"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."

"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!"

Mold Testing and Remediation FAQs, answered by experts

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.

While mold in the bathroom can appear black, it isn’t always the dangerous black mold strain Stachybotrys chartarum. This type of mold typically appears after a flood or a long-term leak. If you suspect black mold, you should get it tested by a local mold testing service to determine whether it’s safe to remove yourself.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

DIY kits are available for basic air quality testing, but professional services provide more comprehensive results and recommendations. While a DIY kit may seem cost-effective, a professional assessment is more thorough. Inspectors are better equipped to catch all pollutants and hazards, and you'll still need a professional to verify and act on DIY test results. Furthermore, some kits don't test for certain pollutants or only detect their presence without measuring specific levels (like mold spores). It's generally better to opt for a detailed professional assessment.

Toxic black mold on wood appears as dark green or black patches. It often has a slimy or wet texture and may spread across the surface in a spotty pattern. The affected wood might appear discolored, soft, and damp. Identifying black mold early is crucial because it can cause severe health problems when its spores are released into the air. Prompt remediation is necessary to prevent further damage and health risks.
