"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

No, a dehumidifier does not actually remove mold. It only reduces the moisture in the room, which mold needs in order to grow. If you already have mold, you’ll need to do a deeper cleaning or call a pro to remove the existing mold first.

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.

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.

Mushrooms do not harm your yard. In fact, they can actually help improve your lawn health by decomposing woody organic matter in your soil, and breaking it down into nutrients that feed your grass and plants.

If you have the appropriate dehumidifier for the volume in your home then no, they shouldn’t be left on all day. Dehumidifiers have a motor that operates a compressor. In some ways, this is similar to a car and like a car, a dehumidifier needs periods of rest. Ideally, you would run a dehumidifier less than 45 minutes per hour with a break for 15 minutes. Still, this is the upper limit of what you should do.
