"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

"Rick was very friendly and informative. We had him come in for a water system quote to remove iron and manganese from our water. He sampled our water, gave us the results immediately and also tested our air quality. He was so thorough and knowledgeable that we were able to close the deal on both a water treatment system and air purifiers that are already making a noticeable difference!"

"Rob Barish was very knowledgeable and informative. he was thorough and didn't try to rush through, he took his time to really do a good inspection and took the time to explain everything to me so I have better understanding at what I am looking at and looking for during the remodel. I would definitely recommend him to anyone in the NH area that needs a mold inspector."

"Everything went wonderfully with this company.  They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work.  Once they started, the team (three people came) worked together like a well-oiled machine.  One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring.  Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues.  They cleaned up after themselves very neatly.  They also replaced the light switch with a dimmer switch at no extra cost!  Well within my budget, and came in even lower than their original (FREE) estimate!  I would highly recommend this company to anyone in the Bergen County area.

"The technician did an excellent job. It did take a while to get the repair finished, but that was due to Bertazzoni delivering the parts. I have had multiple problems with this particular appliance. My range now works better than it did when new, but I have a feeling that even if I have continuing problems with it, American Home Shield will just repair rather than replace due to the cost of the range. By the way, I'm not exactly sure of the date of the repair."

Mold Testing and Remediation FAQs, answered by experts

The most common reason for a smelly dishwasher is a dirty dishwasher filter. The filter is responsible for catching food while your machine is running to prevent clogs. Over time, that filter gets more and more filled with food particles. Cleaning your dishwasher filter monthly can keep the smell at bay.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

Both an air purifier and a dehumidifier can help prevent future mold growth, but neither can remove existing mold. An air purifier will improve air quality and trap mold spores in the air, whereas a dehumidifier will reduce moisture in the environment. Keep in mind that you need to make sure your air purifier uses HEPA filters, which are rated for mold removal.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

The best way to measure moisture levels in drywall is with a moisture meter. Moisture meters feature small probes that you insert into drywall (similar to pushing a pin into the wall). Ideally, you'll take moisture readings at several locations on the wall to get a general idea of the moisture level.
