"We could not be happier with Charles Schwartz and Environmental Assessment & Solutions. We had a sudden severe mold outbreak from a leak in the boiler that caused serious damage to our basement. Charles was on scene within several hours, and was able to locate and stop the leak himself. He was highly organized, professional, and efficient and got the air testing and repair process underway in lightning time. As someone on chemotherapy to whom mold is potentially dangerous, I especially appreciated his professional background in health services. He always did what he said he was going to do, when he said it was going to be done. He saw us through every step of the process. Not only did he perform all services to our great satisfaction, he also seemed to genuinely care about our well being. This was a major crisis for our household, and we feel very grateful that we found such a consummate and experienced professional to help us navigate the process from beginning to end. Would highly recommend Charles and Environmental Assessment & Solutions to everyone."

"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 needed to have a mold issue addressed in my condo which had developed due to a leak in the roof. I contacted Aerotek Environmental having received their contact details from Angi Ads. From my first contact with Brandon of Aerotek Environmental he was the most helpful of all that I had spoken to about my issue. In addition to giving a reasonable cost estimate, Brandon took the time to carefully explain the step by step remediation process that his company would provide which included digital photos before, during and on completion of work. Having decided to use Aerotech the process ran very smoothly from setting the schedule date through the actual work and payment for services. Communication with Brandon was excellent - If I called or sent a text Brandon would either promptly answer or respond in a very short time. On the scheduled day, Felix Castro (job foreman) and his team arrived on time. Felix explained in detail exactly what he and his team would be doing. On completion of the work, Felix ensured that all debris was removed and provided full details as to what had been done and what he and his team found to be the most likely area of the leak. I am very satisfied with the entire process of working with Brandon who along with Felix and his team provided excellent customer service and would not hesitate to call in again should the need arise. I would highly recommend Brian and Aerotek Environmental to anyone in need of mold remediation services"

"Thank you Home Advisor for having Ace Cleaning Restoration as a recommendation. Project: Test for Toxic Materials & Mold Mr. Arman was very informative even before he came to our home to inspect our dilemma. His initial service was "free". After checking all the possible options, he offered three (3). We followed his recommendation. Excellent service and professional advice. Ray C. in Clifton, NJ"

"They weren't forthcoming about additional testing. Base inspection $299 then additional $400+ for lab testing. Wish I had known for vendor comparison purposes. However, I think it was worth it. Owner said the techs need to be instructed to say it was optional, but it helps you better understand the mold your dealing with. Glad I did it but not sure if it could have been done for less."

"Jeremiah was amazing with customer service. Attentive, always responded. Lamar was the technician. I just didn’t feel like he had a lot of experience but he was here quite awhile, inside and outside the home. Jeremiah said they charged $299 and no mileage fee, but did not mention that the two tests to see if it was black mold would be $700! That was upsetting but you were stuck because you had paid $300 for him to come out. It took a while to get tests back but that wasn't their fault. Just wish we hadn't been blindsided, but otherwise very reliable."

"Mark from NAL is the definition of a PRO! He was timely, efficient and very well read on his trade. I immediately felt like I finally had someone on my side after months of being told I was crazy. Thanks to Mark I got out of the toxic environment and have a health place to work from. Can't recommend this company and Mark enough. This is an employee who takes true pride in helping those with damaged apartments, mold, and asbestos. 5 stars!"

"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."

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