Marc was great! If you need a mold test done, he is the man to call. He goes the extra mile and provides services that other mold companies do not.

10 out of 10 — highly recommended. We spoke over the phone, and he sounded very down-to-earth. His quote was also reasonable compared to other companies I contacted. We scheduled a day for him to come out and conduct an inspection for heavy metals in the soil in my backyard. He arrived right on time and explained his entire process in clear, easy-to-understand language. He took his time answering my questions and made sure I felt comfortable with each step. Overall, a very smooth and professional experience.

As a tenant, I felt completely ignored by my landlord when I started getting sick and suspected mold in my apartment. Marc from Knight Environmental Consulting was the first person who actually listened and took me seriously. He came out quickly, treated me with respect, and performed a full environmental inspection that uncovered exactly what was causing the problem. His report was detailed, professional, and backed by lab results — it gave me the evidence I needed to finally get action taken. Marc genuinely cares about people’s health, not just collecting a paycheck. He explained everything clearly and gave me advice on what to do next without scaring me or overcharging. If you’re a renter dealing with hidden mold or air-quality issues, don’t wait — call Knight Environmental Consulting. Marc is honest, compassionate, and truly knows his field.

Marc from Knight Environmental Consulting is hands down the best environmental professional I’ve ever worked with. From the moment he stepped on site, you could tell he knew exactly what he was doing. He came fully equipped, explained his process in plain language, and treated the situation with urgency and care. The level of detail in his testing and final report was outstanding — precise measurements, clear photographs, and easy-to-read explanations that helped us understand the scope of the problem and the right next steps. What really stood out, though, was Marc’s integrity. He didn’t try to oversell or exaggerate — he just focused on facts, science, and helping us protect our health and property. If you’re dealing with mold, asbestos, or any indoor air quality issue, this is the person you want. Professional, honest, and deeply knowledgeable — Marc sets the gold standard in environmental testing.
