"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."

"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

Mold in HVAC ducts is a relatively common issue that homeowners struggle with—especially in humid climates or homes with poor ventilation. Moisture from condensation, combined with dust and organic debris, creates the perfect environment for mold growth. Homes with high humidity, leaky ducts, or clogged drains are more prone to this issue. Regular inspections and proper HVAC maintenance significantly reduce the risk of mold developing in your ducts.

Water and electricity are a dangerous duo, so you should always proceed with caution as you inspect your washing machine and attempt to fix or replace any parts. We recommend working with a trained professional when you have a big leak on your machine to avoid fire risks from short-circuiting and electrocution from live wires in your appliance.

Signs of mold under silicone caulk include discoloration or dark spots appearing through or around the caulk, a musty odor in the area, and visible growth on the surface of the caulk. Additionally, if the caulk feels soft or spongy, it could indicate moisture trapped underneath, which is a breeding ground for mold.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.
