"Presley did a survey and informed me of the work required and timing involved. He was courteous and patient. His crew, Greg and Dana, were on time, kept me informed of the work progress, did all necessary scrubbing of my entire place, and left it completely clean - all 3 types of toxic mold spores erradicated. I recommend P&M Mold Pro highly."

"I hired AAA Lead Pros to do the mold remediation in my basement. Within an hour of my initial call someone came out to give me an estimate and mold assessment report. Initially, I was not happy to find they charged for the estimate. Once I received the quote back that quickly changed. Lead Pros are extremely well priced. I’m talking a third of what their competitors attempted to charge me. They were also willing deduct the cost of the estimate off the final price of the job. I hired them on the spot after receiving the quote and they were on the job site within a week. As for the work itself, I could not be more satisfied. The supervisor was friendly and willing to ease the concerns of both myself and the tenants by answering an onslaught of our questions. Once the walls and floors started being torn down it became clear to them that to do the job correctly far more material would need to be removed than what was initially agreed upon. This was done at no additional cost to me which made it clear in my mind that they are dedicated to getting the job done correctly without trying to take advantage of their customers. The mold killing agent that was used was a green product so it was not necessary to vacate the premise during the time the work was going on. All contaminated materials were removed and hauled off site. Anything which could not be removed (structural support beams) were treated and encapsulated. They also used an air scrubber which was left running for 24 hours straight to ensure any disturbed mold spores would not further contaminate the air and job site. After the job was concluded I felt compelled to tip them for their great service. They wouldn’t even accept the tip! This is why I felt personally obligated to leave them this positive review. I am normally very skeptical of contractors so it is refreshing to find an outfit like this with integrity. They will absolutely be getting my business again should the need ever arise."

"Mark Stern of NAL was terrific. He explained the inspection process in terms that we could understand. He returned our calls immediately and showed up when he said he would. Very professional. Report was perhaps a bit more detailed and technical than we needed but was very thorough and informative. I would strongly recommend Mark and NAL to anyone needing mold testing."

"Christian is very knowledgeable, helpful, fair, and thorough. He tested our air quality for mold, asbestos, and lead. He is not trying to upsell you but gives you an honest assessment of what’s going on and options you have to address them. Also, from my research, his services are very fairly priced."

"I had a tenant who believed had mold in their apartment. I called Apex and David was helpful right from the start. He did everything he could to win the trust of the tenant. He was as thorough as possible in his testing and provided first-class service. It turns out in we did not have mold and he provided all appropriate documentation. David is a true professional every step of the way. He was responsive to my needs and answered my phone calls and texts in a timely manner. I would use him again in a heartbeat."

FAQs for mold & toxic material test projects in Union, 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.
