once you get the results of your mold test, they refer you to a company that is in the business of selling mold remediation products. Originally as much as $1600 for mold bombs, sprays and commercial graded air scrubber. I negotiated down to $1195. Then settled on only what I needed. Know what you want, do your homework before buying products you do not need."

Mold Testing and Remediation FAQs, answered by experts

According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

Identifying harmful strains of mold helps prevent respiratory and allergic reactions.

Not necessarily. If the mold is only on the surface or in small areas, you may be able to clean it effectively without removing all the caulk. However, if the mold has deeply penetrated the caulk or the caulk is damaged or deteriorating, you should remove the caulk completely and replace it to ensure thorough mold removal and prevent future growth.

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

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.
