"I would highly recommend DJK. They remediated the asbestos in my attic and encapsulated the asbestos tape on my ductwork in the basement. They were professional, knowledgeable and easy to work with. Their quote came in much less than expected."

"I did not know I had a high radon level. I contacted Gardner and they installed a remediation system. It took 4 men 9 hours to do the work. When it was done it looked professional and they cleaned up as well."

"Lifetime radon service did a great job of explaining the process of installing the remediation system as well as options we had to help control the costs of the project to within our budget. They were also flexible and allowed to replace the sump pump on our own prior to installation so that we were able to install the model of sump pump that we wanted."

"US Waterproofing was great. Finished job looks terrific and they did a tremendous job cleaning up after themselves. In particular, it appears their dust remediation system really did the trick because I was expecting a ton of dust from the jack-hammering and their really isn't ANY to speak of. I want to give a particular shout-out to the crew that worked on my job. The initial work was on a cold, rainy, miserable day and those guys went in-and-out of my house all day long lugging buckets of dirt by hand. Hard to think of a more thankless task in worse conditions--but those guys worked their butts off. I was thoroughly impressed. Wish I knew their names--but thanks so much. Great work."

"Todd Szada at Umbrella Environmental was awesome! He recommended that we get our vinyl tested for asbestos prior to any attempt at removal - the logic being that if the material did NOT contain asbestos, there would be no need to remove the material. He promptly visited our residence soon after we reached out and obtained a sample, had it tested and let us know that the vinyl did not contain asbestos and there was no need for removal. He saved us a great deal of money and simultaneously sacrificed additional business to help us. Todd is a consummate professional and we are very grateful we found him!"

"Working with Damian was the easiest part of restoring my fixer upper! He's incredibly easy to work with, transparent and honest, and does great work for great prices. He managed to get started right away for me since the mold in my house was indeed toxic, and I couldn't be more grateful for the positivity he brought to what has been a very stressful situation for me. I couldn't recommend him more!"

Biohazard Remediation FAQs, answered by experts

It’s unlikely your leaves are a hazard, especially if you get to them while they’re dry. However, a couple of rare risks exist. University studies suggest that decaying leaves can produce organochlorines, toxic pollutants similar to man-made PCBs (polychlorinated biphenyls), so avoid keeping them in an enclosed area.

Also, leaves and compost may cause the growth of fungi that can cause diseases like histoplasmosis and aspergillosis, as well as mold spores that are unhealthy for human lungs. Again, severe issues are rare, but those with compromised immune systems or allergies to mold should wear face masks when directly handling leaves.

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.

Follow recommendations for removal or remediation to ensure a safe living environment.

Mold thrives in wet and humid conditions, and the bathroom can often be an ideal place for it to grow. If you are worried about mold, it's a good idea to hire a local mold inspector to inspect your bathroom. 

How you handle the mold depends on the extent of the issue. If it's on the caulk or other surface, a deep cleaning with mold-killing products such as vinegar or bleach may be sufficient. For a large infestation, you'll most likely need professional mold remediation.

Mold remediation costs between $1,200 and $3,750 in most cases, but the exact price will depend on the extent of the mold issue and how accessible your attic space is. Keep in mind that this price range only includes the removal of damaged materials. Your total might be significantly higher if you need professionals to provide build-back services, too, like replacing damaged insulation or roof decking.
