"I contacted Home Advisor looking for a mold inspection company on a Saturday. Within 10 minutes I received a call. I m in California and my daughter attends school in Mississippi. She has been very ill since moving into the house she is renting. I hopped on an airplane and meet with the inspector Monday. The inspector was completely professional and knowledgeable. The results were back in less than 24 hours, from an independent lab. I highly recommend this company!"

"Redeemers Group was prompt, courteous, and professional all around. I called regarding cracked bricks on the outside of our home, concerning for a foundation issue. Scheduling was easy. They called the day before to confirm the appointment and who would show up to our house. The day of inspection Jay called 15 minutes before arrival, and arrived exactly on schedule. He and a colleague (Kirk) were courteous and professional. They even took their shoes off in the house, which my wife loved. They visually inspected the area of concern, and performed professional measurements using a leveled tripod laser. Jay and Kirk determined the crack was due to construction and we had no current foundation problem. They provided advice for keeping water away from our home, and for monitoring the foundation over time. The company also sent a detailed foundation package in the mail so I could read on the topic before the inspection. Overall fantastic experience and I would recommend to those in need of a foundation inspection or repair estimate."

"It turned out well. I used it shortly after I purchased the deal. There were additional charges beyond the big deal amount as I had them repair something that they found while doing it. They did everything as advertised and then in addition to that, they also fixed some molding around the chimney that had become cracked and weathered. I had not used them before. There have been no issues since the service was provided."

"Other than that, I was happy with them. American Home Shield recommended Destiny Air of Alvin, TX. I was happy with them until now. In July, the 10 month old air conditioner, dehumidifier did not work. Someone came out on July 6th and supposedly fixed it. I was gone until coming home the end of July and the humidity upstairs was the same. Someone came out on August 8th and repaired it as of today, it is drier upstairs. In the meanwhile, black mold came through the air ducts. Someone is supposed to come out on August 29th in the morning to take care of this. Today is the 25th, I have been calling them up to seven times a day with no response. The downstairs AC is 3 years old. Coming home on the 19th after a lovely trip- that AC did not work. It took 6 days for a service man to come out. He was 2 hours late, discovered something had to be replaced and it had to be ordered. It should take 2-3 days. Today, is 6 days later and nobody has called me back. I'm sitting here in the heat, can't really live upstairs because of the black mold. I'm at a loss for what to do."

Mold Testing and Remediation FAQs, answered by experts

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

Certainly, DIY mold tests are not perfect when trying to determine whether you have a mold problem. They could give you a false positive reading, or they may fail to detect mold that’s behind a wall, especially if the infestation is still small. Ultimately, you should seek a mold inspection if the DIY test gives you a positive result, just to be certain. And if the test is inconclusive, it’s probably worth seeking an inspection from a pro.

Mold thrives in high-moisture environments, whether that’s steady leaks or just high condensation. Around the house, common causes of mold include leaky pipes, a leaking roof, high humidity, poor ventilation, a damp basement, rotting food in the fridge, wet clothing and towels not hung properly for drying, a leaking foundation, and a leaky air conditioner.

And, of course, if your home suffers from flood damage, you stand the risk of developing mold in the aftermath. That’s why it’s important to act quickly at the first sign of mold.

While bathroom mold, commonly known as black mold, does not produce harmful mycotoxins, it can still pose health risks. If disturbed, mold spores can become airborne and potentially cause allergic reactions, respiratory problems, skin irritations, and other health issues. This is especially true for individuals with allergies or sensitivities. While bathroom molds are not as dangerous as other mold species, prompt action is crucial to mitigate health risks and prevent further spread. 

Visible growth, musty odors, and water damage are common indicators.
