"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 cannot say enough about my Awesome experience with Zero Mold. From the FREE & and ACCURATE estimate! To the VERY kind, on time and friendly service. This company deserves 10/5 stars in all honesty. We had been experiencing a number of health issues that prompted us to look into getting an Air Quality test. We put in a request on Home Advisor and Taylor with ZeroMold was the first to call within minutes. A couple simple questions he asked about what we were experiencing and within 10min from the time I placed the request on Home Advisor we were booked and scheduled for an estimate appointment. The estimate day comes, we get a courtesy call letting us know his ETA, he arrives, very professional and very knowledgeable about mold and toxic material in general but he was also very serious about how severe the issue we were having was. My wife and I were truly unaware of just how bad and toxic the air we and our dog were breathing. Taylor gave what I would call scientific facts about the effects of mold along with the why and how this was urgent for us to fix regardless of if we chose Zero Mold or not he Genuinely cared about our welfare. Now to the good part. The day comes for the fumigation to take place. Again we got a courtesy call about 30min ahead letting us know his ETA. We arrived to let him in so that he could begin remediation. The process took about 2.5-3hrs from the time I left him at the house to the time I got his call stating that he was finished. A few hrs later upon returning to the house I was able to tell an immediate difference in my breathing when I stepped inside, the air not only had a clean smell to it but to my Lungs it felt better! I felt like I was finally breathing fresh air. I went to the main troubled areas we had most of the mold and where it was most difficult to breatheâ ¦I was able to breathe without any restriction/heaviness/stuffiness or any of the other breathing issues we were having prior. THIS IS A DIFFERENT HOUSE THAN IT WAS Just 24hrs AGO! Do not let the Free Estimate and Low Price fool you into thinking youâ  re not getting quality service! This is Legit good work here. It should also be noted that not 1 single wall had to be cut open, not 1 additional contractor had to be called and no additional construction costs were needed, just the ZeroMold service itself. ZeroMold knows what they are doing and the technician Taylor who did our service went ABOVE AND BEYOND! I have had professional cleaning services come and clean my home/office/job sites who are double the price but donâ  t do half as thorough of a job as this company did. Simply put I got more than I paid for and I can guarantee that anyone I know or meet that mentions Mold problems to me in the future will be getting ZeroMold contact info. Phenomenal Job! I cannot thank Taylor and ZeroMold enough!"

"We recently worked with Flood Solutions after our basement flooded, and Megan—our inspector and project manager—was incredible. She was thorough, patient, and took the time to explain every step of the process, which meant a lot as an allergy sufferer worried about proper remediation. She honestly deserves her own show on mold education! When the team arrived, they were organized, detailed, and clearly cared about doing things the right way. Matthew and the crew also did a fantastic job finishing everything and making sure we felt informed and comfortable throughout. We can’t recommend Flood Solutions enough. If you need a trustworthy team during a stressful time, call them—and hopefully you get Megan, she’s a gem!"

"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!"

"Hands down the best!!! While selling my property we discovered mold. I spoke to several remediation companies but Green Home Solutions stood out (way out!) with the most comprehensive processes! Brian was extremely helpful in explaining what I was facing, the step-by-step process it takes to remediate and future prevention options. I came up with 1001 questions daily; Brian answered each quickly, with the best attitude and genuine care. He moved things around on his busy schedule to fit my timeline. The level of service and professionalism I received were premier; and there are not enough words to express the confidence I have in this company and the phenomenal work they did. My post-remediation scores were much better than I expected. Once the results were out, Brian took the time to speak to my home buyers and made them feel equally comfortable. He offered them a warranty on his work and products which not all companies did. I would recommend Green Home Solutions and Brian to anyone who is facing a mold problem. They hold your hand, make the painful process easy, complete it fast and at a reasonable cost. I hope I never face mold again, but if I do, Green Homes Solution is my go-to. Thank you Brian!"

Mold Testing and Remediation questions, answered by experts

Certainly, DIY mold tests are not perfect when trying to determine whether you have a mold problem. They could give you a false positive reading, or they may fail to detect mold that’s behind a wall, especially if the infestation is still small. Ultimately, you should seek a mold inspection if the DIY test gives you a positive result, just to be certain. And if the test is inconclusive, it’s probably worth seeking an inspection from a pro.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.
