"I saw NAL East Environmental, read their Profile & was extremely impressed. Their Inspectors’ are Highly Educated Professionals. Words can’t describe how Grateful I am for Mark Stern & Joe Chairmonte. Testing was explained with Professionalism, Knowledge & Compassion. Mark is a Genuine Professional. He was Respectful & Kind as he explained and knew what should be tested. Joe was already set up. They were extremely thorough. After testing, Mark said, “Please call with any questions,” He was true to his word. After finding Acute Mold issues in Our Rental Home of 17+!years. Mark showed much care for Our well-being. It’s RARE to find a Co. with such Caring Inspectors w/High Moral Values, Yet, here they are!! I hired Mark & Joe again for Surface Testing. I’ve since referred Mark & Joe to Family. NAL East is The BEST! Thank you & Many Blessings to Mark & Joe. You are Amazing Assets to NAL Eastern & Our Community!! Jacqueline W., Yardley, PA"

"Straight forward and efficient, great communication, costs transparent. When presented with challenges of temporary electricity outage was resourceful and creative to get the job done even more than predicted. Cleaned up after work done. Respectful and honest. Would highly recommend! I should have had them do this work years ago, glad I worked with Luis & Steve!"

"Absolutely outstanding service and work. Chris, the owner, answered my call within minutes and came to my house the next day to give me an estimate on needed mold remediation. He answered all of my questions, and when I asked, he referred me to an excellent certified tester who also came the next day. Speed was important to me because I have a mold allergy. Chris came up with a comprehensive plan to do the job right and still keep it allergy-safe. He and Rene taped down paper though the house so that the mold-covered tiles and drywall he removed did not get on my floor. They taped a heavy plastic tarp with zipper opening on the door to the room they worked and and wore protective boot covers that they changed each time they left the room they were working in. They left my house as clean as when they came. Rene and Chris were professional from beginning to end and showed attention to detail to avoid cross contamination and remove the mold effectively at a fair price. They addressed my issues effectively and were so pleasant to work with. It made it seem like they were family watching out for me. And now I am breathing better than I have for a long, long time. Thanks Chris and Rene for a job well done."

Customers say: Super punctual

"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."

"Green Solutions is absolutely the company to use when you find yourself with mold problem. John and his people were great. What started out as a small, two day job turned into a week of work. John kept us informed every step of the way as the problem became much worse than what we originally thought. The options he offered were thoughtful and very helpful."

FAQs for mold & toxic material test projects in Trenton, NJ

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.
