When you have mold, making the correct decisions right away is critical. Whether it’s mold in your home, school, place of work or apartment there are many factors to consider. Are you going to be involved in a Mold Lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need Post Mold Remediation Testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It’s important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages & property damages require different environmental tests to prove your case in court.

Mold Testing and Remediation questions, answered by experts

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

Most grass mold isn’t harmful to humans. Slime molds in particular aren’t toxic and may even possess some benefits. Other molds, like powdery mildew and snow mold, generally aren’t a concern, but can still cause allergic reactions and respiratory distress in those with high allergy risk and compromised immune systems.  

A mold inspection costs $660 for the average homeowner. This cost can range anywhere from $150 to $2.800, depending on the size of your home, the number and type of samples, and the number of hard-to-reach areas of your home that need testing. 

Places like air ducts, crawl spaces, and wall cavities are particularly inviting for mold spores but require more time from your mold inspection pro. Additionally, swab testing, where a surface sample from an area of your home is collected, generally costs $200 to $300 per area. Air testing, however, is more costly, ranging from $250 to $350, but can cost as much as $700.

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.

You might be wondering, “Is laminate flooring toxic?” The product does contain formaldehyde, which is found in the resins used to bind the wood fibers together. But the chance of overexposure and adverse reactions, such as allergy- or asthma-like symptoms, is low unless you are exposed to formaldehyde in other places, i.e., if you work with formaldehyde regularly outside the home. Keep in mind, too, that many household products have the potential to pose a health hazard, such as cleaning products.
