"Given the awful circumstances (house fire), we had a great experience with AC Environmental. They were quick, courteous and professional. As with every service, problems can occur. How a company reacts to a problem says a lot to their commitment to the customer. There was a minor problem in removing our asbestos, I called AC Environmental and Dustin was out at our house resolving it within hours! I was surprised and very pleased."

"Overall was good for what the service is. The technician was a postal worker and home inspector. So mold test company appears to be brokers. Their pricing was competitive from other quotes I received but I honestly think it was pricey for time spent and what they do. But like I said the price was pretty standard from the companies I called, in my opinion. But the technician was attentive and knowledgeable, and friendly."

"After recently buying an older city house, we found a small amount of what was very likely to be deteriorating asbestos in our basement. I called Environmental Services and they sent someone out to have a look within a few days, and quickly assessed the problem. It was a small project, so they were able to schedule it for two days later. They gave us a reasonable bid, were professional, and knocked out the job in 4-5 hours, with a total turnaround time from our first call to completion of the project of 6 days. This was a huge relief for us, and turned what we thought might be a big problem into something relatively minor. I highly recommend this crew!"
