"Dave was super helpful and steered me toward the real solution I needed -- not testing but direct remediation of a leaking window and wall. His experience really helped get the job done and to calm my nerves after I discovered the leak!"

"We hired McCormick to remodel our master bathroom, and the process couldn’t have been smoother. Khaled guided us through everything, and his team was skilled and respectful. They handled the job efficiently, stayed within budget, and kept our home tidy. Now, our bathroom feels like a relaxing oasis, with high-quality finishes and a modern touch we love. McCormick’s attention to detail really made the difference, and I’d gladly hire them for future remodels. This experience was everything we hoped for."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

Biohazard Remediation questions, answered by experts

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

If you’re worried mold might still be lingering after you’ve cleaned your items, here are signs to watch for:

  • Musty smell

  • Visible spots or stains

  • Allergy symptoms when you’re around the item

  • Damp or sticky feel.

If you notice these signs, it might be time to let go of the item or get professional treatment.

Slime mold isn’t toxic to your dog, even if they eat it. Toxicity and comfort are two different things, and if you notice your dog eating slime mold, you should stop them, but not worry too much. Expect a period of gastrointestinal distress, and possibly some other complications, but your dog should be ok within a few days.

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.

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.
