"I dislike providing reviews unless my experience was stellar, but that undermines a major benefit of Angie's List. After I purchased the visit to diagnose the problem, the company did not contact me to to schedule an appointment nor did they respond to my first contact with them. After a week passed, I contacted them again and successfully scheduled a time. The company representative had ideas about the cause of the mold, but he was most interested in selling us a commercial dehumidifier for our craw space at a cost of $1,700. I repeatedly questioned him about the link between our mold in the garage and the crawlspace, but he was never able to explain how the dehumidifier was necessary. Indeed, he had missed seeing the grates in the crawlspace that vent outside the house. We would have been trying to dehumidify west Knoxville. When I showed him the vents, he still wanted to sell that dehumidifier. I wanted him to cut into the dry wall in order to verify that there was no mold problem inside the wall. He would not do that. Master Dry does not repair dry wall. I had a handyman replace the dry wall and verified that the mold problem was not more extensive."

"You certainly get what you pay for! While CSI wasn't the cheapest on our list of home inspection and radon testing quotes, the cost was more than reasonable for the level of service that we received. Ron, our home inspector, was fantastic! He arrived early, and I don't think he could have been more thorough than he was! He was very friendly and personable, and was more than willing to answer our questions during the inspection. He went through the entire home with a fine toothed comb! He pointed out defects that he found, and explained things in detail. He also highlighted the positive things he found. Used a drone to inspect the roof and chimney, and thermal imaging to check for hidden moisture. I feel like we have an excellent idea of the condition of the property we are buying, which has done a lot in making us feel more comfortable! The report we receiced within 24 hours was professional and clearly written with appropriate photos attached. Will certainly recommend to others, and will use them for any future home inspection needs we have!"

"Very well. Workers arrived promptly and worked steadily. They inspected for mold in my basement, removed duct cover where mold was found, built a new cover, applied mold preventive to the whole basement, and did an awesome clean-up, including vacuuming the whole basement. I was pleased that the job was done well and finished in a day. One worker returned two days later to sand the drywall, which had needed time to dry completely. I appreciate how they explained everything they were doing."

Mold Testing and Remediation FAQs, answered by experts

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

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 doesn’t require much airflow to make it out from behind walls and into your living space, making you sick. HVAC systems can actually pull the mold from behind walls and spread it through your home. While the mold may be out of sight, moisture transfer from the wall can also spread the mold from behind the wall into your living space and air. Any cracks in the walls or bad insulation only compound this effect. 

In most cases, it's not worth the risk of buying a home with mold. You should carefully weigh the pros and cons before making a decision—and there are far more drawbacks than benefits. For one, buying a house with mold opens you up to health risks since mold can cause respiratory and allergic reactions. If the mold is widespread throughout the home, the cost to completely remove it, make necessary repairs, and prevent it from returning is often not worth the cost savings of buying a mold-infested home for a bargain.
