"When I called the mold company for my lab results. They gave me a person named Ricardo Echeverria, Senior Mold Analyst to call for the results. He verbally told me that the cause was something like a remodel, construction going on. There was a red flag for a VOC called Methylene Chloride--Banned outdated paint. I sent Ricardo and email asking if I can have a report of what he said in writing. I only received a contaminants list. I said, I am not a scientist and do not understand the lab results.I never received a response back from him. I called Jeremiah Bancroft a few times and asked for a written explanation of the causes. He could not supply me with a written explanation because it was a legal issue. I asked for his help. I need your help. Jeremiah said, go to your primary care for a doctors note. That was the last time I spoke to him on September 19, 2024"

By choosing C2G Environmental, you can be assured that your environmental project will be handled with the utmost care and professionalism. C2G Environmental is a full service environmental company. What sets us apart from other companies is our highly trained staff of professional geologists and hydrologists, as well as technicians. We do not use sub-contractors or rental equipment. We are authorized by New York, Connecticut, and New Jersey to remove and haul contaminated material. Our Services: Tank Removals, Abandonments & Installations, 24 Hour Emergency Spill Response, Ground Penetrating Radar (GPR), Geoprobe & Vac Truck Services, Water, Soil, Air Testing/Monitoring , Liquid/Soil Transportation & Disposal, Petroleum Facility Compliance Audits (Class A/B Operator), Phase I & II Environmental Site Assessment, and more.

"This review was 5 stars until about a week ago. I needed a new oil tank installed last year. C2G came out and performed the task. They were the most cost effective option so I went with them. The install was a success and the tank looks great. However, a couple weeks after I had to have them back out again to fix the leaking oil filter. They came out, tightened it, and it stopped leaking... for that period of time. Fast forward to this year and getting ready for the colder months. I noticed a small puddle underneath the filter, again. This would be the 3rd time I would have needed them to come out to repair it. At that point I question if it was installed correctly or not. I called them asking if they could come out, they said with a fee and showed opposition in understanding where I was coming from, saying I was outside of their 45 day guarentee. The lady I spoke with said she would speak to her supervisor and follow up with me. That never happened. I had to have a plumber over to my house, and luckily he was able to repair the leak. The rubber gasket was malformed inside, causing the slow leak. Despite a smooth install, I was really disappointed with how they treated a previous customer. They really didn't care that their work was sub-par. A newly installed oil tank should not be leaking a year later. I will not use this company again."

Mold testing and remediation services FAQs

Some states require mold removal specialists to be licensed, while others require licensed mold testing companies to create remediation protocols that any contractor can carry out. You can use our state licensing tool to find requirements in your area. In either case, it’s imperative that you hire an experienced professional for mold removal to ensure the safety of your home and your family.

It’s possible to scrub mold off of visible surfaces yourself, but it’s not usually a good idea. Mold is not only a potential health risk, but it’s also difficult to treat in its entirety, especially because it can grow behind walls and in other hidden areas a DIYer might miss. Since mold is a serious and often pervasive issue, you should hire a professional that will remove all of the mold—including any that might be hidden—run industrial air scrubbers to remove airborne particles, and complete mold testing to ensure the underlying problem is solved.

The most effective way to remove mold includes testing affected surfaces and the air for spores, creating a protocol for removal, carrying out the steps within the protocol, running air scrubbers for the recommended amount of time, and then completing a post-remediation round of testing to confirm the issue is solved. Since this work is very involved and there are health risks if done incorrectly, you should always hire an experienced professional to handle mold removal.

The average cost for mold remediation is around $2,200, and most projects fall somewhere between $1,100 and $3,300. Your total will depend on many factors, including the surface area that is affected by mold, the extent of the issue, how much building material your professional needs to replace, whether or not testing is necessary for safety reasons, and existing indoor air quality.

Mold removal will take between one and five days in most cases, but severe mold issues can take several weeks to correct. Your timeline will depend on how much mold there is in your home, where the mold is located, and how much testing and aftercare is required. If you have mold behind your walls or you have an excessive amount of mold that requires removal and running air scrubbers for several days, you could be looking at over a week for the process to be completed.
