"Noah scheduled an estimator to come to my house 30 minutes after my phone call. Moises came and gave me a reasonable price. He was prompt and courteous. The next day Hiram and Orge came to do the work. They were prompt and friendly. They did an excellent job removing the mold. Brian called me to keep me appraised of what they did and how long they will be leaving the dehumidifier and other drying equipment in the garage. This company is prompt, professional, and courteous and did an excellent job. I would definitely use them again."

"My insurance paid Ivan directly for mold detection and remediation, which was completed quickly. We subsequently hired them to repair/remodel the entire bathroom, which they are in the process of doing (also as quickly as can be expected), in spite of having to deal with an extremely difficult and unpleasant tenant!"

Customers say: True professional

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

Mold Testing and Remediation FAQs, answered by experts

There are different types of mold, and not all humans are the same. For example, a more toxic type of mold may have less of an effect on a healthy person than a less toxic mold in the home of someone who is immunocompromised. If you recognize any symptoms of mold poisoning—sinus issues, brain fog, respiratory distress, constraint cough, migraines, or any others—call your doctor or go to the hospital before you attempt any removal.

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.

Using bowls of water for humidity can be an effective way to increase the humidity level in a room, but it's essential to consider potential risks. Placing bowls of water near heat sources might pose a hazard as they could spill, causing damage or creating slip hazards. Moreover, stagnant water can become a breeding ground for bacteria or mold (you really want to get rid of black mold stat) if not changed regularly, potentially negatively affecting indoor air quality. Water bowls can also accidentally spill onto surfaces, causing water damage to furniture or flooring. Regular maintenance and cautious placement can mitigate these risks.

Yes, mold in the basement of your home will affect the conditions upstairs. Mold spores can travel through the air and into the supply vents of your home’s ventilation system. It is extremely important to remove any mold in your basement as soon as possible so it doesn’t affect the health of those living in the house.

There are two types of mold symptoms in the home: visible mold and unexplained health issues. If you have allergies out-of-season, brain fog with no other obvious cause, constant congestion, and other such symptoms, you may have a mold problem. Oftentimes you can smell mold in your home, even if you can’t see it.
