"Jeff did our mold testing and was extremely thorough. He took the time to sit down and talk with us, interview and explain everything. He made follow up calls to make sure our apartment complex was doing what needed to be done (which they weren't). He is caring and concerned. I would recommend him to everyone. Thank you Jeff and God bless you Carol Giusti Catherine Oels"

"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!"

"Every cent spent for this project went to the right company, DJK. The communication and guidance from beginning to end was superb, especially thanks to Brian (on-site consultant) and Vanessa (project coordinator). Should I ever find myself back in an asbestos concern, DJK will be my first and only call."

Customers say: Quality work

"Keith performed the job in a much more efficient manner than I expected. We had mold in our walls and I thought we’d have to replace our bathroom vanity. He went above and beyond, was knowledgeable, insightful, friendly, and responsive. He provides recommendations about other aspects of the house in a tactful way that I find incredibly valuable as a first time homeowner. Highly recommend!"

Mold Testing and Remediation FAQs, answered by experts

Yes, mold can easily grow under your hardwood floors, especially if your house has recently flooded or if there is a leak from a pipe under the floor. Hardwood floors can trap moisture beneath them, creating the perfect environment for mold to grow. Similarly, mold can also grow under your wood floor’s surface paint.

Professional carpet cleaning can cause mold if the job is not done properly. There are two ways this can happen—if your carpet cleaner fails to dry the carpet properly, or if your carpet cleaner uses an excessive amount of water during the cleaning process. Mold can grow wherever moisture is present, so make sure you hire a pro who knows the process inside and out.

Black mold on wood is a very serious issue. Besides compromising the structural integrity of the wood, it poses significant health risks. Stachybotrys chartarum, commonly known as toxic black mold, produces mycotoxins that can lead to respiratory issues, allergies, skin irritations, and other health problems. If left untreated, it can spread rapidly and compromise the structural stability of the affected wooden structures. Immediate remediation and preventive measures are essential to mitigate the risks associated with black mold on wood.

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.

DIY kits are available for basic air quality testing, but professional services provide more comprehensive results and recommendations. While a DIY kit may seem cost-effective, a professional assessment is more thorough. Inspectors are better equipped to catch all pollutants and hazards, and you'll still need a professional to verify and act on DIY test results. Furthermore, some kits don't test for certain pollutants or only detect their presence without measuring specific levels (like mold spores). It's generally better to opt for a detailed professional assessment.
