"They did a very good job. Brian explained the procedures to me clearly and he explained what would be needed depending on the analysis results. He took tiles samples and commissioned lab analysis to determine which procedure was needed. His pricining were transparent, competitive and clear he took great care to educate me. Everyone was polite and they left everything cleaned and in good shape! I would absolutely recommend them! And would use them again!"

"Charles was invaluable to our project. We called him before starting a renovation because we live in an old house and wanted to make sure there was not asbestos in the walls before tearing them down. He took asbestos samples and luckily there was no asbestos. However, when he was here, he noticed mold all along the floor edges in the sunroom. He took samples of the mold and the air. He also suspected mold in the air handler to our HVAC. He was extremely thorough in his inspection of our home. Sure enough, there was mold present. He helped us find a mold remediation expert and supervised the job. When the mold remediator was finished, Charles found a spot that they missed so was able to facilitate bringing the remediator back to complete the job. Charles goes above and beyond in terms of his availability, his involvement throughout the job, his willingness to provide advice and his help in working with contractors. He is extremely knowledgeable. In addition to the above work, he is now helping us with post renovation cleanup. Our general contractor removed fiberglass insulation without proper precautions, so our entire upstairs is covered in fiberglass dust. Charles helped refer us to an appropriate cleanup service and he devised a work plan that will keep us all safe during cleanup. I can't say enough about Charles's professionalism, devotion to his job, generosity with his time and his expertise."

"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"

"No one wants to find mold in their home (or in our case, the home we were buying), but everyone wants to find good, reliable, knowledgeable people to help them, and Johnnie definitely fits the bill. We were referred to Johnnie and got him on-site the very next day he was very accommodating. He spent a ton of time not only carefully working in the house, but gave generously of his time to explain things to us thoroughly. He was very honest, gave us his unfiltered assessment based on his expertise (which we appreciated), and we can not recommend him enough. If you are looking for someone who is personable, reliable, reasonably priced, and really good at their job, hire him, you will not be disappointed."

"The remediation went great. I was on vacation, so he coordinated with my contractor who was doing work. The job was finished when we got back. It was done exactly as described. Radon level went from 5.1 to 1.7. The only downside is you need to close the permit yourself after the project. But they do a great job, exactly as described.

"Called as I suspected potential mold. They were out the next morning to get it tested. Confirmed a few days later it was bad mold, explained the job and what was next. Worked around my schedule and came on time and completed the work promptly. The section of wall where the mold was looks good as new and the workers were great to deal with. Hopefully I never have to worry about mold again, but will certainly reach out to certified mold removal if I need to."
