"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

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.

When you smell something, it’s because the particles of what you are smelling are floating through the air. If you smell mold, it means that it’s airborne, and whether or not it’s harmful depends on the type of mold. It’s very hard to tell the difference between molds, even with the internet to guide you. Call a professional as soon as you see mold, they will test it, remove it, and make sure you aren’t breathing anything harmful.

Yes, air duct cleaning can remove mold from the interior lines of HVAC systems. Professional air duct cleaning companies use tools and methods like brushes, cleaners, and vacuums to remove mold from air ducts. For successful mold remediation, it is essential to hire a reputable and experienced air duct cleaning service. Keeping your air ducts clean can also help prevent the conditions that allow mold to grow and thrive in your ductwork.

After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To get rid of a mold smell, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area. Call a mold testing professional for another inspection.
