"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

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

The pink mold appears because of the presence of a naturally occurring airborne bacteria called serratia marcescens. When this bacteria lands on a moist surface, it multiplies, creating the pink film. To reduce the ability of this bacteria to multiply, use a bathroom exhaust fan to reduce humidity in the bathroom. Regularly clean the interior of the shower with a disinfectant as well.

It is not advisable to shower in a bathroom contaminated with black mold due to the potential health hazards it poses. Inhaling mold spores during showering can trigger allergic reactions, respiratory issues, and skin irritations, especially for individuals with pre-existing allergies or respiratory conditions. Prolonged exposure to black mold can result in severe health complications. It is crucial to eliminate any black mold problems in your bathroom before continuing with showering to ensure a safe and healthy environment.

Bathroom mold tends to reappear due to the persistent presence of moisture and humidity, creating the ideal conditions for its growth. Since bathrooms are inherently humid environments, without proper ventilation, moisture accumulates on surfaces, providing a continuous food source for mold spores. Mold spores are present in the air and settle on damp surfaces to start growing rapidly. Additionally, if the underlying causes of mold, such as plumbing leaks or inadequate sealing, are not addressed, mold will return even after removal. To avoid recurring issues, addressing the root cause by improving ventilation, fixing leaks, and maintaining a dry bathroom environment through regular cleaning and maintenance is essential.
