NAL East, from the very first time I called to get information, to the scheduling, and then their inspection were all amazing. They took such pride in their work, explaining everything in detail.. I got my results report with lab results and copies of the pictures and recommendations later that same evening. I called at 11:30 PM to leave a message but someone actually answered and connected me to the report interpretation department who helped me understand my entire report. Since, Iâ ve recommended them to two other friends of mine and I had them come and do my commercial building. They are 10 star.

Response from Company:

Thank you for the kind words. It is much appreciated. Thank you

Mark and Joe were terrific. Explained all the steps as they were working. Any questions I asked they were willing to answer. The process was explained to me in layman terms. They left yesterday and now waiting for the results.

5.0 Joseph B. Seaside Heights, NJ

Highly professional service and the assigned contractor (Mark) explained very technical information in a way in which I was able to easily understand it. Definitely a subject matter expert. He was very patient with my numerous questions and answered with the details I needed to make an informed decision on next steps. I would highly recommend!

Response from Company:

Thank you very much Mr. Bova. That review will go in to Mr. Stern file as well as it will be forwarded to his supervisor. Thank you again. Lisa Fox.

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.

5.0 Jeff D. Ardmore, PA

I got a call within minutes on a weekend after requesting help. The guy on the phone (name forgotten) explained the process in great detail, which I appreciated. Appointment was scheduled for the next day. Mark Stern, our inspector, showed up promptly. Having young kids, I was careful to follow and learn as much as I could. Mark was extremely thorough, poking around deep into the rafters, and explaining what he saw as he went. Mark was both knowledgeable and affable. He took a ton of pictures, recorded air samples, and within 24 hours I had a very thorough, detailed report. Not sure what more I could have asked for. Great work.

Inspector did a great job

4.0 Michelle H. Cresskill, NJ

Everyone I dealt with was courteous and professional. There is someone to assist 24 hours a day which is amazing. Mark and Peter came to my home for my testing and were excellent. My only negative comment is related to pricing. When I initially spoke with customer service my fee was to be $700. I then learned from Mark on the date of testing that was for 4 areas. Since I had more areas then that of concern I ended up paying almost $1,800 for 7 areas. I was not pressured in any way to do this but feel the customer service team should explain the tiers of their pricing in full so a client is fully informed.

Response from Company:

This property had more issues than in a normal situation. Additional sampling was recommended but not mandatory. We gave the client guidance and she decided to have additional testing conducted.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
