"Showed up on time, did an excellent job removing the mold and coating the attic and crawlspace. I found some mold when pulling up some wood paneling. They removed some sheet rock and treated the studs at no additional charge while they were here."

"I was very happy with David’s work. There are other mold inspectors who offer cheaper options, but you pay for high quality inspection with David. This is the sort of stuff that you don’t want to cut corners with. From the get-go, I felt assured of David’s understanding and expertise in the area of mold. I was pleased with his gameplan that was tailored to my home. It was thoughtful and deliberate; nothing seemed cookie cutter. After the actual inspection, he provided a huge amount of detail and rigor to the lab reports and analysis to help us understand the reality of the situation. He spent ample time walking us through the report and explaining to us best next steps. Additionally, he also provides a detailed gameplan and evaluation criteria for prospective remediators to ensure that they do a good job not only remediating, but also cleaning the toxins. He also brought empathy to his work given his own personal history with mold. I can tell he really cares about his work. He was personable and warm and was very considerate of us. The area of mold inspection and mold remediation seems like a bit of a Wild West, and finding somebody reliable can be challenging. But based on my own experience, I would recommend David to do the inspection well. Thanks David."

"Mike did a great job explaining the process he uses and what to expect. He arrived on time and did a very thorough job, following up with emails to make sure I was satisfied. The treatment was successful and there is no more mold/mildew smell."

"An unknown animal entered from chimney flue into the fireplace smoke chamber. The animal made noise above damper at night. I called the first company to check the chimney during day time and they found nothing. The next day morning the mason came and checked the chimney from roof. He installed a sturdy cap after he confirmed that no animal was there. Actually he missed the animal because he could not see the complete smoke chamber from roof. <br /> So something happened that evening. The animal was sealed inside and tried extremely hard to get out. It made very terrible scratching noise with the damper. <br /> I called 3 animal exterminators who claimed to provide 24/7 emergency service. Darren was the only person who picked up the phone call, while the other two companies had no response even after I left voice message. <br /> Darren came after 30 minutes with all the available traps except raccoon trap. To our surprise, it was a big raccoon inside the chimney. He went up and took off the rain cap, so that the raccoon could escape later that night. <br /> He and his buddy came back the next day to confirm that the raccoon has left. Darren brought a camera to check the smoke chamber while his buddy looked down from roof at the same time. They put the cap back, and found the trace of raccoon. They set up two traps on its path for 4~5 days and check them every morning. In the end, we didn't trap the raccoon. <br /> The total cost includes $400 for emergency service and $400 for the following service with 1 year warranty of no animal in chimney. The cost is higher than what I expect. But they had quick response, prompt action, and provided professional service. I recommend you call them if you need 'emergency service', since you may also find they are the only company that demonstrates 24/7 service. <br />"

FAQs for mold & toxic material test projects in East Nassau, 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.
