"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Our approach allows us to provide our clients cleaner and healthier living by utilizing practical experience, technical excellence, and client responsiveness.

"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"

Our services include Mold Testing, Remediation and Water Extraction as well as Air Duct Cleaning and Sanitizing. We have more than thirty years experience in the building industry. We are capable of repairing any damage caused by mold, water, fire or the remediation itself. We have full compliment of licensed sub- contractors, Electric, Plumbing, Masons etc. Servicing all of New Jersey.

"AMS is our HERO. The city sewer backed up and filled one third of our basement just before kickoff on Super Bowl Sunday. By halftime George had arrived. He calmly assessed the situation, and set up a time to return the following morning. His workers were polite, professional, and meticulous, and did an unbelievable job of cleaning up a horrible mess. By the end of the day the damaged items, sewage , and much of the smell was gone. Huge fans and a germ-killing ionizer ran for three days. When they were finished the floor was bone dry and absolutely clean. It occurred to us that the floor could not have been better cleaned if it were being prepped for painting. So we will be doing so. AMS has innate integrity and a wealth of knowledge across a wide spectrum. Any project can be entrusted to their competent hands. Chester and Jean Lehmann"

My clients and their attorneys rave about my work. During your inspection, I happily walk you through all the important features of your new home.

Please read my reviews on Angie's list and know that my past customers would say the same.

"I had got my House Inspected from Mark on Aug 2022. everything went fine until I moved into the house. Couple of months after move-in I found old dried water marks in storage and HVAC room in my basement. I was hoping that these water marks were owing to old water heater leaks but then in early 2023 there was heavy rainfall and the HVAC room basement started leaking water into the room. It was then I found that there was a crack in the basement wall. This crack is next the furnace duck and quite easily visible. Mark suggested that he is a season home inspector but I doubt because he missed visible evidence of prior basement flooding and a basement crack that was easily visible. I contacted Mark and send him proofs of his grave mishaps. He asked for proofs whether i have applied the suggested fix per inspection report, to which I promptly responded and then he stopped responding on my emails. He is not the person to get you house inspected"

Radon Detection and Reduction questions, answered by experts

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed.
