"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."

"He came when he said he would. Agreed that if it was under sink. Recommended we cut out bottom piece of chip board that was severely warped from earlier exposure to water. We decided to wait until after holiday’s and he drilled two holes through the board to access between cabinet and floor. He sprayed a non toxic enzyme that combats the mold. Mold odor disappeared within a few days and was completely gone in a week. I will have him back to complete work."

"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."

"In early November, we asked Mike to gave us a free inspection <br /> and estimate for the mold condition in our attic. He explained in details to me <br /> how he thought the mold condition was, what he was going to do to treat the <br /> mold and what we can do in the long run to prevent the mold  coming back again. He even explained to me <br /> that the mold condition we had was minor to median, and we should not feel panic <br /> or intimidated if other company gives us estimation saying how serious the <br /> condition is and we must take action right away , etc. <br /> His quote was very reasonable and he sounds very knowledgeable <br /> and honest about our mold condition. So we decided to ask him to help us to do <br /> the mold remediation.  He came on time <br /> and finished the work in a couple of hours. He sprayed on the building material <br /> of the attic to remove the visible black mold and he fogged the attic to break <br /> down and consume the active mold spores. He also helped me to move the insulation <br /> of the attic to allow better air circulation of the attic . The same night, he <br /> sent me a detailed report and a certification showing my attic is mold free <br /> now.  One week later he came back for a <br /> follow ?up but no one was home at that time so he came back again the next week <br /> to ensure everything in my attic is good.   <br /> Mike has been very patient , reliable, professional and accommodating <br />  during the process from estimation to <br /> follow up. His quote is very reasonable and his work is guaranteed for five <br /> years and the warranty is transferable if the house is sold. I would recommend <br /> his service/company to anyone who is looking for mold treatment services. <br /> <br />"

"We thought the problem was finished in January after we had used Accurate Pest Control, but then after hearing more pests, we called them and they said they would be right there. They came back at no charge which is pretty rare. They guarantee their work and I was impressed that they followed through. They are very friendly, very on top of things, very professional and very knowledgable. I can sleep now, it was definitely worth using them."

"Spec Pro was extremely thorough and engaging during the inspection. Ian explained to us exactly what he was doing throughout the inspection and was very candid about issues that were concerning and about those that were of little or no concern. For example, we were worried about some stains in the shower and Ian reassured us that the issue was likely a cleanliness fix, not an underlying issue. He climbed into the attic and inspected so thoroughly that he identified potential mold-like substances under the insulation. The report was promptly provided the same day and included detailed descriptions and pictures of the home. When we had follow up questions to clarify elements of the report, Ian was responsive and helpful."

FAQs for mold & toxic material test projects in 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.
