"William Kimble was very quick to respond to our search for a mold inspection. He called us within minutes of our search. my wife spoke to him and explained our concerns regarding an occasional odor in our home , We wanted to know if it was a health hazard. William explained about the air samples they could capture and then have them checked at the lab. He came the very next day and took samples and had the lab results the next day and called my wife to tell us no dangerous molds here and emailed us the lab reports at that time. We are glad we found him and would recommend him to our friends. He is very personable and our dog Charlie took to him immediately and followed him around like they were old friends."

"Zach from EZ environmental LLC was nothing but phenomenal. I got jammed up with the department of health with a stop work order. I needed someone to respond immediately and reaching out to Zach was the right move. I had an asbestos sample that came back positive, Zach was right on it. He connected immediately with the health department inspector and negotiated the scope of work required. He saved me huge money on the abatement, communicated efficiently and walked me through each steps of the process. His work was neat, and his price was very reasonable. He got me the clearance as he said he will. Zach made a process that could’ve been very stressful so easy. Ez environment was just great for the job and will be using them for my future project."

"I had to have the guy come back because the work was incomplete. He complained the whole time about the work that needed to be done at the price he quoted to me. I would have rather paid more money to go with someone else than deal with the lack of professionalism."

"Scott Bacon of Certified Radon Systems, LLC is the best! If you need radon mitigation, I highly recommend Scott Bacon and Certified Radon Systems, LLC. We saw a mansion for sale in another state online and bought it. Of course, there are lots of things to fix up with the new house, including radon mitigation. Before we even set foot in the house, Scott evaluated the property and set up a mitigation plan. He worked with us remotely, so we didnâ  t have any extra costs of flying out to the new home before we were ready to move. And he installed the equipment on time and without a single problem. Scott also followed up after the install and did some testing to make sure the systems worked properly. The house is enormous, but the cost for the mitigation systems was extremely affordable. Scott Bacon and Certified Radon Systems, LLC were ultra-reliable and did a fantastic job! If you need radon mitigation, use Certified Radon Systems, LLC. Youâ  ll get excellent customer service and peace of mind knowing you are working with professionals to safeguard your home."

"Job was completed in short order. Basement is completely, FRP paneling was installed and looks great throughout. My only complaint is that there was a ton of concrete dust left behind, both in the basement and tracked through the family room. I would still recommend them."

Biohazard 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.

Painting over mold is not an effective solution and can actually make the problem worse. Instead, it traps moisture, which allows mold to grow and spread beneath the surface. Mold must be completely removed before painting to ensure the problem doesn’t recur. If mold is painted over, it may eventually seep through the new layer of paint, causing discoloration and peeling.

Many providers offer mold remediation as part of water recovery. Confirm with your contractor.

If your roof was constructed between 1930 and 1970, there’s a possibility that the shingles contain asbestos. If that’s the case, you should hire a professional for repairs and replacement, as they’ll have the necessary equipment to stay safe from such a hazardous and cancer-causing substance. If your home was constructed after this period, it’s unlikely that the shingles in place are toxic. In most cases, asbestos shingles are not recyclable, while standard asphalt shingles are recyclable.

Some plants that are toxic to animals or insects are also toxic to people. Daffodils, for example, are considered poisonous to humans (although they are rarely fatal). Most of the other plants listed above, however, are safe (and delicious!) for humans to eat, including basil, rosemary, and lemongrass.
