"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

"The whole experience was amazing! When Eric came to look at the house he explained everything to us so we would understand the process and what to expect. He let me know how common this happens and it even happened to him recently which made me feel better. They were super efficient, quick, and caring. They even use green products which is a plus having a pet. I would recommend them to friends family and anyone else who needs their help with the services they provide. Very affordable for us and money well spent! Thank you so much for making the house feel more comfortable and the air so much cleaner!"

Mold Testing and Remediation FAQs, answered by experts

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

Pressure-treated wood offers some protection from the elements but doesn’t protect against mold. However, if you spot mold growing on pressure-treated wood, it doesn’t indicate rot or an interior fungal infection—the treatment process ensures that the mold stays on the exterior. Keep the wood dry, but if you spot some mold, remove it immediately and clean the area.

In mild cases of mold growth, you can DIY mold remediation with a simple cleaning using safe and natural cleaning solutions like baking soda, hydrogen peroxide, vinegar, or lemon juice. However, if the mold is larger than 10 square feet or you suspect toxic black mold, you should not do mold remediation on your own. Instead, you should hire a professional mold removal company to handle the job.

Mold can come back after cleaning, especially if the conditions are right. Mold loves moist environments, so if you clean a piece of furniture, then put it back in a humid area, the mold can return. Mold may also return if you missed an area during cleaning. A professional mold remediation company can help ensure that the mold is gone for good.

No, it isn’t. This is one of those things that needs to be dealt with immediately because mold will spread at a rapid rate and can go from just one spot on the wall to a serious health risk in a matter of days. Prolonged exposure can be extremely dangerous, so any mold issues (or even suspected mold) need to be dealt with right away.
