"I paid this company $600 to test the air in my detached garage. The results showed Cladosporium, which many professionals told me is extremely common. What happened next was one of the most uncomfortable experiences I’ve ever had with a home-service company. They sent me a remediation proposal for over $45,000, and in my personal opinion the scope, tone, and sheer intensity of the warnings felt completely disproportionate to the situation. The estimate was filled with pages of dramatic health claims that, to me, came across as fear tactics rather than professional guidance. When I asked questions, the owner was extremely rude and dismissive on the phone. The whole thing felt pushy and uncomfortable. After leaving an honest review, things escalated in a way that shocked me. The owner contacted me and offered a refund only if I signed a notarized disclaimer that he drafted. I personally found that very unusual, and I chose not to sign anything. What concerned me even more was what happened next: after I declined to sign the document, a negative review suddenly appeared online about my wife’s business — at our home address — claiming she had done work for him and stolen $600 from him. In my experience, this was completely untrue. My wife has never worked for him in any capacity. In my personal opinion, it felt retaliatory and deeply unprofessional. I ended up getting several second opinions from other mold professionals, all of whom felt the quote I received was excessive for what was found. Based on my experience with the customer service, the tone of the estimate, and the way things unfolded afterward, I would strongly recommend that other homeowners get multiple quotes before agreeing to anything. In my personal view, the way this situation was handled was alarming, unprofessional, and not in the best interest of the customer."

"Tim was wonderful. I put in this project on a Saturday night after finding mold behind a piece of furniture in my finished basement. The next morning Tim already reached out looking to set up an appointment Monday morning. Over the phone he explained the possible process of this project and put me in the books first thing Monday morning. He arrived right on time, looked at the area, and again explained everything. After about 15 minutes of doing his inspection, Tim gave me two estimates, which were both fairly priced. I selected the estimate that worked best for me, and Tim got working right away. Throughout the project, he continued to update me with what he was doing and what he had left. From when Tim arrived to when he left, it took him roughly 3.5 hours for the whole project. He did an excellent job, and I would recommend him to anyone."

"AMS is our HERO. The city sewer backed up and filled one third of our basement just before kickoff on Super Bowl Sunday. By halftime George had arrived. He calmly assessed the situation, and set up a time to return the following morning. His workers were polite, professional, and meticulous, and did an unbelievable job of cleaning up a horrible mess. By the end of the day the damaged items, sewage , and much of the smell was gone. Huge fans and a germ-killing ionizer ran for three days. When they were finished the floor was bone dry and absolutely clean. It occurred to us that the floor could not have been better cleaned if it were being prepped for painting. So we will be doing so. AMS has innate integrity and a wealth of knowledge across a wide spectrum. Any project can be entrusted to their competent hands. Chester and Jean Lehmann"

Customers say: Quick response

"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"

FAQs for mold & toxic material test projects in Norwalk, CT

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.
