"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."

"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!"

"I had no first-hand experience with mold until it showed up in my kitchen. However, I knew enough to talk with more than one expert. Mr. Watts was the 2nd mold professional I interviewed. He demonstrated a far better skill set/experience in mold and mold remediation than others I spoke with. He was quick to come in, access the issue and provide a remediation estimate that was very fair. Along with information I googled, he helped me understand the dynamics of mold and how to rid my home of it. His team was professional, courteous, quick and, respected my home. After the work was completed, Mr. Watts personally delivered my Certificate of Mold Damage Remediation. I recommend Watts Commercial Cleaning! He is so very helpful with his expertise."

"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!"

"Every person who came to our home was wonderful. And the team did a super job and left everything clean. And their contract entitles us to free inspections for five years and they would remediate any mold found at no cost—that shows they really stand by their work."

Mold Testing and Remediation FAQs, answered by experts

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells. 

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.

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.

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.
