"We could not be happier with Charles Schwartz and Environmental Assessment & Solutions. We had a sudden severe mold outbreak from a leak in the boiler that caused serious damage to our basement. Charles was on scene within several hours, and was able to locate and stop the leak himself. He was highly organized, professional, and efficient and got the air testing and repair process underway in lightning time. As someone on chemotherapy to whom mold is potentially dangerous, I especially appreciated his professional background in health services. He always did what he said he was going to do, when he said it was going to be done. He saw us through every step of the process. Not only did he perform all services to our great satisfaction, he also seemed to genuinely care about our well being. This was a major crisis for our household, and we feel very grateful that we found such a consummate and experienced professional to help us navigate the process from beginning to end. Would highly recommend Charles and Environmental Assessment & Solutions to everyone."

"I called Adam’s Asbestos and Mold testing after we had a small fire and our contractor told us there may be an asbestos issue. Adam himself called me back within minutes, and he was at the house right away! He was professional and very detailed in his work. Best part was, that due to Adam’s report, our renovation was covered by insurance!!! Huge thank you to Adam’s Asbestos & Mold testing!"

"It went great! My parents had a couple of leaks in their house in an upstairs bathroom and mold developed in the basement. Apparently in NY, if there is mold in your house, you must get a NY State licensed mold assessor to determine everywhere that mold is or could be. We got John Skelly’s name from a mold remediation company. John talked to me and explained what things we could and could not do, and what we did and didn’t have to do. He gave us multiple financial options. His fees were very reasonable. It turned out he also is licensed to assess for asbestos and since my parents’ house was built in 1968, we asked him to also check for asbestos. When he got to the house, he looked everything over well and also took air samples which were sent to a lab. He took special pictures showing where there was moisture. Throughout the entire process, he talked to me on the phone as well as by text and email, constantly keeping me apprised of all that was happening. After he was done, he sent me an email with a letter explaining everything to me-and to the mold remediator we hired-that included what they needed to do and where. It was a detailed letter with an incredible amount of data referring to moisture content, types of mold, and possible reactions to living with mold, among other things. He had a lot of technical equipment. He took multiple pictures showing where the mold and water damage was and included these in his report. Many of these photos were taken with special cameras and equipment. He even cited an incredible array of research and information if we or the remediators or anyone else wanted more information or knowledge. I forwarded the email to the remediators and they got to work. At the remediator's suggestion we had John come back again to “clear” the work they did, when they were almost done. He looked everything over well and took more air samples which he again sent to a lab. He told the remediators to do a few minor additional things but said they were primarily done. He did great work and was very thorough. For example at one point the mold remediators told him they had detected moisture content in one place a week before John came to the house even though he did not detect any there a week later. Rather than leaving that out of his report, he went back to the house and took a moisture reading again, and then included that information-citing the photos they took showing the moisture readings the remediators got-when they had been there. John is obviously smart and clearly knows what he is doing. When he wrote what the remediators needed to do, he wrote out quite an elaborate plan for them including the precautions they should take and what equipment they should use and where. While I’m pretty certain that many remediators know most of what he discussed, I’m fairly certain it was still very useful for them to know his recommendations since he is licensed to evaluate if and where mold is and how to best deal with it. It was also useful to me to know the extent of the work that was needed as well as the precautions the remediators needed to take to keep my elderly parents safe during the process. It was also impressive that he had all of that knowledge. In addition to everything else mentioned, John was also very supportive and was extremely helpful. When he learned from the remediators that my parents had a leak that hadn’t been able to be seen before the sheetrock on the walls and ceilings were down, he got out a ladder and looked at the leak carefully, even though it was way up in the ceiling in their basement. He had my Mom flush the toilet and took video of where the water was leaking so that we could show it to the plumber we next hired, as well as to the insurance company to demonstrate where the leak was and that it couldn’t be seen until the drywall was down from the walls and ceilings. He told us with this new information that he believed there was a leak in some part of the toilet and that this is clearly causing a leak and is likely what caused most or all of the mold. He really went above and beyond for us. He didn’t need to have done any of what I just mentioned above. In the end he wrote up another report talking about the remediators and the leaks. He also wrote it so that we could show the insurance company and let them know what was going on. Between John and the mold remediators my parents and I ended up having what could have been a very dragged-out, annoying, costly situation, be something that was as painless as possible and was even quite interesting and informative. As I said above, John really went above and beyond for us. He didn’t need to do some of the things he did. You cannot go wrong if you hire him to assess mold or asbestos or anything else he is licensed to evaluate, in your home. I very highly recommend John Skelly."

"It was frustrating. I bought the service because of an Angie's List promotion. When I received the package I opened it and saw what it was and set it aside. I was very busy and planned to get to it in a few days. I had to go out of town for a few days, then I had a ridiculous string of bad luck with multiple car breakdowns. I have a neuromuscular disease so everything I do is very difficult and exhausting. With so much happening, I forgot about the test kit. Then after a couple weeks I get a call from Mold Lab asking about the kit saying it was past the due back date and they were going to charge me $25 a day late fee on the pump. I was stunned! I opened the box and there was nothing inside saying it was due by a certain time. I re-read the Angie's List ad and there was nothing there either. The lady was very rude and kept interrupting me saying the same things over and over like maybe I would finally understand if she kept repeating it. I understood the first time. She wouldn't listen to understand I didn't know about the deadline but now that I was made aware of it I would do the testing that day and ship it that day. What else could I do? That wasn't good enough she had to repeat her lecture a few more times. After sending it in I was told I would receive a text when it was complete and I would receive an email with results within a few days. After a month I called and the same lady answered. She claimed to have sent an email, but didn't know the date and told me to check my junk mail folder. I checked everywhere but had no record of it. I explained I hadn't received the text either, she had no response for that. So she sent an email while we were on the phone and I received it immediately. I printed out the results but without the proper training or experience in laboratory sciences it was basically useless."

"I've been in my home over 12 years so things tend to need work. RMR is the first contractor who provided a detailed explanation of what work was to be completed, time estimate, cost and how payment was to be made. It was a contract to be signed my myself and the owner, Wayne. A copy of the insurance certificate was also provided without my having to ask for it. The work was performed in a timely manner. All work was based around my schedule not the contractors schedule. The basement was cleared of all affected areas. The area was completely cleaned of any and all debris related to this job. I can walk in the basement now without the smell of something rotten, mold. I was very impressed with the work ethic of Presley and one other man whose name I cannot remember. RMR was very personable and easy to work with. I would give this company an A+. You won't go wrong hiring this company to handle any mold issues you might have."

FAQs for mold & toxic material test projects in Chester, NY

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
