"We had a great experience with Pure Maintenance. We had the most direct contact with Ryan, Jeremy, and Rolando and they were all fantastic. There was great communication throughout the process of our water and mold remediation.

"Did you know mildew is the gas given off from mold?? Joe offered great advice about the growth of mildew into mold, and my landlord's responsibility to remove it. I feel that he is knowledgable and would perform a thorough inspection. Based on my present economics and quotes from 2 other firms, and not to discount Mold Testing CO at all, I decided on another company. Joe at Mold Testing CO is definitely my second choice."

"For clarification, the project was mold mitigation and restoration, not testing. Scott (owner) was great, able to jump right on the project and complete in timely fashion. The final cost was several hundred dollars under the initial "worst case scenario" quote."

"All and all they were professional on time and I really needed to know the answers I got. But it would have been nice if they had encluded the radon test, for the price paid! Also I was told they would help me all the way through even with resources and med. if needed. To good to be true. Maybe a little."

Mold Testing and Remediation FAQs, answered by experts

Inhaling black mold spores, even from behind walls, can cause people to have a wide variety of potential health issues. Some people may only notice a few breathing problems, while others can become quite sick with symptoms related to severe allergies. Constant exposure to mold spores can lead to lung infections and other long-term health problems. If you believe you have black mold inside your walls, you will want to reach out to a pro for an inspection and for advice on how to take care of the problem before it causes severe illness.

Iron sediments from rusty pipes are not likely to cause health problems. While a glass of yellow-hued water is off-putting, it is generally safe to drink yellow water in the short term. But you certainly want to address this problem. In the meantime, switching to bottled water until the yellow water issue is resolved is a good idea. 

Both mildew and mold come from fungi. One of the main differences is that mildew’s texture is dry and powdery, whereas mold is fuzzy and slimy. In addition, mildew isn’t very thick, while mold looks three-dimensional. Also, mildew is typically light in color, whereas mold comes in various shades, including green and black.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

While metal ducts are known for being the most durable choice, flex ductwork is a safe alternative with a host of additional benefits. The key to installing flexible ducts is to make sure they’re properly sized and installed. For optimal results, it’s always best to hire a duct installation pro who has extensive experience with flex duct installation.
